c371cae07a test, init: perturb file to ensure failure instead of only deleting them (brunoerg)
Pull request description:
In `feature_init.py` there is a TODO about perturbing the files instead of only testing by deleting them.
```py
# TODO: at some point, we should test perturbing the files instead of removing
# them, e.g.
#
# contents = target_file.read_bytes()
# tweaked_contents = bytearray(contents)
# tweaked_contents[50:250] = b'1' * 200
# target_file.write_bytes(bytes(tweaked_contents))
#
# At the moment I can't get this to work (bitcoind loads successfully?) so
# investigate doing this later.
```
This PR adds it by writing into the file random bytes and checking whether it throws an error when starting.

afc2dd5484 test: various `converttopsbt` check cleanups in rpc_psbt.py (Sebastian Falbesoner)
Pull request description:
In the functional test rpc_psbt.py, some comments around the `converttopsbt` RPC checks are wrong or outdated and can be removed:
> _Error could be either "TX decode failed" (segwit inputs causes
> parsing to fail) or "Inputs must not have scriptSigs and
> scriptWitnesses"_
Decoding a valid TX with at least one input always succeeds with the [heuristic](e352f5ab6b/src/core_read.cpp (L126)), i.e. this comment is not right and we can assert for the error string "Inputs must not have scriptSigs and scriptWitnesses" on the calls below.
> _We must set iswitness=True because the serialized transaction has
> inputs and is therefore a witness transaction_
This is also unneeded (and confusing, w.r.t. "is therefore a witness transaction"?), for a TX with one input there is no need to set the `iswitness` parameter. For sake of completeness, we still keep one variant where iswitness is explicitly set to true.
Lastly, there is a superflous `converttopsbt` call on the raw tx which is the same as just [about ~10 lines above](https://github.com/bitcoin/bitcoin/blob/master/test/functional/rpc_psbt.py#L393-L397), so it can be removed.

c4981e7f63 prune, import: fixes#23852 (mruddy)
Pull request description:
Fixes#23852
This allows pruning to work during the `-loadblock` import process.
An example use case is where you have a clean set of block files and you want to create a pruned node from them, but you don't want to alter the input set of block files.
#23852 noted that pruning was not working reliably during the loadblock import process. The reason why the loadblock process was not pruning regularly as it progressed is that the pruning process (`BlockManager::FindFilesToPrune`) checks the tip height of the active chainstate, and `CChainState::ActivateBestChain` was not called (which updates that tip height) in `ThreadImport` until after all the import files were processed.
An example bash command line that makes it easy to import a bunch of block files:
```
./src/qt/bitcoin-qt -debug -logthreadnames -datadir=/tmp/btc -prune=550 -loadblock=/readonly/btc/main/blk{00000..00043}.dat
```
One interesting side note is that `CChainState::ActivateBestChain` can be called while the import process is running (in the `loadblk` thread) by concurrent network message processing activity in the `msghand` thread. For example, one way to reproduce this easily is with the `getblockfrompeer` RPC (requesting a block with height greater than 100000) run from a node connected to an importing node. There are other ways too, but this is an easy way. I only mention this to explain how the `max_prune_height=225719` log message in the original issue came to occur.

8f14fc8622 test: cover fastprune with excessive block size (Matthew Zipkin)
271c23e87f blockstorage: Adjust fastprune limit if block exceeds blockfile size (Martin Zumsande)
Pull request description:
The debug-only `-fastprune` option used in several tests is not always safe to use:
If a `-fastprune` node receives a block larger than the maximum blockfile size of `64kb` bad things happen: The while loop in `BlockManager::FindBlockPos` never terminates, and the node runs oom because memory for `m_blockfile_info` is allocated in each iteration of the loop.
The same would happen if a naive user used `-fastprune` on anything other than regtest (so this can be tested by syncing on signet for example, the first block that crashes the node is at height 2232).
Change the approach by raising the blockfile size to the size of the block, if that block otherwise wouldn't fit (idea by TheCharlatan).

