Since the mempool unbroadcast mechanism handles the reattempts for initial
broadcast, the wallet rebroadcast attempts can be much less frequent
(previously ~1/30 min)
When a CWallet doesn't have a ScriptPubKeyMan for the requested type
in GetNewDestination, give a meaningful error. Also handle this in
Qt which did not do anything with errors.
FillPSBT will add our own scripts to the PSBT if those inputs are ours.
If an input also lists pubkeys that we happen to know the private keys
for, we will sign those inputs too.

Pull request description:
`-upgradewallet` is largely incompatible with many recent wallet features and versions. For example, it was disabled if multiple wallets were used and would not work with encrypted wallets that were being upgraded to HD.
This PR does away with the old method of upgrading upon startup and instead allows users to upgrade their wallets via an `upgradewallet` RPC. This does largely the same thing as the old `-upgradewallet` option but because the wallet is loaded, it can be unlocked to upgrade to HD. Furthermore it is compatible with multiwallet as it works on the individual wallet that is specified by the RPC.

Pull request description:
Extracted from #16944
First this PR simplifies the check when generating a change address, by dropping `CanGetAddresses` and just letting `reservedest.GetReservedDestination` do this check.
Second, when the keypool is empty, instead of immediately giving up, we create a dummy change address and pass that to coin selection. If we didn't need the change address (e.g. when spending the entire balance), then it's all good. If we did need a change address, we throw the original error.

When a wallet uses avoid_reuse and has a large number of outputs in
a single destination, it groups these outputs in OutputGroups that
are no larger than OUTPUT_GROUP_MAX_ENTRIES. The goal is to spend
as many outputs as possible from the destination while not breaking
consensus due to a huge number of inputs and also not surprise the
use with high fees. If there are n outputs in a destination and
n > OUTPUT_GROUP_MAX_ENTRIES then this results in one or many groups
of size OUTPUT_GROUP_MAX_ENTRIES and possibly one group of size
< OUTPUT_GROUP_MAX_ENTRIES.
Prior to this commit the coin selection in the case where
n > OUTPUT_GROUP_MAX_ENTRIES was skewed towards the one group of
size < OUTPUT_GROUP_MAX_ENTRIES if it exists and the amount to be
spent by the transaction is smaller than the aggregate of those
of the group size < OUTPUT_GROUP_MAX_ENTRIES. The reason is that
the coin selection decides between the different groups based on
fees and mostly the smaller group will cause smaller fees.
The behavior that users of the avoid_reuse flag seek is that the
full groups of size OUTPUT_GROUP_MAX_ENTRIES get used first. This
commit implements this by pretending that the small group has
a large number of ancestors (one smallet than the maximum allowed
for this wallet). This dumps the small group to the bottom of the
list of priorities in the coin selection algorithm.

Pull request description:
In many places, our code assumes that presence in the address book indicates a non-change key, and absence of an entry in mapAddressBook indicates change.
This no longer holds true after #13756 (first released in 0.19) since it added a "used" DestData populated even for change addresses. Only avoid-reuse wallets should be affected by this issue.
Thankfully, populating DestData does not write a label to the database, so we can retroactively fix this (so long as the user didn't see the change address and manually assign it a real label).
Fixing it is accomplished by:
* Adding a new bool to CAddressBookData to track if the label has ever been assigned, either by loading one from the database, or by assigning one at runtime.
* `CAddressBookData::IsChange` and `CWallet::FindAddressBookEntry` are new methods to assist in excluding change from code that doesn't expect to see them.
* For safety in merging, `CAddressBookData::name` has been made read-only (the actual data is stored in `m_label`, a new private member, and can be changed only with `setLabel` which updates the `m_change` flag), and `mapAddressBook` has been renamed to `m_address_book` (to force old code to be rebased to compile).
A final commit also does some minor optimisation, avoiding redundant lookups in `m_address_book` when we already have a pointer to the `CAddressBookData`.

This no longer holds true (due to bugs) and will shortly be made intentional.
Renaming the field helps ensure that old code using mapAddressBook directly gets checked for necessary rebasing.

