This should also fix an init error if a -walletdir with a trailing slash
is used on windows. This appears to be a real error and regression
introduced with #20744.
On windows (or at least wine), fs calls that actuallly access the
filesystem like fs::equivalent or fs::exists seem to treat directory
paths with trailing slashes as not existing, so it's necessary to
normalize these paths before using them. This change passes canonical
paths to fs calls validating the -walletdir path to fix this.
Warning: Replacing fs::system_complete calls with fs::absolute calls
in this commit may cause minor changes in behaviour because fs::absolute
no longer strips trailing slashes; however these changes are believed to
be safe.

Name has been confusing since it was introduced, and it was pointed in
recent review club as https://bitcoincore.reviews/10102 that it was
particularly unclear how interfaces::WalletClient was different from
interfaces::Wallet.

Pull request description:
Instead of returning a set of selected coins and their total value as separate items, encapsulate both of these, and other variables, into a new `SelectionResult` struct. This allows us to have all of the things relevant to a coin selection solution be in a single object. `SelectionResult` enables us to implement the waste calculation in a cleaner way.
All of the coin selection functions (`SelectCoinsBnB`, `KnapsackSolver`, `AttemptSelection`, and `SelectCoins`) are changed to use a `SelectionResult` as the output parameter.

This removes the ability to set an offset in the SpanReader constructor,
as the current code is broken. All call sites use pos=0, so it is actually
unused. If future call sites need it, SpanReader{a, b, c, d} is equivalent
to SpanReader{a, b, c.subspan(d)}.
It also removes the ability to deserialize from SpanReader directly from
the constructor. This too is unused, and can be more idiomatically
simulated using (SpanReader{a, b, c} >> x >> y >> z) instead of
SpanReader{a, b, c, x, y, z}.
Replace the CoinSet actual_selection with a SelectionResult
expected_result. We don't use the SelectionResult functions yet, but
will soon.

456e350926 wallet: resolve ambiguity of two ScriptPubKey managers providing same script (S3RK)
Pull request description:
This PR fixes certain use-cases when **send-to-self** transactions are missing from `listtransactions` output.
1. When a receiving address is generated externally to the wallet
(e.g. same wallet running on two nodes, or by 3rd party from xpub)
2. When restoring backup with lost metadata, but keypool gap is not exceeded yet
When the block is connected or tx added to mempool we already mark used keys. This PR extends this logic to determine whether the destination is a receiving one and if yes add it to the address book with empty label.
Works both for legacy and descriptors wallets.
- For legacy it uses the internal flag from the keypool entry. Caveat: because we don't know which script type would be used we add all possible destinations for such keys.
- For descriptor wallets it uses internal flag for the script pub key manager. Caveat: it only works for active descriptors.

f13a22a631 wallet: Call load handlers without cs_wallet locked (João Barbosa)
Pull request description:
Don't have `cs_wallet` locked while calling each `context.wallet_load_fns`. A load handler can always lock `cs_wallet` if needed.
The lock was added in 1c7e25db0c to satisfy TSAN. With 44c430ffac most of the code requiring the lock is in `CWallet::AttachChain`. A comment is added to warn about wallets_mutex and cs_wallet lock ordering.

d8ee8f3cd3 refactor: Make CWalletTx sync state type-safe (Russell Yanofsky)
Pull request description:
Current `CWalletTx` state representation makes it possible to set inconsistent states that won't be handled correctly by wallet sync code or serialized & deserialized back into the same form.
For example, it is possible to call `setConflicted` without setting a conflicting block hash, or `setConfirmed` with no transaction index. And it's possible update individual `m_confirm` and `fInMempool` data fields without setting an overall consistent state that can be serialized and handled correctly.
Fix this without changing behavior by using `std::variant`, instead of an enum and collection of fields, to represent sync state, so state tracking code is safer and more legible.
This is a first step to fixing state tracking bugs https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking, by adding an extra margin of safety that can prevent new bugs from being introduced as existing bugs are fixed.

54011e7aa2 refactor: use CWallet const shared pointers when possible (Karl-Johan Alm)
96461989a2 refactor: const shared_ptrs (Karl-Johan Alm)
Pull request description:
```C++
const std::shared_ptr<CWallet> wallet = x;
```
means we can not do `wallet = y`, but we can totally do `wallet->DestructiveOperation()`, contrary to what that line looks like.
This PR
* introduces a new convention: always use const shared pointers to `CWallet`s (even when we mutate the pointed-to thing)
* uses `const shared_ptr<const CWallet>` everywhere where wallets are not modified
In the future, this should preferably apply to all shared pointers, not limited to just `CWallet`s.
Both of these serve the same purpose: to dispell the misconception that `const shared_ptr<X>` immutates `X`. It doesn't, and it's dangerous to leave this misconception as is, for obvious reasons.

Introduce convention to use const shared pointers everywhere, unless the shared pointer is modified at some point, which it very rarely is.
We want this convention, as it helps alleviate the misconception that a const shared pointer somehow results in a pointer to an immutable object, which is false.
Instead of using AddToWallet so that making a COutput will work,
directly add the transaction into wallet.mapWallet. This bypasses many
checks that AddToWallet will do which are pointless and just slow down
this test.
For the generic wallet tests, make DescriptorScriptPubKeyMans. There are
still some wallet tests that test legacy wallet things. Those remain
unchanged.
The subtract fee from outputs assumes that the leftover input amount
will be dropped to fees. However this only happens if that amount is
less than the cost of change. In the event that it is higher than the
cost of change, the leftover amount will actually become a change
output. To avoid this scenario, force a change type which has a high
cost of change.
To avoid issues with test data leaking across tests cases, the global
vCoins and testWallet are removed from coinselector_tests and all of the
relevant functions reworked to not need them.
There is no change in behavior. This just helps prepare for the
transition from boost::filesystem to std::filesystem by avoiding calls
to methods which will be unsafe after the transaction to std::filesystem
to due lack of a boost::filesystem::path::imbue equivalent and inability
to set a predictable locale.

There are two more cases where waste can be 0, when:
- (Fee - LTF) == -Change Cost
- (Fee - LTF) == -Excess
Adding these two conditions explicitly in the unit test will help
pin the behavior, also demonstrate waste calculation scenarios to new
readers.
