-Context:
If `AddToWallet` db write fails, the method returns a wtx nullptr without
removing the recently added transaction from the wallet's map.
-Problem:
When a db write error occurs, `AddToWalletIfInvolvingMe` return false even
when the tx is on the wallet's map already --> which makes `SyncTransaction`
skip the `MarkInputsDirty` call --> which leads to a wallet invalid state
where the inputs of this new transaction are not marked dirty, while the
transaction that spends them still exist on the in-memory wallet tx map.
Plus, as we only store arriving transaction inside `AddToWalletIfInvolvingMe`
when we synchronize/scan blocks from the chain and nowhere else, it makes sense
to treat the tx db write error as a runtime error to notify the user about the
problem. Otherwise, the user will lose all the not stored transactions after a
wallet shutdown (without be able to recover them automatically on the next
startup because the chain sync would be above the block where the txs arrived).
2315830491b2cfa6b6e3e277700238e5ac92a8e0 fuzz: Fix assert bug in txorphan target (chinggg)
Pull request description:
Fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=48914.
It is possible to construct big tx that got rejected in `AddTx`, so we cannot assume tx will be added successfully. We can only guarantee tx will not be added if orphanage already has it.

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.

We currently expose a method to get the signing providers, which allows
to infer a descriptor from the scriptPubKey. But in order to identify
"on" what descriptor a coin was received, we need access to the
descriptors that were imported to the wallet.

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).
As UniValue provides several constructors for integral types, the
compiler is unable to select one if the passed type does not exactly
match. This is unintuitive for developers and forces them to write
verbose and brittle code.
For example, there are many places where an unsigned int is cast to a
signed int. While the cast is safe in practice, it is still needlessly
verbose and confusing as the value can never be negative. In fact it
might even be unsafe if the unsigned value is large enough to map to a
negative signed one.
Miniscript descriptors are defined under P2WSH context (either `wsh()`
or `sh(wsh())`).
Only sane Miniscripts are accepted, as insane ones (although valid by
type) can have surprising behaviour with regard to malleability
guarantees and resources limitations.
As Miniscript descriptors are longer and more complex than "legacy"
descriptors, care was taken in error reporting to help a user determine
for what reason a provided Miniscript is insane.
