fa66e2d07a4b87d62382a54acf5fab6af77be24e refactor: [rpc] Remove confusing and brittle integral casts (MarcoFalke)

Pull request description:

  When constructing an UniValue from integral values, historically (long ago), in some cases casts where needed. With the current UniValue constructor, only very few are actually needed.

  Keeping the unused casts around is:

  * confusing, because code readers do not understand why they are needed
  * brittle, because some may copy them into new places, where they will lead to hard-to-find logic bugs, such as the ones fixed in pull https://github.com/bitcoin/bitcoin/pull/34112

  So fix all issues by removing them, except for a few cases, where casting was required:
  * `ret.pushKV("coinbase", static_cast<bool>(coin->fCoinBase));`, or
  * `static_cast<std::underlying_type_t<decltype(info.nServices)>>(info.nServices)`.

  This hardening refactor does not fix any bugs and does not change any behavior.

fa5f29774872d18febc0df38831a6e45f3de69cc scripted-diff: [doc] Unify stale copyright headers (MarcoFalke)

Pull request description:

  Historically, the upper year range in file headers was bumped manually
  or with a script.

  This has many issues:

  * The script is causing churn. See for example commit 306ccd4, or
    drive-by first-time contributions bumping them one-by-one. (A few from
    this year: https://github.com/bitcoin/bitcoin/pull/32008,
    https://github.com/bitcoin/bitcoin/pull/31642,
    https://github.com/bitcoin/bitcoin/pull/32963, ...)
  * Some, or likely most, upper year values were wrong. Reasons for
    incorrect dates could be code moves, cherry-picks, or simply bugs in
    the script.
  * The upper range is not needed for anything.
  * Anyone who wants to find the initial file creation date, or file
    history, can use `git log` or `git blame` to get more accurate
    results.
  * Many places are already using the `-present` suffix, with the meaning
    that the upper range is omitted.

  To fix all issues, this bumps the upper range of the copyright headers
  to `-present`.

  Further notes:

  * Obviously, the yearly 4-line bump commit for the build system (c.f.
    b537a2c02a9921235d1ecf8c3c7dc1836ec68131) is fine and will remain.
  * For new code, the date range can be fully omitted, as it is done
    already by some developers. Obviously, developers are free to pick
    whatever style they want. One can list the commits for each style.
  * For example, to list all commits that use `-present`:
    `git log --format='%an (%ae) [%h: %s]' -S 'present The Bitcoin'`.
  * Alternatively, to list all commits that use no range at all:
    `git log --format='%an (%ae) [%h: %s]' -S '(c) The Bitcoin'`.

  <!--
  * The lower range can be wrong as well, so it could be omitted as well,
    but this is left for a follow-up. A previous attempt was in
    https://github.com/bitcoin/bitcoin/pull/26817.

refactor: unify container presence checks - trivial counts
The changes made here were:

| From              | To               |
|-------------------|------------------|
| `m.count(k)`      | `m.contains(k)`  |
| `!m.count(k)`     | `!m.contains(k)` |
| `m.count(k) == 0` | `!m.contains(k)` |
| `m.count(k) != 0` | `m.contains(k)`  |
| `m.count(k) > 0`  | `m.contains(k)`  |

The commit contains the trivial, mechanical refactors where it doesn't matter if the container can have multiple elements or not

rpc: refactor: use string_view in Arg/MaybeArg
Modernizes interface by not forcing users to deal with raw pointers,
without adding copying overhead. Generalizes the logic of whether
we return by value or by optional/pointer.

In cases where functions take a `const std::string&` and it would
be too much work to update them, a string copy is made (which was
already happening anyway).

6a7aa01574 wallet: Remove COutput::spendable and AvailableCoinsListUnspent
In descriptor wallets, we consider all outputs to be spendable as we no
longer have mixed mine and watchonly in a wallet. As such,
COutput::spendable is meaningless and can be removed.

Furthermore, CoinFilterParams::only_spendable can be removed as that was
essentially checking for COutput::spendable.

Lastly, AvailableCoinsListUnspent can also be removed as the wrapper is
now only setting the feerate to std::nullopt which is trivial enough that
a dedicated wrapper is not needed.

Merge bitcoin/bitcoin#32593: wallet, rpc: Move (Un)LockCoin WalletBatch creation out of RPC
6135e0553e6e58fcf506700991fa178f2c50a266 wallet, rpc: Move (Un)LockCoin WalletBatch creation out of RPC (Ava Chow)

Pull request description:

  If the locked coin needs to be persisted to the wallet database, insteead of having the RPC figure out when to create a WalletBatch and having LockCoin's behavior depend on it, have LockCoin take whether to persist as a parameter so it makes the batch.

