fa20f815a9 Remove txindex migration code (MarcoFalke)
fae8786033 doc: Fix validation typo (MarcoFalke)
fab89006d6 Add missing includes and forward declarations, remove unused ones (MarcoFalke)
Pull request description:
No supported version of Bitcoin Core used the legacy txindex, so all relevant nodes can be assumed to have upgraded. Thus, there is no need to keep this code any longer.
As a temporary courtesy, provide a one-time warning on how to free the disk space used by the legacy txindex.
Fixes#22615

Adjust CheckBlockIndex to account for
- assumed-valid block indexes lacking transaction data, and
- setBlockIndexCandidates for the background chainstate not containing certain entries
which rely on assumed-valid ancestors.
Mark the block index entries that are beneath the snapshot base block as
assumed-valid. Subsequent commits will make use of this flag in other
parts of the system.
Only perform certain behavior (namely that related to servicing
the getblocktemplate RPC call) for the active chainstate when
calling UpdateTip.

- Finish removing all references to 'recheckpeginblockinterval', including
documentation and tests.
- Remove periodic calls to MainchainRPCCheck; use it only at startup (and
refactor accordingly to simplify logic.)
- Move MainchainRPCCheck from validation.h/cpp (public) to an internal
helper function of init.cpp.
- Comment out definition of 'revalidation queue' type in txdb, to suppress
"unused variable" warning. (Leave it visible to avoid future reuse.)
Currently, if -validatepegin is given, and block validation can't proceed
because the parent chain is not synced, we mark the block invalid and put
it in a queue to be "revalidated" later. Unfortunately, marking a block
invalid has downstream consequences, in particular causing descendant blocks
to be marked invalid, which are not currently fixed by the queue.
Instead, we'll use a different strategy: if the mainchain daemon isn't
sufficiently synced to validate a block, we will "stall" connecting that
block to the chain, and have ActivateBestChain simply keep the tip at the
previous block until we're ready.
We can still download and validate (partly) blocks past this point while
we're waiting. They will be connected once the parent chain daemon catches
up.

Pull request description:
This PR does not change behavior. It extracts the BIP125 logic into helper functions (and puts them in the policy/rbf* files). This enables three things - I think each one individually is pretty good:
- Implementation of package RBF (see #22290). I want it to be as close to BIP125 as possible so that it doesn't become a distinct fee-bumping mechanism. Doing these move-only commits first means the diff is mostly mechanical to review, and I just need to create a function that mirrors the single transaction validation.
- We will be able to isolate and test our RBF logic alone. Recently, there have been some discussions on discrepancies between our code and BIP125, as well as proposals for improving it. Generally, I think making this code more modular and de-bloating validation.cpp is probably a good idea.
- Witness Replacement (replacing same-txid-different-wtxid when the witness is significantly smaller and therefore higher feerate) in a BIP125-similar way. Hopefully it can just be implemented with calls to the rbf functions (i.e. `PaysForRBF`) and an edit to the relevant mempool entries.

This forward-ports the new Taproot sighash but does not fix a couple
22-blocked TODOs related to the MissingDataBehavior enum. Should be fixed
in a followup commit.
One nontrivial change I had to make was feeding the genesis hash to SignTransaction
(the "global" one in script/sign.cpp) so that it could correctly compute
the sighash at signing time.

Pull request description:
See #22675 for motivation, this is one chunk of it. It extracts some BIP125 logic into policy/rbf:
- Defines a constant for specifying the maximum number of mempool entries we'd consider replacing by RBF
- Calls the available `SignalsOptInRBF` function instead of manually iterating through inputs
- Moves the logic for getting the list of conflicting mempool entries to a helper function
- Also does a bit of preparation for future moves - moving declarations around, etc
Also see #22677 for addressing the circular dependency.

The RecursiveMutex cs_nBlockSequenceId is only used at one place in
CChainState::ReceivedBlockTransactions() to atomically read-and-increment the
nBlockSequenceId member. At this point, the cs_main lock is set, hence we can
use a plain int for the member and mark it as guarded by cs_main.
No behavior change.
While we're looking through the descendants and calculating how many
transactions we might replace, quit early, as soon as we hit 100.
Since we're failing faster, we can also separate the loops - yes, we
loop through more times, but this helps us detangle the different BIP125
rules later.
A circular dependency is added because policy now depends on txmempool and
txmempool depends on validation. It is natural for [mempool] policy to
rely on mempool; the problem is caused by txmempool depending on
validation. #22677 will resolve this.
f685a13bef doc: GetTransaction()/getrawtransaction follow-ups to #22383 (John Newbery)
abc57e1f08 refactor: move `GetTransaction(...)` to node/transaction.cpp (Sebastian Falbesoner)
Pull request description:
~This PR is based on #22383, which should be reviewed first~ (merged by now).
In [yesterday's PR review club session to PR 22383](https://bitcoincore.reviews/22383), the idea of moving the function `GetTransaction(...)` from src/validation.cpp to src/node/transaction.cpp came up. With this, the circular dependency "index/txindex -> validation -> index/txindex" is removed (see change in `lint-circular-dependencies.sh`). Thanks to jnewbery for suggesting and to sipa for providing historical background.
Relevant IRC log:
```
17:52 <jnewbery> Was anyone surprised that GetTransaction() is in validation.cpp? It seems to me that node/transaction.cpp would be a more appropriate place for it.
17:53 <raj_> jnewbery, +1
17:53 <stickies-v> agreed!
17:54 <glozow> jnewbery ya
17:54 <jnewbery> seems weird that validation would call into txindex. I wonder if we remove this function, then validation would no longer need to #include txindex
17:54 <sipa> GetTransaction predates node/transaction.cpp, and even the generic index framework itself :)
17:55 <sipa> (before 0.8, validation itself used the txindex)
17:55 <jnewbery> (and GetTransaction() seems like a natural sibling to BroadcastTransaction(), which is already in node/transaction.cpp)
17:55 <jnewbery> sipa: right, this is not meant as a criticism of course. Just wondering if we can organize things a bit more rationally now that we have better separation between things.
17:55 <sipa> jnewbery: sure, just providing background
17:56 <sipa> seems very reasonable to move it elsewhere now
```
The commit should be trivial to review with `--color-moved`.

78f4c8b98e prefer to use txindex if available for GetTransaction (Jameson Lopp)
Pull request description:
Fixes#22382
Motivation: prevent excessive disk reads if txindex is enabled.
Worth noting that this could be argued to be less of a bug and more of an issue of undefined behavior. If a user calls GetTransaction with the wrong block hash, what should happen?

Pull request description:
Builds on #21009 and makes progress on remaining items in #17862
Removing `RewindBlockIndex()` in #21009 allows the following:
- removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
- move `test_upgrade_after_activation()` out of `p2p_segwit.py` reducing runtime
- in turn, that allows us to drop support for `-segwitheight=-1`, which is only supported for that test.
- that allows us to always set `NODE_WITNESS` in our local services. The only reason we don't do that is to support `-segwitheight=-1`.
- that in turn allows us to drop all of the `GetLocalServices() & NODE_WITNESS` checks inside `net_processing.cpp`, since our local services would always include `NODE_WITNESS`
