a33cffbeab util: HelpExampleRpc formatting fixup (Jon Atack)
Pull request description:
Minor visual fixup of the HelpExampleRpc template; conforms to the JSON-RPC spec as per https://www.jsonrpc.org/specification#examples. (I'm... somewhat embarassed to open such a minor change, but this is what is shown in all the CLI/RPC help docs.)

NotifyEntryAdded never had any subscribers so can be removed.
Since ConnectTrace no longer subscribes to NotifyEntryRemoved, there are
now no subscribers.
The CValidationInterface TransactionAddedToMempool and
TransactionRemovedFromMempool methods can now provide this
functionality. There's no need for a special notifications framework for
the mempool.
ConnectTrace used to subscribe to the mempool's NotifyEntryRemoved
callback to be notified of transactions removed for conflict. Since
PerBlockConnectTrace no longer tracks conflicted transactions,
ConnectTrace no longer requires these notifications.
The only CValidationInterface client that cares about transactions that
are removed from the mempool because of CONFLICT is the wallet.
Start using the TransactionRemovedFromMempool method to notify about
conflicted transactions instead of using the vtxConflicted vector in
BlockConnected.

9220a0fdd0 tests: Add one specialized ProcessMessage(...) fuzzing binary per message type for optimal results when using coverage-guided fuzzing (practicalswift)
fd1dae10b4 tests: Add fuzzing harness for ProcessMessage(...) (practicalswift)
Pull request description:
Add fuzzing harness for `ProcessMessage(...)`. Enables high-level fuzzing of the P2P layer.
All code paths reachable from this fuzzer can be assumed to be reachable for an untrusted peer.
Seeded from thin air (an empty corpus) this fuzzer reaches roughly 20 000 lines of code.
To test this PR:
```
$ make distclean
$ ./autogen.sh
$ CC=clang CXX=clang++ ./configure --enable-fuzz \
--with-sanitizers=address,fuzzer,undefined
$ make
$ src/test/fuzz/process_message
…
```
Worth noting about this fuzzing harness:
* To achieve a reasonable number of executions per seconds the state of the fuzzer is unfortunately not entirely reset between `test_one_input` calls. The set-up (`FuzzingSetup` ctor) and tear-down (`~FuzzingSetup`) work is simply too costly to be run on every iteration. There is a trade-off to handle here between a.) achieving high executions/second and b.) giving the fuzzer a totally blank slate for each call. Please let me know if you have any suggestion on how to improve this situation while maintaining >1000 executions/second.
* To achieve optimal results when using coverage-guided fuzzing I've chosen to create one specialised fuzzing binary per message type (`process_message_addr`, `process_message_block`, `process_message_blocktxn `, etc.) and one general fuzzing binary (`process_message`) which handles all messages types. The latter general fuzzer can be seeded with inputs generated by the former specialised fuzzers.
Happy fuzzing friends!

2c52b59d0a Refactor rawtransaction's SignTransaction into generic SignTransaction function (Andrew Chow)
Pull request description:
Following #17261, the way to sign transactions, PSBTs, and messages was to use `GetSigningProvider()` and get a `SigningProvider` containing the private keys. However this may not be feasible for future `ScriptPubKeyMan`s, such as for hardware wallets. Instead of exporting a `SigningProvider` containing private keys, we need to pass these things into the `ScriptPubKeyMan` (via `CWallet`) so that they can do whatever is needed internally to sign them. This is largely a refactor as the logic of processing transactions, PSBTs, and messages for is moved into `LegacyScriptPubKeyMan` and `CWallet` instead of being handled by the caller (e.g. `signrawtransaction`).
To help with this, I've refactored the 3(!) implementations of a `SignTransaction()` function into one generic one. This function will be called by `signrawtransactionwithkey` and `LegacyScriptPubKeyMan::SignTransaction()`. `CWallet::CreateTransaction()` is changed to call `CWallet::SignTransaction()` which in turn, calls `LegacyScriptPubKeyMan::SignTransaction()`. Other `ScriptPubKeyMan`s may implement `SignTransaction()` differently.
`FillPSBT()` is moved to be a member function of `CWallet` and the `psbtwallet.cpp/h` files removed. It is further split so that `CWallet` handles filling the UTXOs while the `ScriptPubKeyMan` handles adding keys, derivation paths, scripts, and signatures. In the end `LegacyScriptPubKeyMan::FillPSBT` still calls `SignPSBTInput`, but the `SigningProvider` is internal to `LegacyScriptPubKeyMan`. Other `ScriptPubKeyMan`s may do something different.
A new `SignMessage()` function is added to both `CWallet` and `ScriptPubKeyMan`. Instead of having the caller (i.e. `signmessage` or the sign message dialog) get the private key, hash the message, and sign, `ScriptPubKeyMan` will now handle that (`CWallet` passes through to the `ScriptPubKeyMan`s as it does for many functions). This signing code is thus consolidated into `LegacyScriptPubKeyMan::SignMessage()`, though other `ScriptPubKeyMan`s may implement it differently. Additionally, a `SigningError` enum is introduced for the different errors that we expect to see from `SignMessage()`.
Lastly, `GetSigningProvider()` is renamed to `GetPublicSigningProvider()`. It will now only provide pubkeys, key origins, and scripts. `LegacySigningProvider` has it's `GetKey` and `HaveKey` functions changed to only return false. Future implementations should return `HidingSigningProvider`s where private keys are hidden.
Other things like `dumpprivkey` and `dumpwallet` are not changed because they directly need and access the `LegacyScriptPubKeyMan` so are not relevant to future changes.