  Since unlocking a persisted locked coin requires a database write as well, we need to track whether the locked coin was persisted to the wallet database so that it can erase the locked coin when necessary.

  Keeping track of whether a locked coin was persisted is also useful information for future PRs.

Pull request description:

  Allow RPC methods which take an `options` parameter (`importmulti`, `listunspent`, `fundrawtransaction`, `bumpfee`, `send`, `sendall`, `walletcreatefundedpsbt`, `simulaterawtransaction`), to accept the options as named parameters, without the need for nested JSON objects.

  This makes it possible to make calls like:

  ```sh
  src/bitcoin-cli -named bumpfee txid fee_rate=10
  ```

  instead of

  ```sh
  src/bitcoin-cli -named bumpfee txid options='{"fee_rate": 10}'
  ```

  RPC help is also updated to show options as top level named arguments instead of as nested objects.

  **Review suggestion:** To understand this PR, it is probably easiest to review the commits in reverse order because the last commit shows the external API changes, the middle commit shows the internal API changes, and the first commit contains the low-level implementation.

Pull request description:

  This PR is to address follow-ups for #24584, specifically:

  * Remove redundant, hard-to-read code by adding a new `OutputType` and adding shuffle, erase, and push_back methods for `CoinsResult`
  * Add missing `BOOST_ASSERT` to unit test
  * Ensure functional test only runs if using descriptor wallets
  * Improve readability of `AttemptSelection` by removing triple-nested if statement

  Note for reviewers: commit `refactor: add new helper methods` should throw an "unused function warning"; the function is used in the next commit. Also, commit `wallet: switch to new shuffle, erase, push_back` will fail to compile, but this is fixed in the next commit with a scripted-diff. the commits are separate like this (code change then scripted-diff) to improve legibility.

Pull request description:

  Wallet descriptors are useful for applications using the Bitcoin Core wallet as a backend for tracking coins, as they allow to track coins for multiple descriptors in a single wallet. However there is no information currently given for such applications to link a coin with an imported descriptor, severely limiting the possibilities for such applications of using multiple descriptors in a single wallet. This PR outputs the matching imported descriptor(s) for a given received coin in `listsinceblock` (and friends).

  It comes from a need for an application i'm working on, but i think it's something any software using `bitcoind` to track multiple descriptors in a single wallet would have eventually. For instance i'm thinking about the BDK project. Currently, the way to achieve this is to import raw addresses with labels and to have your application be responsible for wallet things like the gap limit.

  I'll add this to the output of `listunspent` too if this gets a few Concept ACKs.

Pull request description:

  # Concept

  Following https://github.com/bitcoin/bitcoin/pull/23789, Bitcoin Core wallet will now generate a change address that matches the payment address type. This improves privacy by not revealing which of the outputs is the change at the time of the transaction in scenarios where the input address types differ from the payment address type. However, information about the change can be leaked in a later transaction. This proposal attempts to address that concern.

  ## Leaking information in a later transaction

  Consider the following scenario:

  ![mix input types(1)](https://user-images.githubusercontent.com/7444140/158597086-788339b0-c698-4b60-bd45-9ede4cd3a483.png)

  1. Alice has a wallet with bech32 type UTXOs and pays Bob, who gives her a P2SH address
  2. Alice's wallet generates a P2SH change output, preserving her privacy in `txid: a`
  3. Alice then pays Carol, who gives her a bech32 address
  4. Alice's wallet combines the P2SH UTXO with a bech32 UTXO and `txid: b` has two bech32 outputs

  From a chain analysis perspective, it is reasonable to infer that the P2SH input in `txid: b` was the change from `txid: a`. To avoid leaking information in this scenario, Alice's wallet should avoid picking the P2SH output and instead fund the transaction with only bech32 Outputs. If the payment to Carol can be funded with just the P2SH output, it should be preferred over the bech32 outputs as this will convert the P2SH UTXO to bech32 UTXOs via the payment and change outputs of the new transaction.

  **TLDR;** Avoid mixing output types, spend non-default `OutputTypes` when it is economical to do so.

  # Approach

  `AvailableCoins` now populates a struct, which makes it easier to access coins by `OutputType`. Coin selection tries to find a funding solution by each output type and chooses the most economical by waste metric. If a solution can't be found without mixing, coin selection runs over the entire wallet, allowing mixing, which is the same as the current behavior.

  I've also added a functional test (`test/functional/wallet_avoid_mixing_output_types.py`) and unit test (`src/wallet/test/availablecoins_tests.cpp`.

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).
