fac96d0265 p2p: Limit m_block_inv_mutex (MarcoFalke)
Pull request description:
Keeping the lock longer than needed is confusing to reviewers and thread analysis. For example, keeping the lock while appending tx-invs, which requires the mempool lock, will tell thread analysis tools an incorrect lock order of `(1) m_block_inv_mutex, (2) pool.cs`.

9096b13a47 net: remove unnecessary check of CNode::cs_vSend (Vasil Dimov)
Pull request description:
It is not possible to have a node in `CConnman::vNodesDisconnected` and
its reference count to be incremented - all `CNode::AddRef()` are done
either before the node is added to `CConnman::vNodes` or while holding
`CConnman::cs_vNodes` and the object being in `CConnman::vNodes`.
So, the object being in `CConnman::vNodesDisconnected` and its reference
count being zero means that it is not and will not start to be used by
other threads.
So, the lock of `CNode::cs_vSend` in `CConnman::DisconnectNodes()` will
always succeed and is not necessary.
Indeed all locks of `CNode::cs_vSend` are done either when the reference
count is >0 or under the protection of `CConnman::cs_vNodes` and the
node being in `CConnman::vNodes`.

Pull request description:
As described in https://github.com/bitcoin/bitcoin/issues/20620 multisigs are currently limited to 16 keys in descriptors and RPC helpers, even for P2WSH and P2SH-P2WSH.
This adds support for multisig with up to 20 keys (which are already standard) for Segwit v0 context for descriptors (`wsh()`, `sh(wsh())`) and RPC helpers.

Allow RPC users to opt-in to unsafe inputs when funding a raw transaction.
Applications that need to manage a complex RBF flow (such as lightning
nodes using anchor outputs) are very limited if they can only use safe inputs.

Pull request description:
This is part of the coinstats index project tracked in #18000
While the review of the new UTXO set hash algorithm (MuHash) takes longer recently #19328 was merged which added the possibility to run `gettxoutsetinfo` with a specific hash type. As the first type it added `hash_type=none` which skips the hashing of the UTXO set altogether. This alone did not make `gettxoutsetinfo` much faster but it allows the use of an index for the remaining coin statistics even before a new hashing algorithm has been added. Credit to Sjors for the idea to take this intermediate step.
Features summary:
- Users can start their node with the option `-coinstatsindex` which syncs the index in the background
- After the index is synced the user can use `gettxoutsetinfo` with `hash_type=none` or `hash_type=muhash` and will get the response instantly out of the index
- The user can specify a height or block hash when calling `gettxoutsetinfo` to see coin statistics at a specific block height

This reverts commit eac6a3080d ("refactor:
Rework asmap Interpret to avoid ptrdiff_t"), because it is UB to form a
past-the-end iterator, even if it is never dereferenced.
Then fix the compiler warning in a different way:
Instead of comparing an uint32_t against a signed ptrdiff_t, just
promote both to a type that can represent both types.
Even though in this case the ptrdiff_t should never hold a negative
value, the overhead from promotion should be negligible.

This increase the maximum number of pubkeys to 20 (valid in P2WSH and
P2SH-P2WSH) and only checks the redeemScript doesn't exceed
MAX_SCRIPT_ELEMENT_SIZE for P2SH, as this checked is removed under
Segwit context.
Signed-off-by: Antoine Poinsot <darosior@protonmail.com>
We were previously ruling out 17-20 pubkeys multisig, while they are
only invalid under P2SH context.
This makes multisigs with up to 20 keys be detected as valid by the
solver. This is however *not* a policy change as it would only apply
to bare multisigs, which are already limited to 3 pubkeys.
Note that this does not change the sigOpCount calculation (as it would
break consensus). Therefore 1-16 keys multisigs are counted as 1-16 sigops
and 17-20 keys multisigs are counted as 20 sigops.

This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).

This PR adds basic process spawning and IPC method call support to `bitcoin-node` executables built with `--enable-multiprocess`[*].
These changes are used in https://github.com/bitcoin/bitcoin/pull/10102 to let node, gui, and wallet functionality run in different processes, and extended in https://github.com/bitcoin/bitcoin/pull/19460 and https://github.com/bitcoin/bitcoin/pull/19461 after that to allow gui and wallet processes to be started and stopped independently and connect to the node over a socket.
These changes can also be used to implement new functionality outside the `bitcoin-node` process like external indexes or pluggable transports (https://github.com/bitcoin/bitcoin/pull/18988). The `Ipc::spawnProcess` and `Ipc::serveProcess` methods added here are entry points for spawning a child process and serving a parent process, and being able to make bidirectional, multithreaded method calls between the processes. A simple example of this is implemented in commit "Add echoipc RPC method and test."
Changes in this PR aside from the echo test were originally part of #10102, but have been split and moved here for easier review, and so they can be used for other applications like external plugins.
Additional notes about this PR can be found at https://bitcoincore.reviews/19160
[*] Note: the `--enable-multiprocess` feature is still experimental, and not enabled by default, and not yet supported on windows. More information can be found in [doc/multiprocess.md](https://github.com/bitcoin/bitcoin/blob/master/doc/multiprocess.md)
