Merge branch 'nd/retire-fnmatch'

Replace our use of fnmatch(3) with a more feature-rich wildmatch. A handful patches at the bottom have been moved to nd/wildmatch to graduate as part of that branch, before this series solidifies. We may want to mark USE_WILDMATCH as an experimental curiosity a bit more clearly (i.e. should not be enabled in production environment, because it will make the behaviour between builds unpredictable). * nd/retire-fnmatch: Makefile: add USE_WILDMATCH to use wildmatch as fnmatch wildmatch: advance faster in <asterisk> + <literal> patterns wildmatch: make a special case for "*/" with FNM_PATHNAME test-wildmatch: add "perf" command to compare wildmatch and fnmatch wildmatch: support "no FNM_PATHNAME" mode wildmatch: make dowild() take arbitrary flags wildmatch: rename constants and update prototype
