There are no changes to behavior. Changes in this commit are all additions, and
are easiest to review using "git diff -U0 --word-diff-regex=." options.
Motivation for this change is to keep util functions with really generic names
like "Split" and "Join" out of the global namespace so it is easier to see
where these functions are defined, and so they don't interfere with function
overloading, especially since the util library is a dependency of the kernel
library and intended to be used with external code.
The key module's functionality is not used by the kernel library, but
currently kernel users are still required to initialize the key module's
`secp256k1_context_sign` global as part of the `kernel::Context` through
`ECC_Start`.
The extra `bilingual_str` argument of the fatal error notifications and
`node::AbortNode()` is often unused and when used usually contains the
same string as the message argument. It also seems to be confusing,
since it is not consistently used for errors requiring user action. For
example some assumeutxo fatal errors require the user to do something,
but are not translated.
So simplify the fatal error and abort node interfaces by only passing a
translated string. This slightly changes the fatal errors displayed to
the user.
Also de-duplicate the abort error log since it is repeated in noui.cpp.
Use SignalInterrupt object instead. There is a slight change in behavior here
because the previous StartShutdown code used to abort on failure and the
new code logs errors instead.
This change drops the last kernel dependency on shutdown.cpp. It also adds new
hooks for libbitcoinkernel applications to be able to interrupt kernel
operations when the chain tip changes.
This is a refactoring that does not affect behavior. (Looking at the code it
can appear like the new break statement in the ActivateBestChain function is a
change in behavior, but actually the previous StartShutdown call was indirectly
triggering a break before, because it was causing m_chainman.m_interrupt to be
true. The new code just makes the break more obvious.)
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.

This is done in addition with the following commit. Both have the goal
of getting rid of direct calls to AbortNode from kernel code. This extra
flushError method is added to notify specifically about errors that
arrise when flushing (syncing) block data to disk. Unlike other
instances, the current calls to AbortNode in the blockstorage flush
functions do not report an error to their callers.

Since the kernel library no longer depends on the system file, move it
to the common library instead in accordance to the diagram in
doc/design/libraries.md.

The DoWarning and AlertNotify functions are moved out of the
validation.cpp file, which removes its dependency on interface_ui as
well as util/system.

Define a new kernel notification class with virtual methods for
notifying about internal kernel events. Create a new file in the node
library for defining a function creating the default set of notification
methods such that these do not need to be re-defined all over the
codebase. As a first step, add a `blockTip` method, wrapping
`uiInterface.NotifyBlockTip`.
