FatalError replaces what previously was the AbortNode function in
shutdown.cpp.
This commit is part of the libbitcoinkernel project and further removes
the shutdown's and, more generally, the kernel library's dependency on
interface_ui with a kernel notification method. By removing interface_ui
from the kernel library, its dependency on boost is reduced to just
boost::multi_index. At the same time it also takes a step towards
de-globalising the interrupt infrastructure.

11780f29e7c3f50fb7717fc98950ece9385d314b doc: BaseIndex sync behavior with empty datadir (James O'Beirne)
Pull request description:
Make a note about a potentially confusing behavior with `BaseIndex::m_synced`;
if the user starts bitcoind with an empty datadir and an index enabled,
BaseIndex will consider itself synced (as a degenerate case). This affects
how indices are built during IBD (relying solely on BlockConnected signals vs.
using ThreadSync()).

Replace CommitInternal method with CustomCommit and use interfaces::Chain
instead of CChainState to generate block locator.
This commit does not change behavior in any way, except in the
(m_best_block_index == nullptr) case, which was added recently in
https://github.com/bitcoin/bitcoin/pull/24117 as part of an ongoing attempt to
prevent index corruption if bitcoind is interrupted during startup. New
behavior in that case should be slightly better than the old behavior (skipping
the entire custom+base commit now vs only skipping the base commit previously)
and this might avoid more cases of corruption.
Replace Rewind method with CustomRewind and pass block hashes and
heights instead of CBlockIndex* pointers
This commit does not change behavior in any way.
Replace overriden index Init() methods that use the best block
CBlockIndex* pointer with pure CustomInit() callbacks that are passed
the block hash and height.
This gets rid of more CBlockIndex* pointer uses so indexes can work
outside the bitcoin-node process. It also simplifies the initialization
call sequence so index implementations are not responsible for
initializing the base class.
There is a slight change in behavior here since now the best block
pointer is loaded and checked before the custom index init functions are
called instead of while they are called.

1168394d759b13af68acec6d5bfa04aaa24561f8 [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.
