UniValue does not have a constructor for enum values, however the
compiler will decay the enum into an int and select that constructor.
Avoid this compiler magic and clarify the code by explicitly selecting
the int-constructor.
This is needed for the next commit.

This should not change behavior and makes the code consistent with other
places.

fa8a1c06961f4b1826696e0db8dce81dce627721 rpc: Fix Univalue push_backV OOM in listtransactions (MacroFake)
Pull request description:
Related to, but not intended as a fix for #25229.
Currently the RPC will have the same data stored thrice:
* `UniValue ret` (memory filled by `ListTransactions`)
* `std::vector<UniValue> vec` (constructed by calling `push_backV`)
* `UniValue result` (the actual result, memory filled by `push_backV`)
Fix this by filling the memory only once:
* `std::vector<UniValue> ret` (memory filled by `ListTransactions`)
* Pass iterators to `push_backV` instead of creating a full copy
* Move memory into `UniValue result` instead of copying it

7a45c33d1f8a758850cf8e7bd6ad508939ba5c0d Introduce generic 'Result' class (furszy)
Pull request description:
Based on a common function signature pattern that we have all around the sources:
```cpp
bool doSomething(arg1, arg2, arg3, arg4, &result_obj, &error_string) {
// do something...
if (error) {
error_string = "something bad happened";
return false;
}
result = goodResult;
return true;
}
```
Introduced a generic class `BResult` that encapsulate the function boolean result, the result object (in case of having it) and, in case of failure, the string error reason.
Obtaining in this way cleaner function signatures and removing boilerplate code:
```cpp
BResult<Obj> doSomething(arg1, arg2, arg3, arg4) {
// do something...
if (error) return "something bad happened";
return goodResult;
}
```
Same cleanup applies equally to the function callers' side as well. There is no longer need to add the error string and the result object declarations before calling the function:
Before:
```cpp
Obj result_obj;
std::string error_string;
if (!doSomething(arg1, arg2, arg3, arg4, result_obj, error_string)) {
LogPrintf("Error: %s", error_string);
}
return result_obj;
```
Now:
```cpp
BResult<Obj> op_res = doSomething(arg1, arg2, arg3, arg4);
if (!op_res) {
LogPrintf("Error: %s", op_res.GetError());
}
return op_res.GetObjResult();
```
### Initial Implementation:
Have connected this new concept to two different flows for now:
1) The `CreateTransaction` flow. --> 7ba2b87c
2) The `GetNewDestination` flow. --> bcee0912
Happy note: even when introduced a new class into the sources, the amount of lines removed is almost equal to added ones :).
Extra note: this work is an extended version (and a decoupling) of the work that is inside #24845 (which does not contain the `GetNewDestination` changes nor the inclusion of the `FeeCalculation` field inside `CreatedTransactionResult`).

Pull request description:
### Context
The wallet's `m_address_book` field is being accessed directly from several places across the sources.
### Problem
Code structure wise, we shouldn't be accessing it directly. It could end up being modified by mistake (from a place that has nothing to do with the wallet like an RPC command or the GUI) and cause a bigger issue: like an address book entry 'purpose' string change, which if done badly (from 'send' to 'receive'), could end up in a user sharing a "receive" address that he/she doesn't own.
### Solution
Encapsulate `m_address_book` access inside the wallet.
-------------------------------------------------------
Extra Note:
This is the initial step towards decoupling the address book functionality from the wallet's sources. In other words, the creation of the `AddressBookManager` (which will be coming in a follow-up PR).

