Sending multiple large messages is rather slow with the non-optimized python
implementation of ChaCha20.
Apart from the slowness, these tests would also run successfully with v2.
By adding to the test framework a wait until the v2 handshake
is completed, so that p2p_sendtxrcncl.py (which doesn't need
to be changed itself) doesnt't send out any other messages before that.

There are occasions where a multi-statement tx is begun in one batch,
and a second batch is created which does a normal write (without a
multi-statement tx). These should not conflict with each other and all
of the data should end up being written to disk.
A SQLiteBatch need to wait for any other batch to finish writing before
it can begin writing, otherwise db txn state may be incorrectly
modified. To enforce this, each SQLiteDatabase has a semaphore which
acts as a lock and is acquired by a batch when it begins a write, erase,
or a transaction, and is released by it when it is done.
To avoid deadlocking on itself for writing during a transaction,
SQLiteBatch also keeps track of whether it has begun a transaction.

b198b9c2ce test: p2p: introduce helper for sending prepared VERSION message (Sebastian Falbesoner)
Pull request description:
This PR addresses a quirk in the test framework's p2p implementation regarding the version handshake protocol:
Currently, the VERSION message is sent immediately after an inbound connection (i.e. TestNode outbound connection) is made. This doesn't follow the usual protocol flow where the initiator sends a version first, the responder processes that and only then responds with its own version message. Change that accordingly by only sending immediate VERSION message for outbound connections (or after v2 handshake for v2 connections, respectively), and sending out VERSION message as response for incoming VERSION messages (i.e. in the function `on_version`) for inbound connections.
I first stumbled upon this issue through reading comment https://mirror.b10c.me/bitcoin-bitcoin/24748/#discussion_r1465420112 (see last paragraph) and recently again in the course of working on a v2-followup for #29279, where this causes issues for TestNode outbound connections that disconnect *before* sending out their own version message.
Note that these changes lead to slightly more code in some functional tests that override the `on_version` method, as the version reply has to be sent explicitly now, but I think is less confusing and reflects better what is actually happening.

Executing the unit tests for the bip324_cipher.py module currently
takes quite long (>60 seconds on my notebook). Most time here is spent
in empty plaintext/ciphertext encryption/decryption loops:
....
for _ in range(msg_idx):
enc_aead.encrypt(b"", b"")
...
for _ in range(msg_idx):
enc_aead.decrypt(b"", bytes(16))
...
Their sole purpose is increasing the FSChaCha20Poly1305 packet
counters in order to trigger rekeying, i.e. the actual
encryption/decryption is not relevant, as the result is thrown away.
This commit speeds up the tests by supporting to pass "None" as
plaintext/ciphertext, indicating to the routines that no actual
encryption/decryption should be done.

Note that another reason for disconnect after receiving a MEMPOOL msg of a peer
is if bloom filters are disabled on the node. This case is covered in the
functional test `p2p_nobloomfilter_messages.py`.
This ensures that the disconnect happens for the expected reason and
also makes it easier to navigate between implementation and test code,
i.e. both the questions "do we have test coverage for this disconnect?"
(from an implementation reader's perspective) and "where is the code
handling this disconnect?" (from a test reader's perspective) can be
answered simply by grep-ping the corresponding debug message.

9332c7edda wallet: Write bestblock to watchonly and solvable wallets (Ava Chow)
Pull request description:
A transaction does not necessarily have to belong to either the migrated wallet (with the private keys) and the watchonly wallet (with watchonly things), it could have multiple outputs with each isminetype. So we should be putting such transactions in one or the other wallet, but rather putting it in both.
I've added a test for this behavior, however the test also revealed a few other issues. Notably, it revealed that `migratewallet` would have the watchonly wallet rescan from genesis when it is reloaded at the end of migration. This could be a cause for migration appearing to be very slow. This is resolved by first writing best block records to the watchonly and solvable wallets, as well as updating the test to make sure that rescans don't happen.
The change to avoid rescans also found an issue where some of our early exits would result in unloading the wallet even though nothing happened. So there is also a commit to reload the wallet for such early exits.

When initiating a v2 connection and being immediately disconnected,
a node cannot know if the disconnect happens because the peer only
supports v1, or because it has banned you, so it schedules to reconnect with v1.
If the test doesn't wait for that, the reconnect can happen at a bad time,
resulting in failure in a later connect_nodes call.
Also add the test with --v2transport to the test runner.
It is possible for a transaction that has an output that belongs to the
mgirated wallet, and another output that belongs to the watchonly
wallet. Such transaction should appear in both wallets during migration.
We want to make sure that all of the transactions are being copied to
the watchonly and solvable wallets as expected. The automatic rescanning
behavior can cause us to pass a test by finding the transaction
on loading rather than having it be copied as expected.
Migration will unload loaded wallets prior to beginning. It will then
perform some checks which may exit early. Such unloaded wallets should
be reloaded prior to exiting.
When migrating, we should also be writing the bestblock record to the
watchonly and solvable wallets to avoid rescanning on the reload as that
can be slow.
25dc87e6f8 libconsensus: deprecate (Cory Fields)
Pull request description:
This library has existed for nearly 10 years with very little known uptake or impact. It has become a maintenance burden. In several cases it dictates our code/library structure (for example necessitating LIBBITCOIN_CRYPTO_BASE), as well as build-system procedures (building multiple copies of object files especially for the lib).
Several discussions have arisen wrt migrating it to CMake and it has become difficult to justify adding more complexity for a library that is virtually unused anyway.
See for example the discussions:
https://github.com/hebasto/bitcoin/pull/41https://github.com/bitcoin/bitcoin/pull/29123
And here: https://github.com/bitcoin/bitcoin/pull/29180
Where it is pointed out that the libbitcoinconsensus functions are slower than those the internal bitcoind equivalents due to the missing sha2 implementations.
Instead, we (fanquake, hebasto, TheCharlatan, and I) propose simply not migrating it to CMake and letting it end with v27. Any remaining use-cases could be handled in the future by libbitcoinkernel.
If there are any users currently using libbitcoinconsensus, please chime in with your use-case!
Edit: Corrected final release to be v27.

ACK 25dc87e6f8 - this library has very little, if any impactful real world usage. It has been entirely broken (on various platforms) for long periods of its existence, where nobody even noticed. Pruning this out to save porting, and starting anew with the kernel, is the sane thing to do.

* Various `const` issues with random access iterators. For example, a `const iterator` is different from a `const_iterator`, because the first one holds a mutable reference and must also return it without `const`. Also, `operator+` must be callable regardless of the iterator object's `const`-ness.
* When adding an offset to random access iterators, both `x+n` and `n+x` must be specified, see https://eel.is/c++draft/random.access.iterators#tab:randomaccessiterator
Fix all issues.

The test framework's p2p implementation currently sends out it's VERSION
message immediately after an inbound connection (i.e. TestNode outbound
connection) is made. This doesn't follow the usual protocol flow where
the initiator sends a version first, and the responders processes that
and only then responds with its own version message. Change that
accordingly by only sending immediate VERSION message for outbound
connections (or after v2 handshake for v2 connections, respectively),
and sending out VERSION messages as response for incoming VERSION
messages (i.e. in the function `on_version`) for inbound connections.
Note that some of the overruled `on_version` methods in functional tests
needed to be changed to send the version explicitly.