This is a step toward removing the Chain::Lock class and reducing cs_main

This change affects behavior in a few small ways.
- If there's no max_height specified, percentage progress is measured ending at
wallet last processed block instead of node tip
- More consistent error reporting: Early check to see if start_block is on the
active chain is removed, so start_block is always read and the triggers an
error if it's unavailable
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
This change only affects behavior in the case where wallet last block processed
falls behind the chain tip. The rescanblockchain error height error checking
will just be stricter in this case and only accept values up to the last
processed height
FoundBlock class allows interfaces::Chain::findBlock to return more block
information without having lots of optional output parameters. FoundBlock class
is also used by other chain methods in upcoming commits.
There is mostly no change in behavior. Only exception is
CWallet::RescanFromTime now throwing NonFatalCheckError instead of
std::logic_error.
Currently it's possible for ReleaseWallet to delete the CWallet pointer while
it is processing BlockConnected, etc chain notifications.
To fix this, unregister from notifications earlier in UnloadWallet instead of
ReleaseWallet, and use a new RegisterSharedValidationInterface function to
prevent the CValidationInterface shared_ptr from being deleted until the last
notification is actually finished.

1168394d75 [wallet] Notify conflicted transactions in TransactionRemovedFromMempool (John Newbery)
Pull request description:
These boost signals were added in #9371, before we had a `TransactionRemovedFromMempool` method in the validation interface. The `NotifyEntryAdded` callback was used by validation to build a vector of conflicted transactions when connecting a block, which the wallet was notified of in the `BlockConnected` CValidationInterface callback.
Now that we have a `TransactionRemovedFromMempool` callback, we can fire that signal directly from the mempool for conflicted transactions.
Note that #9371 was implemented to ensure `-walletnotify` events were fired for these conflicted transaction. We inadvertently stopped sending these notifications in #16624 (Sep 2019 commit 7e89994). We should probably fix that, but in a different PR.

When the user doesn't specificy inputs, it makes sense to automatically select them. But when the user does specify inputs, we now fail if the amount is insufficient, unless addInputs is set to true.
The only CValidationInterface client that cares about transactions that
are removed from the mempool because of CONFLICT is the wallet.
Start using the TransactionRemovedFromMempool method to notify about
conflicted transactions instead of using the vtxConflicted vector in
BlockConnected.
Not all ScriptPubKeyMans will be able to provide private keys,
but pubkeys and scripts should be. So only provide public-only
SigningProviders, i.e. ones that can help with Solving.
Instead of fetching a SigningProvider from ScriptPubKeyMan in order
to fill and sign the keys and scripts for a PSBT, just pass that
PSBT to a new FillPSBT function that does all that for us.
CWallet::CanGetAddresses() is used to check whether the wallet has available or is able to produce keys for addresses. It uses the ScriptPubKeyMan::CanGetAddresses(), which in turn uses the const KeypoolCountExternalKeys() method, all which do counting and no modifications.
These functions are used to mark/check if a key of our own has been used to spend (and only for avoid-reuse wallets), which has nothing to do with the destination/address itself.
Give them more accurate names to avoid confusion.

6fc554f591 wallet: Reset reused transactions cache (Fabian Jahr)
Pull request description:
Fixes#17603 (together with #17824)
`getbalances` is using the cache within `GetAvailableCredit` under certain conditions [here](35fff5be60/src/wallet/wallet.cpp (L1826)). For a wallet with `avoid_reuse` activated this can lead to inconsistent reporting of `used` transactions/balances between `getbalances` and `listunspent` as pointed out in #17603. When an address is reused before the first transaction is spending from this address, the cache is not updated even after the transaction is sent. This means the remaining outputs at the reused address are not showing up as `used` in `getbalances`.
With this change, any newly incoming transaction belonging to the wallet marks all the other outputs at the same address as dirty.

* `ScriptPubKeyMan::GetReservedDestination` is changed to return the destination so that future `ScriptPubKeyMan`s can return destinations constructed in other ways. This is implemented for `LegacyScriptPubKeyMan` by moving key-to-destination code from `CWallet` to `LegacyScriptPubKeyMan`
* In order for `ScriptPubKeyMan` to be generic and work with future `ScriptPubKeyMan`s, `ScriptPubKeyMan::ReturnDestination` is changed to take a `CTxDestination` instead of a `CPubKey`. Since `LegacyScriptPubKeyMan` still deals with keys internally, a new map `m_reserved_key_to_index` is added in order to track the keypool indexes that have been reserved.
* A bug is fixed in how the total keypool size is calculated as it was omitting `set_pre_split_keypool` which is a bug.