Seeking to make the `CoinControl` option less confusing/redundant.
In #16377 the `CoinControl` flag ‘m_add_inputs’ was added to tell the coin filtering and selection process two things:
- Coin Filtering: Only use the provided inputs. Skip the Rest.
- Coin Selection: Search the wtxs-outputs and append all the `CoinControl` selected outpoints to the selection result (skipping all the available output checks). Nothing else.
Meanwhile, in `CoinControl` we already have a flag ‘fAllowOtherInputs’ which is already saying:
- Coin Filtering: Only use the provided inputs. Skip the Rest.
- Coin Selection: If false, no selection process -> append all the `CoinControl` selected outpoints to the selection result (while they passed all the `AvailableCoins` checks and are available in the 'vCoins' vector).
As can notice, the first point in the coin filtering process is duplicated in the two option flags. And the second one, is slightly different merely because it takes into account whether the coin is on the `AvailableCoins` vector or not.
So it makes sense to merge ‘m_add_inputs’ and ‘fAllowOtherInputs’ into a single field for the coin filtering process while introduce other changes to add the missing/skipped coins into 'vCoins' vector if they were manually selected by the user (follow-up commits).

4ce235ef8f9a9dddc52d7ab60c8f71bda1d38873 wallet: return 'CoinsResult' struct in `AvailableCoins` (furszy)
Pull request description:
This started in #24845 but grew out of scope of it.
So, points tackled:
1) Avoid extra `GetWalletTx` lookups inside `AvailableCoins -> IsSpentKey`.
`IsSpentKey` was receiving the tx hash and index to internally lookup the tx inside the wallet's map. As all the `IsSpentKey` function callers already have the wtx available, them can provide the `scriptPubKey` directly.
2) Most of the time, we call `Wallet::AvailableCoins`, and later on the process, skip the non-spendable coins from the result in subsequent for-loops. So to speedup the process: introduced the ability to filter by "only_spendable" coins inside `Wallet::AvailableCoins` directly.
(the non-spendable coins skip examples are inside `AttemptSelection->GroupOutputs` and `GetAvailableBalance`).
4) Refactored `AvailableCoins` in several ways:
a) Now it will return a new struct `CoinsResult` instead of receiving the vCoins vector reference (which was being cleared at the beginning of the method anyway). --> this is coming from #24845 but cherry-picked it here too to make the following commits look nicer.
b) Unified all the 'wtx.tx->vout[I]' calls into a single call (coming from this comment https://github.com/bitcoin/bitcoin/pull/24699#discussion_r854163032).
5) The wallet `IsLockedCoin` and `IsSpent` methods now accept an `OutPoint` instead of a hash:index. Which let me cleanup a bunch of extra code.
6) Speeded up the wallet 'GetAvailableBalance': filtering `AvailableCoins` by spendable outputs only and using the 'AvailableCoins' retrieved `total_amount` instead of looping over all the retrieved coins once more.
-------------------------------------------------------
Side topic, all this process will look even nicer with #25218

p2sh-segwit in createmultisig
3a9b9bb38e653c8ff7220b9af6e337a90c2c22dc test: ensure createmultisig and addmultisigaddress are not returning any warning for expected cases (brunoerg)
eaf6f630c0190c634b5f1c85f749437f4209cc36 rpc: fix inappropriate warning for address type p2sh-segwit in createmultisig and addmultisigaddress (brunoerg)
Pull request description:
Fixes #25127
If there are any uncompressed keys when calling `AddAndGetMultisigDestination`, it will just default to a legacy address regardless of the chosen `address_type`. So, #23113 added a warnings field which will warn the user why their address format is different.
However, when creating a multisig (p2sh-segwit), it is returning an inappropriate warning, because when getting the output type from destination (`OutputTypeFromDestination`), it returns `ScriptHash` for both legacy and `P2SH_SEGWIT`. So, since `P2SH_SEGWIT` is different from `ScriptHash`, it returns the warning:
https://github.com/bitcoin/bitcoin/blob/192d639a6b1bd0feaa52e6ea4e63e33982704c32/src/rpc/output_script.cpp#L166-L169
So, to avoid this mistake I changed `OutputTypeFromDestination` to `descriptor->GetOutputType()` to get the appropriate output type.

