This PR intends to resolve#15227.
"configure --debug-enabled" enables "#ifdef DEBUG_LOCKORDER".
Then "lockdata" (in sync.cpp) will be initialized same as other
static objects.
But unfortunately, lockdata.push_lock() was called before its
initialization (via initializing signatureCache which is declared
in script/sigcache.cpp) on macOS.
This PR apply the "Construct On First Use Idiom" to "lockdata"
to prevent it.

zcash: Not an actual locking fix; just eliminates unnecessary recursive
zcash: locking (which is a long-term goal).

This resolves an issue where getrawmempool() can race mempool
notification signals. Intuitively we use mempool.cs as a "read
lock" on the mempool with cs_main being the write lock, so holding
the read lock intermittently while doing write operations is
somewhat strange.
This also avoids the introduction of cs_main in getrawmempool()
which reviewers objected to in the previous fix in #12273

The HTTP worker thread counter, as well as the RAII object that was used
to maintain it, is unused now, so can be removed.

This function, which waits for all threads to exit, is no longer needed
now that threads are joined instead.

This prevents a potential race condition if control flow ends up in
`ShutdownHTTPServer` before the thread gets to `queue->Run()`,
deleting the work queue while workers are still going to use it.
Meant to fix#12362.

A rare race condition may trigger while awaiting the body of a message, see
upsteam commit 5ff8eb26371c4dc56f384b2de35bea2d87814779 for details.
This may fix some reported rpc hangs/crashes.

CWallet::MarkConflicted may acquire the cs_main lock after
CWalletDB::LoadWallet acquires the cs_wallet lock during wallet initialization.
(CWalletDB::LoadWallet calls ReadKeyValue which calls CWallet::LoadToWallet
which calls CWallet::MarkConflicted). This is the opposite order that cs_main
and cs_wallet locks are acquired in the rest of the code, and so leads to
POTENTIAL DEADLOCK DETECTED errors if bitcoin is built with -DDEBUG_LOCKORDER.
This commit changes CWallet::LoadWallet (which calls CWalletDB::LoadWallet) to
acquire both locks in the standard order. It also fixes some tests that were
acquiring wallet and main locks out of order and failed with the new locking in
CWallet::LoadWallet.

Link with ntdll library on Windows
This fixes a regression for builds targeting Windows introduced in #4947. It also includes a minor cleanup to fix a build warning.
closes#5051
This fixes#5051, which is a regression caused by the dependency on the ntapi crate
