4de4221ab4b645ff77503c777c9b195a962e9fa1 build: Check for std::atomic::exchange rather than std::atomic_exchange (Andrew Chow)
Pull request description:
Our usage of std::atomic is with it's own exchange function, not std::atomic_exchange. So we should be looking specifically for that function.
This removes the need for -latomic for riscv builds, which resolves a guix cross architecture reproducibility issue.

Pull request description:
This is part of the `libbitcoinkernel` project: #24303, https://github.com/bitcoin/bitcoin/projects/18
-----
This PR moves `{Dump,Load}Mempool` into its own `kernel/mempool_persist` module and introduces `ArgsManager` `node::` helpers in `node/mempool_persist_args`to remove the scattered calls to `GetBoolArg("-persistmempool", DEFAULT_PERSIST_MEMPOOL)`.
More context can be gleaned from the commit messages.
-----
One thing I was reflecting on as I wrote this was that in the long run, I think we should probably invert the validation <-> mempool relationship. Instead of mempool not depending on validation, it might make more sense to have validation not depend on mempool. Not super urgent since `libbitcoinkernel` will include both validation and mempool, but perhaps something for the future.

Our usage of std::atomic is with it's own exchange function, not
std::atomic_exchange. So we should be looking specifically for that
function.
Additionally, -pthread and -lpthread have an effect on whether -latomic
will be needed, so the atomics check needs to use these flags as well.
This will make the flags in use better match what is actually used when
linking.
This removes the need for -latomic for riscv builds, which resolves a
guix cross architecture reproducibility issue.

757216e31cac7dcd45e11b2a2c6148420b3b99da wallet: don't iter twice when getting the cached debit/credit amount (Antoine Poinsot)
Pull request description:
A small optimization i stumbled upon while looking at something else. Figured it could be worth a PR.
Instead of calling GetCachableAmount twice, which will result in
iterating through all the transaction txins/txouts and calling
GetDebit/GetCredit (which lock cs_wallet), just merge the filters and do
it once.

Also:
1. Have CChainState::LoadMempool and ::ThreadImport take in paths and
pass it through untouched to LoadMempool.
2. Make LoadMempool exit early if the load_path is empty.
3. Adjust the call to ::ThreadImport in ::AppInitMain to correctly pass
in an empty path if mempool persistence is disabled.
Not only does this increase coverage, it is also more correct in that
when ::LoadMempool is called with a mempool and chainstate, it calls
AcceptToMemoryPool with just the chainstate.
AcceptToMemoryPool will then act on the chainstate's mempool via
CChainState::GetMempool, which may be different from the mempool
originally passed to ::LoadMempool. (In this fuzz test's case, it
definitely is different)
Also, move DummyChainstate to its own file since it's now used by the
validation_load_mempool fuzz test to replace CChainState's m_mempool.
Watchonly wallets do not have any private keys to encrypt. It does not
make sense to encrypt such wallets, so disable the option to encrypt
them.
This avoids an assertion that can be hit when encrypting watchonly descriptor
wallets.
m_is_loaded/IsLoaded() doesn't actually indicate whether or not the
mempool was successfully, loaded, but rather if a load has been
attempted and did not result in a catastrophic ShutdownRequested.

Pull request description:
The return value of the `push*` helpers is never used, but important to determine if the operation was successful. One way to fix this would be to add the "nodiscard" attribute. However, this would make the code (and this diff) overly verbose for no reason.
So fix it by removing the never used return value. Also, fail verbosely in case of a programming mistake.

Pull request description:
This adds Miniscript support for Output Descriptors without any signing logic (yet). See the OP of #24147 for a description of Miniscript and a rationale of having it in Bitcoin Core.
On its own, this PR adds "watchonly" support for Miniscript descriptors in the descriptor wallet. A follow-up adds signing support.
A minified corpus of Miniscript Descriptors for the `descriptor_parse` fuzz target is available at https://github.com/bitcoin-core/qa-assets/pull/92.
The Miniscript descriptors used in the unit tests here and in #24149 were cross-tested against the Rust implementation at https://github.com/rust-bitcoin/rust-miniscript.
This PR contains code and insights from Pieter Wuille.

Prior to this commit, the peer was connected, and then the services and
connectivity fields in the CNode object were manually set. Instead, send
p2p `version` and `verack` messages, and have net_processing's internal
logic set the state of the node.
This ensures that the node's internal state is consistent with how it
would be set in the live code.
Prior to this commit, `dummyNode1.nServices` was set to `NODE_NONE`
which was not a problem since `CNode::fClient` and
`CNode::m_limited_node` are default initialised to false. Now that we
are doing the actual version handshake, the values of `fClient` and
`m_limited_node` are set during the handshake and cause the test to fail
if we do not set `dummyNode1.nServices` to a reasonable value
(NODE_NETWORK | NODE_WITNESS).