In order for ScriptPubKeyMan to be generic and work with future

take a CTxDestination instead of a CPubKey. Since LegacyScriptPubKeyMan
still deals with keys internally, a new map m_reserved_key_to_index is
added in order to track the keypool indexes that have been reserved.
The CPubKey argument of KeepDestination is also removed so that it is
more generic. Instead of taking a CPubKey or a CTxDestination, we just use
the nIndex given to find the pubkey.
Addresses are determined by LegacyScriptPubKeyMan::GetReservedDestination
instead of ReserveDestination::GetReservedDestination as other ScriptPubKeyMan
implementations may construct addresses differently
This does not change behavior.
An opportunistic TopUp is moved from LegacyScriptPubKeyMan::GetNewDestination
to CWallet::GetNewDestination. Another opportunistic TopUp is moved from
LegacyScriptPubKeyMan::ReserveKeyFromKeyPool (called by LegacyScriptPubKeyMan::GetReservedDestination)
to ReserveDestination::GetReservedDestination.
Moving opportunistic TopUps ensures that ScriptPubKeyMans will always
be topped up before requesting Destinations from them as we cannot
always rely on future ScriptPubKeyMan implementaions topping up internally.
As such, it is also unnecessary to keep the TopUp calls in the
LegacyScriptPubKeyMan functions so they are moved.
This does not change behavior as TopUp calls are moved up the call stack.
This does not change behavior. This TopUp() is unnecessary as currently
m_spk_man calls TopUp further down the call stack inside

By removing this here, we also prepare for future changes where CWallet
has multiple ScriptPubKeyMans instead of m_spk_man.
Call LegacyScriptPubKeyMan::CanGetAddresses directly instead of calling
CWallet::CanGetAddresses to only query the relevant key manager
This is a minor change in behavior: call now only happens if a new key needs to
be reserved, since if a key is already reserved it might fail unnecessarily.
This change also serves as a sanity check

For example: During watch-only transaction creation, previous transaction in wallet, pubkey imported, but not the witnessscript associated with the prevout.
In this case I think no/minimal comment is better than specific and soon to be out of date.

3958295bc8 wallet: LearnRelatedScripts only if KeepDestination (João Barbosa)
55295fba4c wallet: Lock address type in ReserveDestination (João Barbosa)
Pull request description:
Only mutates the wallet if the reserved key is kept.
First commit is a refactor that makes the address type a class member.
The second commit moves `LearnRelatedScripts` from `GetReservedDestination` to `KeepDestination` to avoid an unnecessary call to `AddCScript` - which in turn prevents multiple entries of the same script in the wallet DB.

Pull request description:
For wallets with `WALLET_FLAG_DISABLE_PRIVATE_KEYS` this makes the watch-only balance available on the send screen (including coin selection). Instead of sending a transaction it generates a PSBT.
The user can take this PSBT and process it with [HWI](https://github.com/bitcoin-core/HWI) or put it an SD card for hardware wallets that support that.
The PSBT is copied to the clipboard. This was the easiest approach; we can add a dialog later to display it, as well as an option to save to disk.

Pull request description:
Work starter to remove Chain::Lock interface by adding m_last_block_processed_height in CWallet and m_block_height in CMerkleTx to avoid GetDepthInMainChain having to keep a lock . Once this one done, it should ease work to wipe out more cs_main locks from wallet code.
I think it's ready for a first round of review before to get further.
- `BlockUntilSyncedToCurrent` : restrain isPotentialTip to isTip because we want to be sure that wallet see BlockDisconnected callbacks if its height differs from the Chain one. It means during a reorg, an RPC could return before the BlockDisconnected callback had been triggered. This could cause a tx that had been included in the disconnected block to be displayed as confirmed, for example.
~~- `AbandonTransaction` : in case of conflicted tx (nIndex = -1), we set its m_block_height to the one of conflicting blocks, but if this height is superior to CWallet::m_last_block_processed_height, that means tx isn't conflicted anymore so we return 0 as tx is again unconfirmed~~ After #16624, we instead rely on Confirmation.
~~- `AddToWalletIfInvolvingMe`: in case of block disconnected, transactions are added to mempool again, so we need to replace old txn in `mapWallet` with a height set to zero so we remove check on block_hash.IsNull~~ Already done in #16624

