Pull request description:
This is the final step 🥳 of the serialization improvements extracted from #10785.
It converts the LimitedString wrapper to a new-style formatter, and updates the wallet and Qt code to use the new serialization framework. Finally all remaining old primitives are removed.

Pull request description:
Tracking our instrumented mutexes (`Mutex` and `RecursiveMutex` types) requires that all involved objects should not be destroyed until after their last use. On master (ec79b5f86b) we have two problems related to the object destroying order:
- the function-local `static` `lockdata` object that is destroyed at [program exit](https://en.cppreference.com/w/cpp/utility/program/exit)
- the `thread_local` `g_lockstack` that is destroyed at [thread exit](https://en.cppreference.com/w/cpp/language/destructor)
Both cases could cause UB at program exit in so far as mutexes are used in other static object destructors.

Code review ACK 90eb027204 because all the changes look correct and safe. But I don't know the purpose of commit 26c093a995 "Replace thread_local g_lockstack with a mutex-protected map (5/6)." It seems like it could have a bad impact on debug performance, and the commit message and PR description don't give a reason for the change.

Pull request description:
The global `g_chainman` has recently been introduced in #17737. The chainstate manager is primarily needed for the assumeutxo feature, but it can also simplify testing in the future.
The goal of this pull is to make the global chainstate manager internal to validation, so that all external code does not depend on globals and that unit or fuzz tests can pass in their (potentially mocked) chainstate manager.
I suggest reviewing the pull request commit-by-commit. It should be relatively straightforward refactoring that does not change behavior at all.

b59b4504ab have GenerateNewKey and DeriveNewChildKey take a CHDChain as an argument (Andrew Chow)
Pull request description:
Largely implements the suggestion from https://github.com/bitcoin/bitcoin/pull/17484#issuecomment-560845316.
After `sethdseed` is called, the CHDChain for the old seed is kept in the wallet. It is kept on the file as a new `inactivehdseed` record and in memory in a map `m_inactive_hd_seeds`. In `LegacyScriptPubKeyMan::MarkUnusedAddresses` we check each used key's metadata for whether it was derived from an inactive seed. If it is, we then check to see how many keys after that key were derived from the inactive seed. If that number does not match the keypool parameter, we derive more keys from the inactive seed until it does match. This way we won't miss transactions belonging to keys outside of the range of the keypool initially.
The indexes and internal-ness of a key is gotten by checking it's key origin data.
Because of this change, we no longer need to wait for IBD to finish before `sethdseed` can work so that check is also removed.
A test case for this is added as well which fails on master.

Followup to #18038 by amitiuttarwar which introduces the unbroadcast set: "a mechanism for the mempool to track locally submitted transactions" and decreases the frequency of rebroadcast from 10-15 minutes to 12-36 hours.
This PR addresses some of the outstanding TODOs building on top of it:
- remove `nLastResend` logic, which is used to ensure rebroadcast doesn't happen again if no new block has been mined (makes sense in 10-15 min period, but not necessary for 12-36 hour period). (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416826914))
- expose unbroadcast info via RPCs, for more informative queries and testing (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416837980))
- add sanity check to verify unbroadcast transactions still exist in mempool before rebroadcasting (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416861609))

c9a9ddb414 Set fDecryptionThoroughlyChecked based on whether crypted key checksums are valid (Andrew Chow)
a8334f7ac3 Read and write a checksum for encrypted keys (Andrew Chow)
Pull request description:
Adds a checksum to the encrypted key record in the wallet database so that encrypted keys can be checked for corruption on wallet loading, in the same way that unencrypted keys are. This allows for us to skip the full decryption of keys upon the first unlocking of the wallet in that session as any key corruption will have already been detected. The checksum is just the double SHA256 of the encrypted key and it is appended to the record after the encrypted key itself.
This is backwards compatible as old wallets will be able to read the encrypted key and ignore that there is more data in the stream. Additionally, old wallets will be upgraded upon their first unlocking (so that key decryption is checked before we commit to a checksum of the encrypted key) and a wallet flag set indicating that. The presence of the wallet flag lets us skip the full decryption as if `fDecryptionThoroughlyChecked` were true.
This does mean that the first time an old wallet is unlocked in a new version will take much longer, but subsequent unlocks will be instantaneous. Furthermore, corruption will be detected upon loading rather than on trying to send so wallet corruption will be detected sooner.

With encryption turned on by default for all wallets in consideration (#18889), I believe that wallet decryption will not be implemented ever or at least any time soon. So remove that TODO comment for now. If deemed important, a brainstorming issue can be opened instead.
Also remove some TODOs in the RPC console, which I don't understand. Maybe the gui was meant to show the debug log interactively? In any case, if deemed important, this should be filed as a brainstorming feature request, so that trade-offs of different solutions can be discussed.

691c817b34 Add util::Ref class as temporary alternative for c++17 std::any (Russell Yanofsky)
Pull request description:
This PR removes the `g_rpc_node` global, to get same benefits we see removing other globals and make RPC code more testable, modular, and reusable.
This uses a hybrid of the approaches suggested in #17548. Instead of using `std::any`, which isn't available in c++11, or `void*`, which isn't type safe, it uses a small new `util::Ref` helper class, which acts like a simplified `std::any` that only holds references, not values.
Motivation for writing this was to provide an simpler alternative to #18647 by Harris Brakmić (brakmic) which avoids some shortcomings of that PR (https://github.com/bitcoin/bitcoin/pull/18647#issuecomment-617878826)

to allow passing rpcwallet independently from the -rpcwallet user option, and to
move the logic to the top-level layer where most of the other option args are
handled.
to ConnectAndCallRPC() to be callable for individual connections.
This is needed for RPCs that need to be called and handled sequentially, rather
than alone or in a batch.
For example, when fetching the balances for each loaded wallet, -getinfo will
call RPC listwallets, and then, depending on the result, RPC getbalances.
It may be somewhat helpful to review this commit with `git show -w`.

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR consists of build changes only. It adds an `--enable-multiprocess` autoconf option (off by default and marked experimental), that builds new `bitcoin-node` and `bitcoin-gui` binaries. These currently function the same as existing `bitcoind` and `bitcoin-qt` binaries, but are extended in #10102 with IPC features to execute node, wallet, and gui functions in separate processes.
In addition to adding the `--enable-multiprocess` config flag, it also adds a depends package and autoconf rules to build with the [libmultiprocess](https://github.com/chaincodelabs/libmultiprocess) library, and it adds new travis configuration to exercise the build code and run functional tests with the new binaries.
The changes in this PR were originally part of #10102 but were moved into #16367 to be able to develop and review the multiprocess build changes independently of the code changes. #16367 was briefly merged and then reverted in #18588. Only change since #16367 has been dropping the `native_boost.mk` depends package which was pointed out to be no longer necessary in https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-596484337 and https://github.com/bitcoin/bitcoin/pull/18588#pullrequestreview-391765649