Make sure that there are no errors set for an input after it is signed.
This is useful for when there are multiple ScriptPubKeyMans. Some may
fail to sign, but one may be able to sign, and after it does, we don't
want there to be any more errors there.
Not all ScriptPubKeyMans will be able to provide private keys,
but pubkeys and scripts should be. So only provide public-only
SigningProviders, i.e. ones that can help with Solving.
Instead of fetching a SigningProvider from ScriptPubKeyMan in order
to fill and sign the keys and scripts for a PSBT, just pass that
PSBT to a new FillPSBT function that does all that for us.

Optimize Expand by having BIP32PubkeyProvider also cache the parent
(or only) xpub within itself. Since Expand does not provide a read
cache, it is useful to internally cache this xpub to avoid re-deriving
the same xpub.
Also adds tests for this:
For ranged descriptors with unhardened derivation, we expect to
find parent keys in the cache but no child keys.
For descriptors containing an xpub but do not have unhardened derivation
(i.e. hardened derivation or single xpub with or without derivation),
we expect to find all of the keys in the cache, and the same
number of keys in the cache as in the SigningProvider.
For everything else (no xpub), nothing should be cached at all.
Have Expand, ExpandFromCache, and ExpandHelper take additional DescriptorCache
parameters. These are then passed into PubkeyProvider::GetPubKey which
also takes them as arguments.
Reading and writing to the cache is pushed down into GetPubKey. The old cache where
pubkeys are serialized to a vector is completely removed and instead xpubs are being
cached in DescriptorCache.

Pull request description:
A lot of places refer to `CWallet*`'s as `CWallet * const`, which translates to *"an immutable pointer to a mutable `CWallet` instance"*; this is
1. often not what the author meant, especially as a lot of these places do not at all modify the wallet object, and
2. confusing, as it tends to suggest that this is a proper way to refer to a constant `CWallet` instance.
This PR changes references to wallets to `const CWallet* const` whenever immutability is expected. This should result in no behavioral changes at all, and improved compile-time error checking.
Note from irc:
> <sipa> sounds good to me; this is the sort of change that as long as it compiles, the behavior shouldn't change
> <sipa> though in general it may lead to introducing automatic copying of objects sometimes (e.g. trying to std::move a const object will work, but generally result in a copy rather than an efficient move)
> <sipa> CWallet objects aren't copied or moved though

Pull request description:
Replacing boost functionality with C++11 stuff.
Motivated by #18227, but should stand alone. Changing from `boost::condition_var` to `std::condition_var` means `threadGroup.interrupt_all` isn't enough to interrupt `serviceQueue` anymore, so that means calling `stop()` before `join_all()` is needed. And the existing reverselock.h code doesn't work with sync.h's DebugLock code (because the reversed lock won't be removed from `g_lockstack` which then leads to incorrect potential deadlock warnings), so I've replaced that with a dedicated class and macro that's aware of our debug lock behaviour.

Changes from boost::chrono to std::chrono, boost::condition_var to
std::condition_var, boost::mutex to sync.h Mutex, and reverselock.h to
sync.h REVERSE_LOCK. Also adds threadsafety annotations to CScheduler
members.
Calling interrupt_all() will immediately stop the scheduler, so it's
safe to invoke stop() beforehand, and this removes the reliance on boost
to interrupt serviceQueue().
