Merge #16033: Hold cs_main when reading chainActive via getTipLocator(). Remove assumeLocked().
9402ef0739 Remove temporary method assumeLocked(). Remove LockingStateImpl. Remove redundant cs_main locks. (practicalswift)
593a8e8a2c wallet: Use chain.lock() instead of temporary chain.assumeLocked() (practicalswift)

Pull request description:

  Fixes #16028.

  Problem description:

  `LockAnnotation lock(::cs_main)` is a guarantee to the compiler thread analysis that `::cs_main` is locked (when it couldn't be determined otherwise).

  Despite being annotated with the locking guarantee ...

  65526fc866/src/interfaces/chain.cpp (L134-L138)

  ... `getTipLocator()` reads `chainActive` (via `::ChainActive()`) without holding `cs_main`.

  This can be verified by adding the following `AssertLockHeld(cs_main)`:

Merge #15870: wallet: Only fail rescan when blocks have actually been pruned
fa7e311e16 [doc] rpcwallet: Only fail rescan when blocks have been pruned (MarcoFalke)
aaaa57c2aa scripted-diff: Bump copyright headers in wallet (MarcoFalke)
faf3729242 wallet: Only fail rescan when blocks have actually been pruned (MarcoFalke)

Pull request description:

  This brings the behaviour of the import* calls closer to importmulti. After this change, the difference between importmulti and the other import* calls is

  * that in importmulti you can "opt-out" of scanning early blocks by setting a later timestamp.
  * that in importmulti the wallet will successfully import the data, but fail to rescan. Whereas in the other calls, the wallet will abort before importing the data.

Merge #15842: refactor: replace isPotentialtip/waitForNotifications by higher method
422677963a refactor: replace isPotentialtip/waitForNotifications by higher method (Antoine Riard)
edfe9438ca Add WITH_LOCK macro: run code while locking a mutex (Antoine Riard)

Pull request description:

  In Chain interface, instead of a isPotentialTip and a WaitForNotifications method, both used only once in CWallet::BlockUntilSyncedToCurrentChain, combine them in a higher WaitForNotificationsUpToTip method. Semantic should be unchanged, wallet wait for pending notifications to be processed unless block hash points to the current chain tip or a descendant.

5c759c73b2 [wallet] Move maxTxFee to wallet
This commit moves the maxtxfee setting to the wallet. There is only
one minor behavior change:

- an error message in feebumper now refers to -maxtxfee instead of
maxTxFee.

b874747b51 Remove access to node globals from wallet-linked code
Remove last few instances of accesses to node global variables from wallet
code. Also remove accesses to node globals from code in policy/policy.cpp that
isn't actually called by wallet code, but does get linked into wallet code.

This is the last change needed to allow bitcoin-wallet tool to be linked
without depending on libbitcoin_server.a, to ensure wallet code doesn't access
node global state and avoid bugs like

52b760fc6a [wallet] Schedule tx rebroadcasts in wallet
Removes the now-unused Broadcast/ResendWalletTransactions interface from
validationinterface.

The wallet_resendwallettransactions.py needs a sleep added at the start

ea961c3d72 Remove direct node->wallet calls in init.cpp
Route calls during node initialization and shutdown that would happen between a
node process and wallet processes through the serializable `Chain::Client`
interface, rather than `WalletInitInterface` which is now simpler and only
deals with early initialization and parameter interaction.

This commit mostly does not change behavior. The only change is that the
"Wallet disabled!" and "No wallet support compiled in!" messages are now logged
earlier during startup.