We don't remove yet Chain locks as we need to preserve lock
order with CWallet one until swapping at once to avoid
deadlock failures (spotted by --enable-debug)
is exact match
In the next commit, we start using BlockConnected/BlockDisconnected
callbacks to establish tx depth, rather than querying the chain
directly.
Currently, BlockUntilSyncedToCurrentChain will return early if
the best block processed by the wallet is a descendant of the node'tip.
That means that in the case of a re-org, it won't wait for the
BlockDisconnected callbacks that have been enqueued during the re-org
but have not yet been triggered in the wallet.
Change BlockUntilSyncedToCurrentChain to only return early if the
wallet's m_last_block_processed matches the tip exactly. This ensures
that there are no BlockDisconnected or BlockConnected callbacks
in-flight.
At wallet loading, we rely on chain state querying to retrieve
height of txn, to do so we ensure that lock order is respected
between cs_main and cs_wallet.
If wallet loaded is the wallet-tool one, all wallet txn will
show up with a height of zero. It doesn't matter as confirmation
height is not used by wallet-tool.
Reorder arguments and document Confirmation calls to avoid
ambiguity.
Fixes nits left from #16624
To do so we update CValidationInterface::BlockDisconnect to take a
CBlockIndex pointing to the block being disconnected.
This new parameter will be use in the following commit to establish
wallet height.

dce032ce29 Make IsTrusted scan parents recursively (Jeremy Rubin)
Pull request description:
This slightly modifies the behavior of IsTrusted to recursively check the parents of a transaction. Otherwise, it's possible that a parent is not IsTrusted but a child is. If a parent is not trusted, then a child should not be either.
This recursive scan can be a little expensive, so ~it might be beneficial to have a way of caching IsTrusted state, but this is a little complex because various conditions can change between calls to IsTrusted (e.g., re-org).~ I added a cache which works per call/across calls, but does not store the results semi-permanently. Which reduces DoS risk of this change. There is no risk of untrusted parents causing a resource exploitation, as we immediately return once that is detected.
This is a change that came up as a bug-fix esque change while working on OP_SECURETHEBAG. You can see the branch where this change is important here: https://github.com/bitcoin/bitcoin/compare/master...JeremyRubin:stb-with-rpc?expand=1. Essentially, without this change, we can be tricked into accepting an OP_SECURETHEBAG output because we don't properly check the parents. As this was a change which, on its own, was not dependent on OP_SECURETHEBAG, I broke it out as I felt the change stands on its own by fixing a long standing wallet bug.
The test wallet_balance.py has been corrected to meet the new behavior. The below comment, reproduced, explains what the issue is and the edge cases that can arise before this change.
# Before `test_balance()`, we have had two nodes with a balance of 50
# each and then we:
#
# 1) Sent 40 from node A to node B with fee 0.01
# 2) Sent 60 from node B to node A with fee 0.01
#
# Then we check the balances:
#
# 1) As is
# 2) With transaction 2 from above with 2x the fee
#
# Prior to #16766, in this situation, the node would immediately report
# a balance of 30 on node B as unconfirmed and trusted.
#
# After #16766, we show that balance as unconfirmed.
#
# The balance is indeed "trusted" and "confirmed" insofar as removing
# the mempool transactions would return at least that much money. But
# the algorithm after #16766 marks it as unconfirmed because the 'taint'
# tracking of transaction trust for summing balances doesn't consider
# which inputs belong to a user. In this case, the change output in
# question could be "destroyed" by replace the 1st transaction above.
#
# The post #16766 behavior is correct; we shouldn't be treating those
# funds as confirmed. If you want to rely on that specific UTXO existing
# which has given you that balance, you cannot, as a third party
# spending the other input would destroy that unconfirmed.
#
# For example, if the test transactions were:
#
# 1) Sent 40 from node A to node B with fee 0.01
# 2) Sent 10 from node B to node A with fee 0.01
#
# Then our node would report a confirmed balance of 40 + 50 - 10 = 80
# BTC, which is more than would be available if transaction 1 were
# replaced.
The release notes have been updated to note the new behavior.

