In these cases the value assigned by the switch block is used directly
rather than returned. Mark the initial/default value as used so
clang-SA doesn't complain about it.

Rather than running selected source files through the preprocessor and a
bunch of perl regex'ing to get the list of all DEFUNs, use the data
collected in frr.xref.
This not only eliminates issues we've been having with preprocessor
failures due to nonexistent header files, but is also much faster.
Where extract.pl would take 5s, this now finishes in 0.2s. And since
this is a non-parallelizable build step towards the end of the build
(dependent on a lot of other things being done already), the speedup is
actually noticeable.
Also files containing CLI no longer need to be listed in `vtysh_scan`
since the .xref data covers everything. `#ifndef VTYSH_EXTRACT_PL`
checks are equally obsolete.

Not much to say here, user docs are coming up in a separate commit.
RFC5424 and (systemd's) journald allow passing structured key-value
data. This stuffs the metadata we have available into there.
The "does the system syslogd support RFC5424" question is unfortunately
not easily answered, so we can only give an affirmative answer on NetBSD
5.0+ or FreeBSD 12+.
