Pull request description:
See #27463 for full project tracking.
This contains the first few commits of #30110, which require some thinking about thread safety in review.
- Introduce a new `m_tx_download_mutex` which guards the transaction download data structures including `m_txrequest`, the rolling bloom filters, and `m_orphanage`. Later this should become the mutex guarding `TxDownloadManager`.
- `m_txrequest` doesn't need to be guarded using `cs_main` anymore
- `m_recent_confirmed_transactions` doesn't need its own lock anymore
- `m_orphanage` doesn't need its own lock anymore
- Adds a new `ValidationInterface` event, `ActiveTipChanged`, which is a synchronous callback whenever the tip of the active chainstate changes.
- Flush `m_recent_rejects` and `m_recent_rejects_reconsiderable` on `ActiveTipChanged` just once instead of checking the tip every time `AlreadyHaveTx` is called. This should speed up calls to that function (no longer comparing a block hash each time) and removes the need to lock `cs_main` every time it is called.
Motivation:
- These data structures need synchronization. While we are holding `m_tx_download_mutex`, these should hold:
- a tx hash in `m_txrequest` is not also in `m_orphanage`
- a tx hash in `m_txrequest` is not also in `m_recent_rejects` or `m_recent_confirmed_transactions`
- In the future, orphan resolution tracking should also be synchronized. If a tx has an entry in the orphan resolution tracker, it is also in `m_orphanage`, and not in `m_txrequest`, etc.
- Currently, `cs_main` is used to e.g. sync accesses to `m_txrequest`. We should not broaden the scope of things it locks.
- Currently, we need to know the current chainstate every time we call `AlreadyHaveTx` so we can decide whether we should update it. Every call compares the current tip hash with `hashRecentRejectsChainTip`. It is more efficient to have a validation interface callback that updates the rejection filters whenever the chain tip changes.

55b6d7be68 validation: Don't load a snapshot if it's not in the best header chain. (Martin Zumsande)
Pull request description:
This was suggested by me in the discussion of #30288, which has more context.
If the snapshot is not an ancestor of the most-work header (`m_best_header`), syncing from that alternative chain leading to `m_best_header` should be prioritised. Therefore it's not useful loading the snapshot in this situation.
If the other chain turns out to be invalid or the chain with the snapshot retrieves additional headers so that it's the most-work one again (see functional test), `m_best_header` will change and loading the snapshot will be possible again.
Because of the work required to generate a conflicting headers chain, a situation with two conflicting chains should only be possible under extreme circumstances, such as major forks.

This is a synchronous callback notifying clients of all tip changes.
It allows clients to respond to a new block immediately after it is
connected. The synchronicity is important for things like
m_recent_rejects, in which a transaction's validity can change (rejected
vs accepted) when this event is processed. For example, the transaction
might have a timelock condition that has just been met. This is distinct
from something like m_recent_confirmed_transactions, in which the
validation outcome is the same (valid vs already-have), so it does not
need to be reset immediately.
If the snapshot is not an ancestor of the most-work header (m_best_header),
syncing from that alternative chain should be prioritised.
Therefore don't accept loading a snapshot in this situation.
If that other chain turns out to be invalid, m_best_header
would be reset and loading the snapshot should be possible again.
Because of the work required to generate a conflicting headers chain,
this should only be possible under extreme circumstances, such as major forks.

Pull request description:
The validation caches are currently setup independently from where the rest of the validation code is initialized. This makes their ownership semantics unclear. There is also no clear enforcement on when and in what order they need to be initialized. The caches are always initialized in the `BasicTestingSetup` although a number of tests don't actually need them.
Solve this by moving the caches from global scope into the `ChainstateManager` class. This simplifies the usage of the kernel library by no longer requiring manual setup of the caches prior to using the `ChainstateManager`. Tests that need to access the caches can instantiate them independently.

Pull request description:
This PR contains a number of vaguely-related improvements to the random module.
The specific changes and more detailed rationale is in the commit messages, but the highlights are:
* `XoRoShiRo128PlusPlus` (previously a test-only RNG) moves to random.h and becomes `InsecureRandomContext`, which is even faster than `FastRandomContext` but non-cryptographic. It also gets all helper randomness functions (`randrange`, `fillrand`, ...), making it a lot more succinct to use.
* During tests, **all** randomness is made deterministic (except for `GetStrongRandBytes`) but non-repeating (like `GetRand()` used to be when `g_mock_deterministic_tests` was used), either fixed, or from a random seed (overridden by env var).
* Several infrequently used top-level functions (`GetRandMillis`, `GetRandMicros`, `GetExponentialRand`) are converted into member functions of `FastRandomContext` (and `InsecureRandomContext`).
* `GetRand<T>()` (without argument) can now return the maximum value of the type (previously e.g. `GetRand<uint32_t>()` would never return 0xffffffff).

