This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
This change only affects behavior in the case where wallet last block processed
falls behind the chain tip. Previously listsinceblock might not have returned
all transactions up to the claimed "lastblock" value in this case, resulting in
race conditions and potentially missing transactions in cases where
listsinceblock was called in a loop like

This is a step toward removing the Chain::Lock class and reducing cs_main

This change only affects behavior in the case where wallet last block processed

last processed tip and the current node tip.
This is a step toward removing the Chain::Lock class and reducing cs_main

It also helps ensure the GUI display stays up to date in the case where the
node chain height runs ahead of wallet last block processed height.
FoundBlock class allows interfaces::Chain::findBlock to return more block
information without having lots of optional output parameters. FoundBlock class
is also used by other chain methods in upcoming commits.
There is mostly no change in behavior. Only exception is
CWallet::RescanFromTime now throwing NonFatalCheckError instead of
std::logic_error.
41b0baf43c gui: Handle WalletModel::unload asynchronous (João Barbosa)
ab31b9d6fe Fix wallet unload race condition (Russell Yanofsky)
Pull request description:
This PR consists in two fixes. The first fixes a concurrency issues with `boost::signals2`. The second fixes a wallet model destruction while it's being used.
From boost signal documentation at https://www.boost.org/doc/libs/1_72_0/doc/html/signals2/thread-safety.html:
> When a signal is invoked by calling signal::operator(), the invocation first acquires a lock on the signal's mutex. Then it obtains a handle to the signal's slot list and combiner. Next it releases the signal's mutex, before invoking the combiner to iterate through the slot list.
This means that `UnregisterValidationInterface` doesn't prevent more calls to that interface. The fix consists in capturing the `shared_ptr<CValidationInterface>` in each internal slot.
The GUI bug is fixed by using a `Qt::QueuedConnection` in the `WalletModel::unload` connection.

0933a37078 gui: Avoid Wallet::GetBalance in WalletModel::pollBalanceChanged (João Barbosa)
Pull request description:
Each 250ms the slot `WalletModel::pollBalanceChanged` is called which, at worst case, calls `Wallet::GetBalance`. This is a waste of resources since most of the time there aren't new transactions or new blocks. Fix this by early checking if cache is dirty or not.
The actual balance computation can still hang the GUI thread but that is tracked in #16874 and should be fixed with a solution similar to #17135.

Currently it's possible for ReleaseWallet to delete the CWallet pointer while
it is processing BlockConnected, etc chain notifications.
To fix this, unregister from notifications earlier in UnloadWallet instead of
ReleaseWallet, and use a new RegisterSharedValidationInterface function to
prevent the CValidationInterface shared_ptr from being deleted until the last
notification is actually finished.

1168394d75 [wallet] Notify conflicted transactions in TransactionRemovedFromMempool (John Newbery)
Pull request description:
These boost signals were added in #9371, before we had a `TransactionRemovedFromMempool` method in the validation interface. The `NotifyEntryAdded` callback was used by validation to build a vector of conflicted transactions when connecting a block, which the wallet was notified of in the `BlockConnected` CValidationInterface callback.
Now that we have a `TransactionRemovedFromMempool` callback, we can fire that signal directly from the mempool for conflicted transactions.
Note that #9371 was implemented to ensure `-walletnotify` events were fired for these conflicted transaction. We inadvertently stopped sending these notifications in #16624 (Sep 2019 commit 7e89994). We should probably fix that, but in a different PR.

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.
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.
CWallet::CanGetAddresses() is used to check whether the wallet has available or is able to produce keys for addresses. It uses the ScriptPubKeyMan::CanGetAddresses(), which in turn uses the const KeypoolCountExternalKeys() method, all which do counting and no modifications.
Also clean up forward other forward declarations in interfaces/wallet.h with !sort
Original motivation for this change was to fix a circular dependencies lint
error: "interfaces/chain.h -> interfaces/wallet.h -> psbt -> node/transaction
-> node/context -> interfaces/chain.h" from an earlier commit in this PR adding
a "interfaces/chain.h -> interfaces/wallet.h" include. Now, the wallet include
is no longer added, but it is still good to clean up the psbt include for
efficiency, and to sort the forward declarations.
Needed for future ScriptPubKeyMans which may need to create
SigningProviders dynamically and thus a normal pointer is not enough
This commit does not change behavior.

Pull request description:
For wallets with `WALLET_FLAG_DISABLE_PRIVATE_KEYS` this makes the watch-only balance available on the send screen (including coin selection). Instead of sending a transaction it generates a PSBT.
The user can take this PSBT and process it with [HWI](https://github.com/bitcoin-core/HWI) or put it an SD card for hardware wallets that support that.
The PSBT is copied to the clipboard. This was the easiest approach; we can add a dialog later to display it, as well as an option to save to disk.

We don't remove yet Chain locks as we need to preserve lock
order with CWallet one until swapping at once to avoid
deadlock failures (spotted by --enable-debug)
is exact match
In the next commit, we start using BlockConnected/BlockDisconnected
callbacks to establish tx depth, rather than querying the chain
directly.
Currently, BlockUntilSyncedToCurrentChain will return early if
the best block processed by the wallet is a descendant of the node'tip.
That means that in the case of a re-org, it won't wait for the
BlockDisconnected callbacks that have been enqueued during the re-org
but have not yet been triggered in the wallet.
Change BlockUntilSyncedToCurrentChain to only return early if the
wallet's m_last_block_processed matches the tip exactly. This ensures
that there are no BlockDisconnected or BlockConnected callbacks
in-flight.
To do so we update CValidationInterface::BlockDisconnect to take a
CBlockIndex pointing to the block being disconnected.
This new parameter will be use in the following commit to establish
wallet height.