ScriptPubKeyMan is only using UnsetWalletFlagWithDB to unset the blank
wallet flag. Just make that it's own function and not expose the flag
writing directly.
This does not change behavior.
This moves CWallet members and methods dealing with keys to a new
LegacyScriptPubKeyMan class, and updates calling code to reference the new
class instead of CWallet.
Most of the changes are simple text replacements and variable substitutions
easily verified with:
git log -p -n1 -U0 --word-diff-regex=.
The only nontrivial chunk of code added is the new LegacyScriptPubKeyMan class
declaration, but this code isn't new and is just selectively copied and moved
from the previous CWallet class declaration. This can be verified with:
git log -p -n1 --color-moved=dimmed_zebra src/wallet/scriptpubkeyman.h src/wallet/wallet.h
or
git diff HEAD~1:src/wallet/wallet.h HEAD:src/wallet/scriptpubkeyman.h
This commit does not change behavior.
Start moving wallet and ismine code to scriptpubkeyman.h, scriptpubkeyman.cpp
The easiest way to review this commit is to run:
git log -p -n1 --color-moved=dimmed_zebra
And check that everything is a move (other than includes and copyrights comments).

ea4cc3a7b3 Truly decouple wallet from chainparams for -fallbackfee (Jorge Timón)
Pull request description:
Before it was 0 by default for main and 20000 for test and regtest.
Now it is 0 by default for all chains, thus there's no need to call Params().
Also now the default for main is properly documented.
Suggestion for release notes:
-fallbackfee was 0 (disabled) by default for the main chain, but 20000 by default for the test chains. Now it is 0 by default for all chains. Testnet and regtest users will have to add fallbackfee=20000 to their configuration if they weren't setting it and they want it to keep working like before.
Should I propose them to the wiki for the release notes or only after merge?

a31be09bfd Encapsulate tx status in a Confirmation struct (Antoine Riard)
Pull request description:
While working on #15931, I've tried to rationalize tx state management to ease integration of block height tracking per-wallet tx. We currently rely on a combination of `hashBlock` and `nIndex` with magic value to determine tx confirmation, conflicted or abandoned state. It's hard to reason and error-prone. To solve that, we encapsulate these fields in a `TxConfirmation` struct and introduce a `TxState` member that we update accordingly at block connection/disconnection.
Following jnewbery [recommendation](https://github.com/bitcoin/bitcoin/pull/15931#discussion_r312576506), I've taken these changes in its own commit, and open a PR to get them first. It would ease review of aforementioned PR, but above all should ease fixing of long-term issues like :
* https://github.com/bitcoin/bitcoin/issues/7315 (but maybe we should abandon abandontransaction or relieve it to only free outpoints not track the transaction as abandoned in itself, need its own discussion)
* https://github.com/bitcoin/bitcoin/issues/8692 where we should cancel conflicted state of transactions chain smoothly
* `MarkConflicted` in `LoadToWallet` is likely useless if we track conflicts rights at block connection
Main changes of this PR to get right are tx update in `AddToWallet` and serialization/deserialization logic.

in main chain. If not, we set its status to unconfirmed and reset
its hashBlock/nIndex.
If wallet loaded is the wallet-tool one, all wallet txn will
show up with a height of zero. It doesn't matter as status is not
used by wallet-tool.
We take lock prematurely in CWallet::LoadWallet and CWallet::Verify
to ensure that lock order is respected between cs_main an cs_wallet.
The function ExtractPubKey() checks if a given script matches the P2PK pattern
(<PubKey> OP_CHECKSIG), extracts the PubKey and additionally checks if it is
cryptographically valid (full validation with ECC library via .IsFullyValid()).
Currently this is done manually in the following order:
1) check if first script OP is data push with valid PubKey length
(first part of pattern match), extract PubKey
2) create CPubKey object with extracted PubKey
3) fully validate public key
4) check if last script OP is OP_CHECKSIG
(second part of pattern match)
Using Solver, the pattern matching and PubKey extraction can be done via a
single step, leading to the following simplified order with shorter code:
1) check if given script matches P2PK pattern with Solver
(also contains valid PubKey length check), extracts Pubkey
2) create CPubKey object with extracted Pubkey
3) fully validate public key
Translated strings should not end up in the debug log, stderr, or
returned by an RPC.
Changing the util methods in util/error to return a bilingual_str paves
the way to achieve this goal in the long term.
We shouldn't rely on this sync call to get an accurate view of txn
state, if a tx conflicts with one in mapTx we are going to update
our wallet dependencies in AddToWalletIfInvolvingMe while conflicting
txn get connected. If it doesn't conflict with one of our dependencies
we are not going to track it anyway.
This is a cleanup, as this SyncTransaction is redundant with the
following one for confirmation which is triggering the MarkConflicted
logic. We keep the loop because set of conflicted txn isn't same as txn
included in block.
Instead of relying on combination of hashBlock and nIndex
values to manage tx in its lifecycle, we introduce 4
status : CONFIRMED, UNCONFIRMED, CONFLICTED, ABANDONED.
hashBlock and nIndex magic values should only be used at
serialization/deserialization for backward-compatibility.
At block disconnection, we know flag txn as UNCONFIRMED where
previously they kept their states until being override by a
block connection or abandontransaction call. This is a change
in behavior for which user may have to call abandon twice
if transaction is disconnected and not accepted back in the mempool.
We assert status transitioning right in AddToWallet. Doing so
flagged a misbehavior in ComputeTimeSmart unit test where same
tx is confirmed twice in different block. To avoid inconsistencies
we unconfirmed tx before new connection in different block. We
also remove a cs_main lock in test, as AddToWallet and its
callees don't rely on locked chain.
Restores the confirmed/conflicted tx check removed in
8753f5652b. There should be no external
behaviour change (these txs would not get accepted to the mempool
anyway), but not having the check in the wallet causes log spam.
Also adds a comment to ResentWalletTransactions() that
confirmed/conflicted tx check is done in SubmitMemoryPoolAndRelay().
IsCoinBase check is already performed early by
AcceptToMemoryPoolWorker
GetDepthInMainChain check is already perfomed by
BroadcastTransaction
To avoid deadlock we MUST keep lock order in
ResendWalletTransactions and CommitTransaction,
even if we lock cs_main again further.
in BroadcastTransaction. Lock order will need
to be clean at once in a future refactoring