Adds a release note for TRUC policy which will be live in v28.0.
For clarity, replaces mentions of "v3" with "TRUC" in most places. Suggested in

- https://github.com/bitcoin/bitcoin/pull/29496#discussion_r1624500904
I changed error strings from "v3-violation" to "TRUC-violation" but left v3 in the debug strings because I think it might be clearer for somebody who is debugging. Similarly, I left some variables unchanged because I think they're more descriptive this way, e.g. `tx_v3_from_v2_and_v3`. I'm happy to debate places that should or shouldn't be documented differently in this PR, whatever is clearest to everyone.

19ce3d407e assumeutxo: Check snapshot base block is not marked invalid (Fabian Jahr)
80315c0118 refactor: Move early loadtxoutset checks into ActiveSnapshot (Fabian Jahr)
Pull request description:
This was discovered in a discussion in #29996
If the base block of the snapshot is marked invalid or part of an invalid chain, we currently still load the snapshot and get stuck in a weird state where we have the snapshot chainstate but it will never connect to our valid chain.
While this scenario is highly unlikely to occur on mainnet, it still seems good to prevent this inconsistent state.
The behavior change described above is in the second commit.
The first commit refactors the early checks in the `loadtxoutset` RPC by moving them into `ActivateSnapshot()` in order to have the chance to cover them by unit tests in the future and have a more consistent interface. Previously checks were spread out between `rpc/blockchain.cpp` and `validation.cpp`. In order to be able to return the error message to users of the RPC, the return type of `ActivateSnapshot()` is changed from `bool` to `util::Result`.
The third commit removes an unnecessary restart introduced in #29428.

Keep mentions of v3 in debug strings to help people who might not know
that TRUC is applied when version=3.
Also keep variable names in tests, as it is less verbose to keep v3 and v2.

Pull request description:
Allows any 2 transaction package with no in-mempool ancestors to do package RBF when directly conflicting with other mempool clusters of size two or less.
Proposed validation steps:
1) If the transaction package is of size 1, legacy rbf rules apply.
2) Otherwise the transaction package consists of a (parent, child) pair with no other in-mempool ancestors (or descendants, obviously), so it is also going to create a cluster of size 2. If larger, fail.
3) The package rbf may not evict more than 100 transactions from the mempool(bip125 rule 5)
4) The package is a single chunk
5) Every directly conflicted mempool transaction is connected to at most 1 other in-mempool transaction (ie the cluster size of the conflict is at most 2).
6) Diagram check: We ensure that the replacement is strictly superior, improving the mempool
7) The total fee of the package, minus the total fee of what is being evicted, is at least the minrelayfee * size of the package (equivalent to bip125 rule 3 and 4)
Post-cluster mempool this will likely be expanded to general package rbf, but this is what we can safely support today.

Pull request description:
This PR:
- moves warnings from common to the node library and into the node namespace (as suggested in https://github.com/bitcoin/bitcoin/pull/29845#discussion_r1570069541)
- generalizes the warnings interface to `Warnings::Set()` and `Warnings::Unset()` methods, instead of having a separate function and globals for each warning. As a result, this simplifies the `kernel::Notifications` interface.
- removes warnings.cpp from the kernel library
- removes warning globals
- adds testing for the warning logic
Behaviour change introduced:
- the `-alertnotify` command is executed for all `KernelNotifications::warningSet` calls, which now also covers the `LARGE_WORK_INVALID_CHAIN` warning
- the GUI is updated automatically whenever a warning is (un)set, covering some code paths where it previously wouldn't be, e.g. when `node::AbortNode()` is called, or for the `LARGE_WORK_INVALID_CHAIN` warning
Some discussion points:
- ~is `const std::string& id` the best way to refer to warnings? Enums are an obvious alternative, but since we need to define warnings across libraries, strings seem like a straightforward solution.~ _edit: updated approach to use `node::Warning` and `kernel::Warning` enums._

Support package RBF where the conflicting package would result
in a mempool cluster of size two, and each of its direct
conflicts are also part of an up-to-size-2 mempool cluster.
This restricted topology allows for exact calculation
of miner scores for each side of the equation, reducing
the surface area for new pins, or incentive-incompatible
replacements.
This allows wallets to create simple CPFP packages
that can fee bump other simple CPFP packages. This,
leveraged with other restrictions such as V3 transactions,
can create pin-resistant applications.
Future package RBF relaxations can be considered when appropriate.

