Instead of having a pointer to the CWalletTx in COutput, we can just
store the COutPoint and the CTxOut as those are the only things we need
from the CWalletTx. Other things CWalletTx used to provide were time and
fIsFromMe but these are also being stored by COutput.
Instead of determining whether the containing transaction is from the
wallet dynamically as needed, just pass it in to COutput and store it.
The transaction ownership isn't going to change.
fa8e76bb90 wallet: Add sanity checks to AntiFeeSnipe (MarcoFalke)
Pull request description:
I added those sanity checks as part of implementing BIP 326, but I think they make sense on their own. The checks require the transaction to be passed in to `DiscourageFeeSniping`. Also, replace `(int)locktime` cast with the equivalent `int(locktime)` cast.

ec7d73628a [wallet] assert BnB internally calculated waste is the same as GetSelectionWaste() (glozow)
Pull request description:
#22009 introduced a `GetSelectionWaste()` function to determine how much "waste" a coin selection solution has, and is a mirror of the waste calculated inside of `SelectCoinsBnB()`. It would be bad for these two waste metrics to deviate, since it could negatively affect how often we select the BnB solution. Add an assertion to help tests catch a potential accidental change.

These two implementations of waste calculation should never deviate.
Still keep the SelectCoinsBnB internal calculation because incremental
calculate-as-you-go is much more performant than calling
GetSelectionWaste() over and over again.
8ea6167099 wallet: refactor: dedup sqlite blob binding (Sebastian Falbesoner)
Pull request description:
This refactoring PR deduplicates repeated SQLite blob binding to a statement with a newly introduced helper function `BindBlobToStatement`, abstracting away the calls to `sqlite3_bind_blob(...)`.
This should be more readable and less error-prone, e.g. in case that the error handling has to be adapted. As a slight drawback, the function where the binding happens is not printed anymore (`__func__`), i.e. one could argue this is not strictly a refactoring, but IMHO the advantages of deduplication outweigh this; binding errors are purely internal logic errors (wrong use of the sqlite API) rather than something that is dependend on external data like DB content.

961b9e4e40 wallet: Parse hdKeypath if key_origin is not available (Andrew Chow)
0652ee73ec Add size check on meta.key_origin.path (Rob Fielding)
Pull request description:
Currently inactive HD chains are only derived from at the time a key in that chain is found to have been used. However, at that time, the wallet may not be able to derive keys (e.g. it is locked). Currently we would just move on and not derive any new keys, however this could result in missing funds.
This PR resolves this problem by adding memory only variables to `CHDChain` which track the highest known index. `TopUp` is modified to always try to top up the inactive HD chains, and this process will use the new variables to determine how much to top up. In this way, after an encrypted wallet is unlocked, the inactive HD chains will be topped up and hopefully funds will not be missed.
Note that because these variables are not persisted to disk (because `CHDChain`s for inactive HD chains are not written to disk), if an encrypted wallet is not unlocked in the same session as a key from an inactive chain is found to be used, then it will not be topped up later unless more keys are found.
Additionally, wallets which do not have upgraded key metadata will not derive any keys from inactive HD chains. This is resolved by using the derivation path string in `CKeyMetadata.hdKeypath` to determine what indexes to derive.

Instead of having CBlockIndex's live on the heap, which requires manual
memory management, have them be owned by m_block_index. This means that
they will live and die with BlockManager.
A change to BlockManager::LookupBlockIndex:
- Previously, it was a const member function returning a non-const CBlockIndex*
- Now, there's are const and non-const versions of
BlockManager::LookupBlockIndex returning a CBlockIndex with the same
const-ness as the member function:
(e.g. const CBlockIndex* LookupBlockIndex(...) const)
See next commit for some weirdness that this eliminates.
The range based for-loops are modernize (using auto + destructuring) in
a future commit.

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.

fa65bbf217 span: Add BytePtr helper (MarcoFalke)
Pull request description:
This changes the serialize code (`.read()` and `.write()` functions) to take a `Span` instead of a pointer and size. This is a breaking change for the serialize interface, so at no additional cost we can also switch to `std::byte` (instead of using `char`).
The benefits of using `Span`:
* Less verbose and less fragile code when passing an already existing `Span`(-like) object to or from serialization
The benefits of using `std::byte`:
* `std::byte` can't accidentally be mistaken for an integer
The goal here is to only change serialize to use spans of `std::byte`. If needed, `AsBytes`, `MakeUCharSpan`, ... can be used (temporarily) to pass spans of the right type.

Pull request description:
Issues:
- `CBlockIndex` member functions `GetBlockPos()`, `GetUndoPos()`, `IsAssumedValid()`, `RaiseValidity()`, and `IsValid()` and block storage functions `WriteUndoDataForBlock()` and `IsBlockPruned()` are missing thread safety lock annotations to help ensure that they are called with mutex cs_main to avoid bugs like #22895. Doing this also enables the next step:
- `CBlockIndex::nStatus` may be racy, i.e. potentially accessed by multiple threads, see #17161. A solution is to guard it by cs_main, along with fellow data members `nFile`, `nDataPos` and `nUndoPos`.
This pull:
- adds thread safety lock annotations for the functions listed above
- guards `CBlockIndex::nStatus`, `nFile`, `nDataPos` and `nUndoPos` by cs_main
How to review and test:
- debug build with clang and verify there are no `-Wthread-safety-analysis` warnings
- review the code to verify each annotation or lock is necessary and sensible, or if any are missing
- look for whether taking a lock can be replaced by a lock annotation instead

dddd05e7a3 qt: Treat unconfirmed txs as unconfirmed (MarcoFalke)
Pull request description:
The wallet has several issues:
## Unconfirmed txs in the GUI
The GUI clumsily attempts to guess if unconfirmed txs are locked until a future time. This is currently based on the locktime only, not nSequence, thus wrong. Fix this by removing the clumsy code and treat all unconfirmed txs as unconfirmed. The GUI already prints whether a tx is in the mempool, in which case the user knows that the tx wasn't locked until a future time. If the tx is not in the mempool, it might be better to report the exact reject reason from the mempool instead of using incorrect heuristics.
## Confirmed txs in the wallet
The wallet drops coins that it incorrectly assumes to be locked until a future time, even if they are already confirmed in the chain. This is because the wallet is using the wrong time (adjusted network time) instead of MTP, due to the `-1` default argument of `CheckFinalTx`.
The issues are fixed in separate commits and there is even a test.

Coin selection requires knowing the weight of a transaction so that fees
can be estimated. However for external inputs, the weight may not be
avialble, and solving data may not be enough as the input could be one
that we do not support. By allowing users to specify input weights,
those external inputs can be included in the transaction.
Additionally, if the weight for an input is specified, that value will
always be used, regardless of whether the input is in the wallet or
solving data is available. This allows us to account for scenarios where
the wallet may be more conservative and estimate a larger input than may
actually be created.
For example, we assume the maximum DER signature size, but an external
input may be signed by a wallet which does nonce grinding in order to get
a smaller signature. In that case, the user can specify the smaller
input weight to avoid overpaying transaction fees.
