Pull request description:
This PR adds a `createwalletdescriptor` RPC which allows users to add new automatically generated descriptors to their wallet, e.g. to upgrade a 0.21.x wallet to contain a taproot descriptor. This RPC takes 3 arguments: the output type to create a descriptor for, whether the descriptor will be internal or external, and the HD key to use if the user wishes to use a specific key. The HD key is an optional parameter. If it is not specified, the wallet will use the key shared by the active descriptors, if they are all single key. For most users in the expected upgrade scenario, this should be sufficient. In more advanced cases, the user must specify the HD key to use.
Currently, specified HD keys must already exist in the wallet. To make it easier for the user to know, `gethdkeys` is also added to list out the HD keys in use by all of the descriptors in the wallet. This will include all HD keys, whether we have the private key, for it, which descriptors use it and their activeness, and optionally the extended private key. In this way, users with more complex wallets will be still be able to get HD keys from their wallet for use in other scenarios, and if they want to use `createwalletdescriptor`, they can easily get the keys that they can specify to it.

4d5b55735b log: renamed disk to file so wording was more accurate (kevkevin)
b9f04be870 mempool: Log added for dumping mempool transactions to disk (kevkevin)
Pull request description:
Sometimes when shutting off bitcoind it can take a while to dump the mempool transaction onto the disk so
this change adds additional logging to the `DumpMempool` method in `kernel/mempool_persist.cpp`
Motivated by https://github.com/bitcoin/bitcoin/pull/29227 this change
- adds a single new line for the amount of transactions being dumped and the amount of memory being dumped to file
This is in response to https://github.com/bitcoin/bitcoin/pull/29227#issuecomment-1893375082

Pull request description:
The `mempool_conflicts` variable is added to `CWalletTx`, it is a set of txids of txs in the mempool conflicting with the wallet tx or a wallet tx's parent. This PR only changes how mempool-conflicted txs are dealt with in memory.
`IsSpent` now returns false for an output being spent by a mempool conflicted transaction where it previously returned true.
A txid is added to `mempool_conflicts` during `transactionAddedToMempool`. A txid is removed from `mempool_conflicts` during `transactionRemovedFromMempool`.
This PR also adds a `mempoolconflicts` field to the `gettransaction` wallet RPC result.

Pull request description:
This is a smaller piece of https://github.com/bitcoin/bitcoin/pull/28984 broken off for easier review.
Up to date explanation of diagram checks are here: https://delvingbitcoin.org/t/mempool-incentive-compatibility/553
This infrastructure has two near term applications prior to cluster mempool:
1) Limited Package RBF(https://github.com/bitcoin/bitcoin/pull/28984): We want to allow package RBF only when we know it improves the mempool. This narrowly scoped functionality allows use with v3-like topologies, and will be expanded at some point post-cluster mempool when diagram checks can be done efficiently against bounded cluster sizes.
2) Replacement for single tx RBF(in a cluster size of up to two) against conflicts of up to cluster size two. `ImprovesFeerateDiagram` interface will have to change for this use-case, which is a future direction to solve certain pins and improve mempool incentive compatibility: https://delvingbitcoin.org/t/ephemeral-anchors-and-mev/383#diagram-checks-fix-this-3
And longer-term, this would be the proposed way we would compute incentive compatibility for all conflicts, post-cluster mempool.

824f47294a node: Use log levels in noui_ThreadSafeMessageBox (TheCharlatan)
ddc7872c08 node: Make translations of fatal errors consistent (TheCharlatan)
Pull request description:
The extra `bilingual_str` argument of the fatal error notifications and `node::AbortNode()` is often unused and when used usually contains the same string as the message argument. It also seems to be confusing, since it is not consistently used for errors requiring user action. For example some assumeutxo fatal errors require the user to do something, but are not translated.
So simplify the fatal error and abort node interfaces by only passing a translated string. This slightly changes the fatal errors displayed to the user.