Pull request description:
In non-test/benchmarking code, there are three cases of the `NO_THREAD_SAFETY_ANALYSIS` annotation which are accompanied with `TODO` comments.
This PR adds proper thread safety annotations instead of `NO_THREAD_SAFETY_ANALYSIS`.

CreateTransaction() as optional struct
4c5ceb040cf50d24201903a9200fb23be88d96fb wallet: CreateTransaction(): return out-params as (optional) struct (Sebastian Falbesoner)
c9fdaa5e3ae09b45be6a5c2d4ee6b1e8cef9d8a8 wallet: CreateTransactionInternal(): return out-params as (optional) struct (Sebastian Falbesoner)
Pull request description:
The method `CWallet::CreateTransaction` currently returns several values in the form of out-parameters:
* the actual newly created transaction (`CTransactionRef& tx`)
* its required fee (`CAmount& nFeeRate`)
* the position of the change output (`int& nChangePosInOut`) -- as the name suggests, this is both an in- and out-param
By returning these values in an optional structure (which returns no value a.k.a. `std::nullopt` if an error occured), the interfaces is shorter, cleaner (requested change position is now in-param and can be passed by value) and callers don't have to create dummy variables for results that they are not interested in.
Note that the names of the replaced out-variables were kept in `CreateTransactionInternal` to keep the diff minimal. Also, the fee calculation data (`FeeCalculation& fee_calc_out`) would be another candidate to put into the structure, but `FeeCalculation` is currently an opaque data type in the wallet interface and I think it should stay that way.
As a potential follow-up, I think it would make sense to also do the same refactoring for `CWallet::FundTransaction`, which has a very similar parameter structure.

f336ff7f213564909cf5f9742618cc6ec87600fd rpc: avoid expensive `IsMine` calls in `GetReceived` tally (Sebastian Falbesoner)
a7b65af2a4450663d4a20a617c59dac87b34fb36 rpc: avoid scriptPubKey<->CTxDestination conversions in `GetReceived` tally (Sebastian Falbesoner)
Pull request description:
The RPC calls `getreceivedbyaddress`/`getreceivedbylabel` both use the internal helper function `GetReceived` which was introduced in PR #17579 to deduplicate tallying code. For every wallet-related transaction output, the following unnecessary operations are currently performed in the tally loop, leading to a quite bad performance (as reported in #23645):
- converting from CScript -> TxDestination (`ExtractDestination(...)`), converting from TxDestination -> CScript (`CWallet::IsMine(const CTxDestination& dest)`); this can be avoided by directly using output scripts in the search set instead of addresses (first commit)
- checking if the iterated output script belongs to the wallet by calling `IsMine`; this can be avoided by only adding addresses to the search set which fulfil `IsMine` in the first place (second commit)
### Benchmark results
The functional test [wallet_pr23662.py](https://github.com/theStack/bitcoin/blob/pr23662_benchmarks/test/functional/wallet_pr23662.py) (not part of this PR) creates transactions with 15000 different addresses:
- 5000 outputs (500 txs with 10 outputs each) with label set, IsMine set (received)
- 5000 outputs (500 txs with 10 outputs each) with label set, IsMine not set (sent)
- 5000 outputs (500 txs with 10 outputs each) without label set, IsMine not set (sent)
Then, the time is measured for calling `getreceivedbyaddress` and `getreceivedbylabel`, the latter with two variants. Results on my machine:
| branch | `getreceivedbyaddress` (single) | `getreceivedbylabel` (single) | `getreceivedbylabel` (10000) |

Fixes #23645.

4637bbe448ae7370528f40092ce230c32602a6d6 rpc: Explain active and internal in listdescriptors (Andrew Chow)
Pull request description:
The current help text for active and internal in listdescriptors is not particularly helpful. They require the reader to already know what those terms mean. This help text is updated to actually explain the definitions of those words in context of a descriptor wallet.
