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.
Fixes#14995 , fixes#18482. Best reviewed with whitespace changes hidden.

cd3b1569d9 Correctly compute redeemScript from witnessScript for signrawtransaction (Andrew Chow)
Pull request description:
`ParsePrevouts` uses `GetScriptForWitness` on the given witnessScript to find the corresponding redeemScript. This is incorrect when the witnessScript is either a P2PK or P2PKH script as it returns the corresponding P2WPK script instead of turning the witnessScript into a P2WSH script. Instead this should make the script a `WitnessV0ScriptHash` destination and get the script for that.
Test cases are also added. These will fail on master with a `redeemScript does not correspond to witnessScript`

f65c9ad40f Check for overflow when calculating sum of outputs (Elichai Turkel)
Pull request description:
This was reported by practicalswift here #18046
The exact order of the if, is important, we first do `!MoneyRange(tx_out.nValue)` to make sure the amount is non-negative. and then `std::numeric_limits<CAmount>::max() - tx_out.nValue < nValueOut` checks that the addition cannot overflow (if we won't check that the amount is positive this check can also overflow! (by doing something like `max - -max`))
and only then we make sure that the some is also valid `!MoneyRange(nValueOut + tx_out.nValue)`
if any of these conditions fail we throw.
the overflowing logic:
```
a + b > max // we want to fail if a+b is more than the maximum -> will overflow
b > max - a
max - a < b

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 change affects behavior in a few small ways.
- If there's no max_height specified, percentage progress is measured ending at

41b0baf43c gui: Handle WalletModel::unload asynchronous (João Barbosa)
ab31b9d6fe Fix wallet unload race condition (Russell Yanofsky)
Pull request description:
This PR consists in two fixes. The first fixes a concurrency issues with `boost::signals2`. The second fixes a wallet model destruction while it's being used.
From boost signal documentation at https://www.boost.org/doc/libs/1_72_0/doc/html/signals2/thread-safety.html:
> When a signal is invoked by calling signal::operator(), the invocation first acquires a lock on the signal's mutex. Then it obtains a handle to the signal's slot list and combiner. Next it releases the signal's mutex, before invoking the combiner to iterate through the slot list.
This means that `UnregisterValidationInterface` doesn't prevent more calls to that interface. The fix consists in capturing the `shared_ptr<CValidationInterface>` in each internal slot.
The GUI bug is fixed by using a `Qt::QueuedConnection` in the `WalletModel::unload` connection.

0933a37078 gui: Avoid Wallet::GetBalance in WalletModel::pollBalanceChanged (João Barbosa)
Pull request description:
Each 250ms the slot `WalletModel::pollBalanceChanged` is called which, at worst case, calls `Wallet::GetBalance`. This is a waste of resources since most of the time there aren't new transactions or new blocks. Fix this by early checking if cache is dirty or not.

e980214bc4 serialization: prevent int overflow for big Coin::nHeight (pierrenn)
Pull request description:
This is an attempt to fix fuzzer issues 1,2,8 reported by practicalswift here : https://github.com/bitcoin/bitcoin/issues/18046
The fuzzer harness doesn't prevent deserialization of unrealistic high values for `Coin::nHeight`. In the [provided examples](https://github.com/bitcoin/bitcoin/issues/18046), we have :
- `blockundo_deserialize` : the varint `0x8DD88DD700` is deserialized as `3944983552` in `Coin::nHeight` (`TxInOutFormatter::Unser`)
- `coins_deserialize` : the varint `0x8DD5D5EC40` is deserialized as `3939874496` similarly
- `txundo_deserialize`: the varint `0x8DCD828F01` is deserialized as `3921725441` in `Coin::nHeight` (`Coin::Unserialize`)
Since `Coin::nHeight` is 31 bit long, multiplying a large value by 2 triggers the fuzzer.
AFAIK those values are unrealistic (~70k years for the smallest..). I've looked a bit a reducing the range of values the fuzzer can deserialize, but this seems to be too much code change for not much.
Hence this PR chooses to static cast `nHeight` when re-serializing; it seems to be the less intrusive/safest way to prevent the fuzzer output.
Another more "upstream" approach would be to limit `Coin::nHeight` values to something more realistic, e.g. `0xFFFFFFF` (~5k years) :
de3a30bab2/src/undo.h (L39) and de3a30bab2/src/coins.h (L71)

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.
ef35604c9c rpc: fix broken RPCExamples for waitforblock(height) (Sebastian Falbesoner)
Pull request description:
This PR fixes several broken RPCExamples from the "blockchain" category:
- `HelpExampleCli` for `waitforblock` (disturbing comma between arguments)
- `HelpExampleCli` for `waitforblockheight` (disturbing comma between arguments)
- `HelpExampleRpc` for `waitforblockheight` (disturbing quotation marks around integer argument)
Note that the CLI example for `waitforblockheight` would also work with the first argument in quotation marks (in contrast to the RPC example), but I removed them as well as they are not needed.
Outputs for the non-working examples in the master branch:

9ab14e4d21 Limit decimal range of numbers ParseScript accepts (pierrenn)
Pull request description:
Following up on this suggestion : https://github.com/bitcoin/bitcoin/pull/18413#issuecomment-602966490, prevent the output of `atoi64` in the `core_read.cpp:ParseScript` helper to send to `CScriptNum::serialize` values wider than 32-bit.
Since the `ParseScript` helper is only used by the tool defined in `bitcoin-tx.cpp`, this only prevents users to provide too much unrealistic values.