6205466512 rpc: "addpeeraddress tried" return error on failure (0xb10c)
Pull request description:
When trying to add an address to the IP address manager tried table, it's first added to the new table and then moved to the tried table. Previously, adding a conflicting address to the address manager's tried table with test-only `addpeeraddress tried=true` RPC would return `{ "success": true }`. However, the address would not be added to the tried table, but would remain in the new table. This caused, e.g., issue #28964.
This is fixed by new returning `{ "success": false, "error": "..." }` for failed tried table additions. Since the address remaining in the new table can't be removed (the address manager interface does not support removing addresses at the moment and adding this seems to be a bigger effort), an error message is returned. This indicates to a user why the RPC failed and allows accounting for the extra address in the new table. This is done in the functional test for the `getrawaddrman` RPC.

Pull request description:
The `PopulateAndValidateSnapshot` function introduced in f6e2da5fb7 from #19806 has been setting fake `nTx` and `nChainTx` values that can show up in RPC results (https://github.com/bitcoin/bitcoin/issues/29328) and make `CBlockIndex` state hard to reason about, because it is difficult to know whether the values are real or fake.
Revert to previous behavior of setting `nTx` and `nChainTx` to 0 when the values are unknown, instead of faking them. Also drop no-longer needed `BLOCK_ASSUMED_VALID` flag.
Dropping the faked values also fixes assert failures in the `CheckBlockIndex` `(pindex->nChainTx == pindex->nTx + prev_chain_tx)` check that could happen previously if forked or out-of-order blocks before the snapshot got submitted while the snapshot was being validated. The PR includes two commits adding tests for these failures and describing them in detail.
Compatibility note: This change could cause new `-checkblockindex` failures if a snapshot was loaded by a previous version of Bitcoin Core and not fully validated, because fake `nTx` values will have been saved to the block index. It would be pretty easy to avoid these failures by adding some compatibility code to `LoadBlockIndex` and changing `nTx` values from 1 to 0 when they are fake (when `(pindex->nStatus & BLOCK_VALID_MASK) < BLOCK_VALID_TRANSACTIONS`), but a little simpler not to worry about being compatible in this case.

dfcef536d0 blockstorage: do not flush block to disk if it is already there (Matthew Zipkin)
Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/2039
When reindexing from flat-file block storage there is no need to write anything back to disk, since the block data is already there. This PR skips flushing to disk those blocks that already have a known position in the datastore. Skipping this means that users can write-protect the `blk` files on disk which may be useful for security or even safely sharing that data between multiple bitcoind instances.
`FindBlockPos()` may also flush the undo data file, but again this is skipped if the corresponding block position is known, like during the initial stage of a reindex when block data is being indexed. Once the block index is complete the validation mechanism will call `ConnectBlock()` which will save undo data at that time.
The call stack looks like this:
```
init()
ThreadImport() <-- process fReindex flag
LoadExternalBlockFile()
AcceptBlock()
SaveBlockToDisk()
FindBlockPos()
FlushBlockFile() <-- unnecessary if block is already on disk
```
A larger refactor of this part of the code was started by mzumsande here: https://github.com/mzumsande/bitcoin/tree/202207_refactor_findblockpos including this fix, reviewers can let me know if the changes should be combined.

bcbd7eb8d4 bench: basic block filter index initial sync (furszy)
Pull request description:
Work decoupled from #26966 per request.
The aim is to remove an unnecessary disk read operation that currently takes place with every new arriving block (or scanned block during background sync). Instead of reading the last filter header from disk merely to access its hash for constructing the next filter, this work caches it, occupying just 32 more bytes in memory.
Also, reduces `cs_main` lock contention during the index initial sync process. And, simplifies the indexes initialization and shutdown procedure.
Testing Note:
To compare the changes, added a pretty basic benchmark in the second commit. Alternatively, could also test the changes by timing the block filter sync from scratch on any network; start the node with `-blockfilterindex` and monitor the logs until the syncing process finish.
