Add unit test to test IPC method calls and type conversion between bitcoin c++
types and capnproto messages.
Right now there are custom type hooks in bitcoin IPC code, so the test is
simple, but in upcoming commits, code will be added to convert bitcoin types to
capnproto messages, and the test will be expanded.
fa825975b5 fuzz: Avoid timeout in process_messages (MarcoFalke)
Pull request description:
Reduce the number of messages per fuzz input. There should be no reason to have more messages than that.
This should also avoid timeouts, such as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=64548. CC https://github.com/bitcoin/bitcoin/issues/28812

Pull request description:
Now that the serialize framework ignores the serialize version and serialize type, everything related to it can be removed from the code.
This is the first step, removing dead code from the P2P stack. A different pull will remove it from the wallet and other parts.

Currently the damaging of input data for decryption (either ciphertext
or aad) only ever happens in the lower nibble within the byte at the
damage position, as the bit position for the `damage_val` byte was
calculated with `damage_bit & 3` (corresponding to `% 4`) rather than
`damage_bit & 7` (corresponding to the expected `% 8`).

Pull request description:
Most fuzz targets have an upper limit on the buffer size to avoid excessive runtime. Do the same for `script_flags` to avoid timeouts such as https://github.com/bitcoin/bitcoin/issues/28812#issuecomment-1824696971
Also, fix iwyu. Also, remove legacy `CDataStream`.

5e7cc4144b test: add unit test for CConnman::AddedNodesContain() (Jon Atack)
cc62716920 p2p: do not make automatic outbound connections to addnode peers (Jon Atack)
Pull request description:
to allocate our limited outbound slots correctly, and to ensure addnode
connections benefit from their intended protections.
Our addnode logic usually connects the addnode peers before the automatic
outbound logic does, but not always, as a connection race can occur. If an
addnode peer disconnects us and if it was the only one from its network, there
can be a race between reconnecting to it with the addnode thread, and it being
picked as automatic network-specific outbound peer. Or our internet connection
or router or the addnode peer could be temporarily offline, and then return
online during the automatic outbound thread. Or we could add a new manual peer
using the addnode RPC at that time.
The race can be more apparent when our node doesn't know many peers, or with
networks like cjdns that currently have few bitcoin peers.
When an addnode peer is connected as an automatic outbound peer and is the only
connection we have to a network, it can be protected by our new outbound
eviction logic and persist in the "wrong role".
Finally, there does not seem to be a reason to make block-relay or short-lived
feeler connections to addnode peers, as the addnode logic will ensure we connect
to them if they are up, within the addnode connection limit.
Fix these issues by checking if the address is an addnode peer in our automatic
outbound connection logic.

007d6f0e85 test: fix `AddNode` unit test failure on OpenBSD (Sebastian Falbesoner)
Pull request description:
On OpenBSD 7.4, the following check of the unit test `test_addnode_getaddednodeinfo_and_connection_detection` currently fails:
```
BOOST_CHECK(!connman->AddNode({/*m_added_node=*/"127.1", /*m_use_v2transport=*/true}));
```
The reason for that is that this OS seemingly doesn't support the IPv4 shorthand notation with omitted zero-bytes:
```
$ ping 127.1
ping: no address associated with name
```
As a simple fix, this PR skips the check for this with a pre-processor #if. On NetBSD and FreeBSD, `127.1` is resolved correctly to localhost and hence the test passes (thanks to vasild for verifying on the latter!).

`CBlockPolicyEstimator` will implement `CValidationInterface` and
subscribe to its notification to process transactions added and removed
from the mempool.
Re-delegate calculation of `validForFeeEstimation` from validation to fee estimator.
Also clean up the validForFeeEstimation arg thats no longer needed in `CTxMempool`.

If alignment of the PoolAllocator would be insufficient, then the test would fail. This also catches the issue with ARM 32bit,
where int64_t is aligned to 8 bytes but void* is aligned to 4 bytes. The test adds a check to ensure the pool has allocated
a minimum number of chunks
The nVersion field is unused, so remove it.
This is also required for future commits.
Also, add PushMessage aliases in PeerManagerImpl to make calling code
less verbose.
Co-Authored-By: Anthony Towns <aj@erisian.com.au>
This changes the PoolAllocator to default the alignment to the given type. This makes the code simpler, and most importantly
fixes a bug on ARM 32bit that caused OOM: The class CTxOut has a member CAmount which is an int64_t and on ARM 32bit int64_t
are 8 byte aligned which is larger than the pointer alignment of 4 bytes. So for CCoinsMap to be able to use the pool, we
need to use the alignment of the member instead of just alignof(void*).
This has the goal of prohibiting users from accidentally creating
runtime failures, e.g. by interacting with iterator_to with a copied
entry.
CTxMemPoolEntry is already implicitly not move-constructable. So be
explicit about this and use a std::list to collect the values in the
policy_estimator fuzz test instead of a std::vector.
