a1d5b12ec0 Merge getreceivedby tally into GetReceived function (Andrew Toth)
Pull request description:
This PR merges the tally code of `getreceivedbyaddress` and `getreceivedbylabel` into a single function `GetReceived`. This reduces repeated code and makes it similar to `listreceivedbyaddress` and `listreceivedbylabel`, which use the function `ListReceived`. It will also make the change in #14707 simpler and easier to review.

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:
This fixes a bug found with #18531:
* Currently the named argument for `generateblock` is documented as `address/descriptor`, but the server only accepts a named argument of `address`. Fix it by changing the name to `output` for both the documentation and the server code. Also, add tests to prove the server understands the new name `output`.
* Unrelated to that, there have been a bunch of aliases in the server code that are not present in the source code of the documentation. Fix that by adding the alias to the source code of the documentation. Only the first alias is displayed in the rendered documentation. Also, add tests to prove the server actually understands all aliases.

38677274f9 rpc: settxfee respects -maxtxfee wallet setting (Fabian Jahr)
bda84a08a0 rpc: Add documentation for deactivating settxfee (Fabian Jahr)
Pull request description:
~~Closes 18315~~
`settxfee` can be deactivated by passing 0 as the fee. That does not seem to be documented for the user so this PR adds it in the description. The return value of a simple boolean seems also too simplified given the multiple dimensions that this deactivation feature enables. I.e. it does not seem intuitive if the returned boolean shows that the call succeeded or if means that `settxfee` is active. My suggested solution is to change the return value to a JSON object that included the "active" state and the currently set fee rate.
Examples:
```
$ src/bitcoin-cli settxfee 0.0000000
{
"active": false,
"fee_rate": "0.00000000 BTC/kB"
}
$ src/bitcoin-cli settxfee 0.0001
{
"active": true,
"fee_rate": "0.00010000 BTC/kB"
}
```

Pull request description:
This fixes compile errors trying to build bitcoin-tx and bitcoin-wallet without libevent, which were reported by Luke Dashjr in https://github.com/bitcoin/bitcoin/issues/18465
The fix avoiding `bitcoin-tx` dependency on libevent just adds a conditional build rule. This is implemented in the first commit (more details in commit description).
The fix avoiding `bitcoin-wallet` dependency on libevent requires minor code changes, because `bitcoin-wallet` (unlike `bitcoin-tx`) links against code that calls `urlDecode` / `evhttp_uridecode`. This fix is implemented in the second commit (again details in the commit description).

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`.

7b8e15728d rpc: Fix rpcRunLater race in walletpassphrase (João Barbosa)
Pull request description:
Release locks before calling `rpcRunLater`.
Quick explanation: `rpcRunLater` leads to `event_free` which calls `event_del` which can wait for the event callback to finish if it's already running and that callback will try to lock wallet mutex - which is already locked in http thread.

Previous versions assumed absence of an entry in mapAddressBook indicated change.
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.
-BEGIN VERIFY SCRIPT-
sed -i -e 's/mapAddressBook/m_address_book/g' $(git grep -l 'mapAddressBook' ./src)
-END VERIFY SCRIPT-
Don't require urlDecode function in wallet code since urlDecode implementation
currently uses libevent. Just call urlDecode indirectly though URL_DECODE
function pointer constant if available.
In bitcoind and bitcoin-qt, URL_DECODE is implemented and used to interpret RPC
wallet requests. In bitcoin-wallet, URL_DECODE is null to avoid depending on
libevent.
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 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
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. Previously listsinceblock might not have returned
all transactions up to the claimed "lastblock" value in this case, resulting in
race conditions and potentially missing transactions in cases where
listsinceblock was called in a loop like
https://github.com/bitcoin/bitcoin/issues/14338#issuecomment-426706574
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.

2c52b59d0a Refactor rawtransaction's SignTransaction into generic SignTransaction function (Andrew Chow)
Pull request description:
Following #17261, the way to sign transactions, PSBTs, and messages was to use `GetSigningProvider()` and get a `SigningProvider` containing the private keys. However this may not be feasible for future `ScriptPubKeyMan`s, such as for hardware wallets. Instead of exporting a `SigningProvider` containing private keys, we need to pass these things into the `ScriptPubKeyMan` (via `CWallet`) so that they can do whatever is needed internally to sign them. This is largely a refactor as the logic of processing transactions, PSBTs, and messages for is moved into `LegacyScriptPubKeyMan` and `CWallet` instead of being handled by the caller (e.g. `signrawtransaction`).
To help with this, I've refactored the 3(!) implementations of a `SignTransaction()` function into one generic one. This function will be called by `signrawtransactionwithkey` and `LegacyScriptPubKeyMan::SignTransaction()`. `CWallet::CreateTransaction()` is changed to call `CWallet::SignTransaction()` which in turn, calls `LegacyScriptPubKeyMan::SignTransaction()`. Other `ScriptPubKeyMan`s may implement `SignTransaction()` differently.
`FillPSBT()` is moved to be a member function of `CWallet` and the `psbtwallet.cpp/h` files removed. It is further split so that `CWallet` handles filling the UTXOs while the `ScriptPubKeyMan` handles adding keys, derivation paths, scripts, and signatures. In the end `LegacyScriptPubKeyMan::FillPSBT` still calls `SignPSBTInput`, but the `SigningProvider` is internal to `LegacyScriptPubKeyMan`. Other `ScriptPubKeyMan`s may do something different.
A new `SignMessage()` function is added to both `CWallet` and `ScriptPubKeyMan`. Instead of having the caller (i.e. `signmessage` or the sign message dialog) get the private key, hash the message, and sign, `ScriptPubKeyMan` will now handle that (`CWallet` passes through to the `ScriptPubKeyMan`s as it does for many functions). This signing code is thus consolidated into `LegacyScriptPubKeyMan::SignMessage()`, though other `ScriptPubKeyMan`s may implement it differently. Additionally, a `SigningError` enum is introduced for the different errors that we expect to see from `SignMessage()`.
Lastly, `GetSigningProvider()` is renamed to `GetPublicSigningProvider()`. It will now only provide pubkeys, key origins, and scripts. `LegacySigningProvider` has it's `GetKey` and `HaveKey` functions changed to only return false. Future implementations should return `HidingSigningProvider`s where private keys are hidden.
Other things like `dumpprivkey` and `dumpwallet` are not changed because they directly need and access the `LegacyScriptPubKeyMan` so are not relevant to future changes.

Pull request description:
A lot of places refer to `CWallet*`'s as `CWallet * const`, which translates to *"an immutable pointer to a mutable `CWallet` instance"*; this is
1. often not what the author meant, especially as a lot of these places do not at all modify the wallet object, and
2. confusing, as it tends to suggest that this is a proper way to refer to a constant `CWallet` instance.
This PR changes references to wallets to `const CWallet* const` whenever immutability is expected. This should result in no behavioral changes at all, and improved compile-time error checking.
Note from irc:
> <sipa> sounds good to me; this is the sort of change that as long as it compiles, the behavior shouldn't change
> <sipa> though in general it may lead to introducing automatic copying of objects sometimes (e.g. trying to std::move a const object will work, but generally result in a copy rather than an efficient move)
> <sipa> CWallet objects aren't copied or moved though