7bffec6715 bumpfee: enable send coins back to yourself (furszy)
Pull request description:
Simple example:
1) User_1 sends 0.1 btc to user_2 on a low fee transaction.
2) After few hours, the tx is still in the mempool, user_2
is not interested anymore, so user_1 decides to cancel
it by sending coins back to himself.
3) User_1 has the bright idea of opening the explorer and
copy the change output address of the transaction. Then
call bumpfee providing such output (in the "outputs" arg).
Currently, this is not possible. The wallet fails with
"Unable to create transaction. Transaction must have at least
one recipient" error.
The error reason is because we discard the provided output
from the recipients list and set it inside the coin control
so the process adds it later (when the change is calculated).
But.. there is no later if the tx has no outputs.

a5986e82dd refactor: Remove CAddressBookData::destdata (Ryan Ofsky)
5938ad0bdb wallet: Add DatabaseBatch::ErasePrefix method (Ryan Ofsky)
Pull request description:
This is cleanup that doesn't change external behavior. Benefits of the cleanup are:
- Removes awkward `StringMap` intermediate representation for wallet address metadata.
- Simplifies `CWallet`, deals with used address and received request serialization in `walletdb.cpp` instead of higher level wallet code
- Adds test coverage and documentation
This PR doesn't change externally observable behavior. Internally, the only change in behavior is that `EraseDestData` deletes rows directly from the database because they are no longer stored in memory. This is more direct and efficient because it uses a single lookup and scan instead of multiple lookups.
Motivation for this cleanup is making changes like #18550, #18192, #13756 easier to reason about and less likely to result in unintended behavior and bugs

Pull request description:
Part of package relay, see #27463.
Note that this still allows packages to bump transactions that are below the dynamic mempool minimum feerate, which means this still solves the "mempool is congested and my presigned 1sat/vB tx is screwed" problem for all transactions.
On master, the package policy (only accessible through regtest-only RPC submitpackage) allows 0-fee (or otherwise below min relay feerate) transactions if they are bumped by a child. However, with default package limits, we don't yet have a DoS-resistant way of ensuring these transactions remain bumped throughout their time in the mempool. Primarily, the fee-bumping child may later be replaced by another transaction that doesn't bump the parent(s). The parent(s) could potentially stay bumped by other transactions, but not enough to ever be selected by the `BlockAssembler` (due to `blockmintxfee`).
For example, (tested [here](https://github.com/glozow/bitcoin/commits/26933-motivation)):
- The mempool accepts 24 below-minrelayfeerate transactions ("0-fee parents"), all bumped by a single high-fee transaction ("the fee-bumping child"). The fee-bumping child also spends a confirmed UTXO.
- Two additional children are added to each 0-fee parent. These children each pay a feerate slightly above the minimum relay feerate (e.g. 1.9sat/vB) such that, for each 0-fee parent, the total fees of its two children divided by the total size of the children and parent is above the minimum relay feerate.
- If a block template is built now, all transactions would be selected.
- A transaction replaces the the fee-bumping child, spending only the confirmed UTXO and not any of the outputs from the 0-fee parents.
- The 0-fee parents now each have 2 children. Their descendant feerates are above minrelayfeerate, which means that they remain in the mempool, even if the mempool evicts all below-minrelayfeerate packages.
- If a block template is built now, none of the 0-fee parents or their children would be selected.
- Even more low-feerate descendants can be added to these below-minrelayfeerate packages and they will not be evicted until they expire or the mempool reaches capacity.
Unless we have a DoS-resistant way of ensuring package CPFP-bumped transactions are always bumped, allowing package CPFP to bump below-minrelayfeerate transactions can result in these problematic situations. See #27018 which proposes a partial solution with some limitations, and contains discussion about potential improvements to eviction strategy. While no adequate solution exists, for now, avoid these situations by requiring all transactions to meet min relay feerate.

96bf0bca4a test: simplify uint256 (de)serialization routines (Sebastian Falbesoner)
Pull request description:
These routines look fancy, but do nothing more than converting between byte objects of length 32 to/from integers in little endian byte order and can be replaced by simple one-liners, using the `int.{from,to}_bytes` methods (available since Python 3.2).
