The fsmonitor code has some platform-specific functions for which one or
more platforms implement noop or stub functions. We can't get rid of
these functions nor change their interface, since the point is to match
their equivalents in other platforms. But let's annotate their
parameters to quiet the compiler's -Wunused-parameter warning.

This creates a new fsmonitor-ll.h with most of the functions from
fsmonitor.h, though it leaves three inline functions where they were.
Two-thirds of the files that previously included fsmonitor.h did not
need those three inline functions or the six extra includes those inline
functions required, so this allows them to only include the lower level
header.
Diff best viewed with `--color-moved`.

Since this header showed up in some places besides just #include
statements, update/clean-up/remove those other places as well.
Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen
to include it first). This change exposed the violation and caused it
to stop building correctly; fix it by having it include
git-compat-util.h first, as per policy.

Dozens of files made use of gettext functions, without explicitly
including gettext.h. This made it more difficult to find which files
could remove a dependence on cache.h. Make C files explicitly include
gettext.h if they are using it.
However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an
include of gettext.h, it was left out to avoid conflicting with an
in-flight topic.

Starting with macOS 10.15 (Catalina), Apple introduced a new feature
called 'firmlinks' in order to separate the boot volume into two
volumes, one read-only and one writable but still present them to the
user as a single volume. Along with this change, Apple removed the
ability to create symlinks in the root directory and replaced them with
'synthetic firmlinks'. See 'man synthetic.conf'
When FSEevents reports the path of changed files, if the path involves
a synthetic firmlink, the path is reported from the point of the
synthetic firmlink and not the real path. For example:
Real path:
/System/Volumes/Data/network/working/directory/foo.txt
Synthetic firmlink:
/network -> /System/Volumes/Data/network
FSEvents path:
/network/working/directory/foo.txt
This causes the FSEvents path to not match against the worktree
directory.
There are several ways in which synthetic firmlinks can be created:
they can be defined in /etc/synthetic.conf, the automounter can create
them, and there may be other means. Simply reading /etc/synthetic.conf
is insufficient. No matter what process creates synthetic firmlinks,
they all get created in the root directory.
Therefore, in order to deal with synthetic firmlinks, the root directory
is scanned and the first possible synthetic firmink that, when resolved,
is a prefix of the worktree is used to map FSEvents paths to worktree
paths.

Provide a common interface for getting basic filesystem information
including filesystem type and whether the filesystem is remote.
Refactor existing code for getting basic filesystem info and detecting
remote file systems to the new interface.
Refactor filesystem checks to leverage new interface. For macOS,
error-out if the Unix Domain socket (UDS) file is on a remote
filesystem.