e10e1e8db0 Restrict lifetime of ReserveDestination to CWallet::CreateTransaction (Gregory Sanders)
d9ff862f2d CreateTransaction calls KeepDestination on ReserveDestination before success (Gregory Sanders)
Pull request description:
The typical usage pattern of `ReserveDestination` is to explicitly `KeepDestination`, or `ReturnDestination` when it's detected it will not be used.
Implementers such as myself may fail to complete this pattern, and could result in key re-use: https://github.com/bitcoin/bitcoin/pull/15557#discussion_r271956393
Since ReserveDestination is currently only used directly in the `CreateTransaction`/`CommitTransaction` flow(or fee bumping where it's just used in `CreateTransaction`), I instead make the assumption that if a transaction is returned by `CreateTransaction` it's highly likely that it will be accepted by the caller, and the `ReserveDestination` kept. This simplifies the API as well. There are very few cases where this would not be the case which may result in keys being burned.
Those failure cases appear to be:
`CommitTransaction` failing to get the transaction into the mempool
Belt and suspenders check in `WalletModel::prepareTransaction`

The internal bool was only to indicate whether the given label should
be applied as things that are internal should not have a label. To make
this clearer, we change internal to apply_label and invert its usage
so things that have labels set this to true in order to have their labels
applied.

1b699a5083 Add HaveKey and HaveCScript to SigningProvider (Andrew Chow)
Pull request description:
This PR compresses the `CWallet` chain of inheritance from 5 classes to 3 classes. `CBasicKeyStore` is renamed to `FillableSigningProvider` and some parts of it (the watchonly parts) are moved into `CWallet`. `CKeyStore` and `CCrypoKeyStore` are completely removed. `CKeyStore`'s `Have*` functions are moved into `SigningProvider` and the `Add*` moved into `FillableSigningProvider`, thus allowing it to go away entirely. `CCryptoKeyStore`'s functionality is moved into `CWallet`. The new inheritance chain is:
```
SigningProvider -> FillableSigningProvider -> CWallet
```
`SigningProvider` now is the class the provides keys and scripts and indicates whether keys and scripts are present. `FillableSigningProvider` allows keys and scripts to be added to the signing provider via `Add*` functions. `CWallet` handles all of the watchonly stuff (`AddWatchOnly`, `HaveWatchOnly`, `RemoveWatchOnly` which were previously in `CKeyStore`) and key encryption (previously in `CCryptoKeyStore`).
Implements the 2nd [prerequisite](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes#cwallet-subclass-stack) from the wallet restructure.

Pull request description:
The wallet should give out destinations instead of keys. It should be the one that handles the conversion from key to destination and the setting of the label, not the caller.

Additionally, `CReserveKey` is changed to be `ReserveDestination` and represents destinations whose keys can be returned to the keypool.