Instead of having separate warning functions (and globals) for each
different warning that can be raised, encapsulate this logic into
a single class and allow to (un)set any number of warnings.
Introduces behaviour change:
- the `-alertnotify` command is executed for all
`KernelNotifications::warningSet` calls, which now also covers the
`LARGE_WORK_INVALID_CHAIN` warning.
- previously, warnings were returned based on a predetermined order,
e.g. with the "pre-release test build" warning always first. This
is no longer the case, and Warnings::GetMessages() will return
messages sorted by the id of the warning.
Removes warnings.cpp from kernel.
429ec1aaaa refactor: Rename CTransaction::nVersion to version (Ava Chow)
27e70f1f5b consensus: Store transaction nVersion as uint32_t (Ava Chow)
Pull request description:
Given that the use of a transaction's nVersion is always as an unsigned int, it doesn't make sense to store it as signed and then cast it to unsigned everywhere it is used and displayed.
Since a few alternative implementations have recently been revealed to have made an error with this signedness that would have resulted in consensus failure, I think it makes sense for us to just make this always unsigned to make it clear that the version is treated as unsigned. This would also help us avoid future potential issues with signedness of this value.
I believe that this is safe and does not actually change what transactions would or would not be considered both standard and consensus valid. Within consensus, the only use of the version in consensus is in BIP68 validation which was already casting it to uint32_t. Within policy, although it is used as a signed int for the transaction version number check, I do not think that this change would change standardness. Standard transactions are limited to the range [1, 2]. Negative numbers would have fallen under the < 1 condition, but by making it unsigned, they are still non-standard under the > 2 condition.
Unsigned and signed ints are serialized and unserialized the same way so there is no change in serialization.

32c80413fd bench: add benchmark for checkblockindex (Martin Zumsande)
Pull request description:
`CheckBlockIndex() ` are consistency checks that are currently enabled by default on regtest.
The function is rather slow, which is annoying if you
* attempt to run it on other networks, especially if not fully synced
* want to generate a long chain on regtest and see block generation slow down because you forgot to disable `-checkblockindex` or don't know it existed.
One reason why it's slow is that in order to be able to traverse the block tree depth-first from genesis, it inserts pointers to all block indices into a `std::multimap` - for which inserts and lookups become slow once there are hundred thousands of entries.
However, typically the block index is mostly chain-like with just a few forks so a multimap isn't really needed for the most part. This PR suggests to store the block indices of the chain ending in the best header in a vector instead, and store only the rest of the indices in a multimap. This does not change the actual consistency checks that are being performed for each index, just the way the block index tree is stored and traversed.
This adds a bit of complication to make sure each block is visited (note that there are asserts that check it), making sure that the two containers are traversed correctly, but it speeds up the function considerably:
On master, a single invocation of `CheckBlockIndex` takes ~1.4s on mainnet for me (4.9s on testnet which has >2.4 million blocks).
With this branch, the runtime goes down to ~0.27s (0.85s on testnet).This is a speedup by a factor ~5.

Pull request description:
When restarting `bitcoind` during an ongoing reindex without setting the `-reindex` flag again, the block and coins db is left intact, but any data from the optional indexes is discarded. While not a bug per se, wiping the data again is
wasteful, both in terms of having to write it again, as well as potentially leading to longer startup times. So keep the index data instead when continuing a prior reindex.
Also includes a bugfix and smaller code cleanups around the reindexing code. The bug was introduced in b47bd95920: "kernel: De-globalize fReindex".

In order to ensure that the change of nVersion to a uint32_t in the
previous commit has no effect, rename nVersion to version in this commit
so that reviewers can easily spot if a spot was missed or if there is a
check somewhere whose semantics have changed.
This is a just a mechanical change, renaming and inverting the meaning
of the indexing variable.
"m_blockfiles_indexed" is a more straightforward name for this variable
because this variable just indicates whether or not
<datadir>/blocks/blk?????.dat files have been indexed in the
<datadir>/blocks/index LevelDB database. The name "m_reindexing" was
more confusing, it could be true even if -reindex was not specified, and
false when it was specified. Also, the previous name unnecessarily
required thinking about the whole reindexing process just to understand
simple checks in validation code about whether blocks were indexed.
The motivation for this change is to follow up on previous commits,
moving away from having multiple variables called "reindex" internally,
and instead naming variables individually after what they do and
represent.

It does not control any actual logic and the log message as well as the
comment are obsolete, since no database initialization takes place there
anymore. Log messages indicating when indexes and chainstate databases
are loaded exist in other places.
