72a9540df9 Implement FillPSBT in DescriptorScriptPubKeyMan
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.

Merge #17219: wallet: allow transaction without change if keypool is empty
92bcd70808 [wallet] allow transaction without change if keypool is empty (Sjors Provoost)
709f8685ac [wallet] CreateTransaction: simplify change address check (Sjors Provoost)
5efc25f963 [wallet] translate "Keypool ran out" message (Sjors Provoost)

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.

wallet: Prefer full destination groups in coin selection
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.

b86cd155f6 scripted-diff: Wallet: Rename mapAddressBook to m_address_book (Luke Dashjr)

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.

48973402d8 wallet: Avoid use of Chain::Lock in CWallet::GetKeyBirthTimes

locking.

This change only affects behavior in the case where wallet last block processed

c0d07dc4cb wallet: Avoid use of Chain::Lock in CWallet::ScanForWalletTransactions
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

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 change only affects behavior in the case where wallet last block processed

will just be stricter in this case and only accept values up to the last
processed height

ab31b9d6fe Fix wallet unload race condition
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.
