Import bmake-20200517vendor/NetBSD/bmake/20200517

Changes since 20181221 are mostly portability related
hence the large gap in versions imported.

There are however some bug fixes, and a rework of filemon handling.
In NetBSD make/filemon/filemon_ktrace.c allows use of fktrace
and elimination of filemon(4) which has not had the TLC it needs.

FreeBSD filemon(4) is in much better shape, so bmake/filemon/filemon_dev.c
allows use of that, with a bit less overhead than the ktrace model.

Summary of changes from ChangeLog

	o str.c: empty string does not match % pattern
	  plus unit-test changes
	o var.c: import handling of old sysV style modifier using '%'
	o str.c: refactor brk_string
	o meta.c: meta_oodate, CHECK_VALID_META is too aggressive for CMD
	  a blank command is perfectly valid.
	o meta.c: meta_oodate, check for corrupted meta file
	  earlier and more often.
	* meta.c: meta_compat_parent check for USE_FILEMON
	  patch from Soeren Tempel
	o meta.c: fix compat mode, need to call meta_job_output()
	o job.c: extra fds for meta mode not needed if using filemon_dev
	o meta.c: avoid passing NULL to filemon_*() when meta_needed()
	  returns FALSE.
	o filemon/filemon_{dev,ktrace}.c: allow selection of
	  filemon implementation.  filemon_dev.c uses the kernel module
	  while filemon_ktrace.c leverages the fktrace api available in
	  NetBSD.  filemon_ktrace.c can hopefully form the basis for
	  adding support for other tracing mechanisms such as strace on
	  Linux.
	o meta.c: when target is out-of-date per normal make rules
	  record value of .OODATE in meta file.
	o parse.c: don't pass NULL to realpath(3)
	  some versions cannot handle it.
	o parse.c: ParseDoDependency: free paths rather than assert

plus more unit-tests

+	case insensitive filesystems just don't work if both
+	makefile and Makefile exist.
+	NOTE: bmake does not support cygwin and likely never will,
+	but if brave souls want to try it - help them out.

+	  We add --without-makefile to CONFIGURE_ARGS in this case.
+
+	* tweak bsd.after-import.mk (captures Makefile.config etc
+	  after import to FreeBSD for example) to cope with all the above.
