Merge commit 'ee914ef902ae018bd4f67192832120f9bf05651f' into new_merge

Merge bmake-20210110

Quite a lot of churn on style, but lots of
good work refactoring complicated functions
and lots more unit-tests.
Thanks mostly to rillig at NetBSD

Some interesting entries from ChangeLog

o .MAKE.{UID,GID} represent uid and gid running make.

o allow env var MAKE_OBJDIR_CHECK_WRITABLE=no to skip writable
checks in InitObjdir. Explicit .OBJDIR target always allows
read-only directory.

o add more unit tests for META MODE

Change-Id: I464fd4c013067f0915671c1ccc96d2d8090b2b9c

Update to bmake-20201101

Lots of new unit-tests increase code coverage.

Lots of refactoring, cleanup and simlpification to reduce
code size.

Fixes for Bug 223564 and 245807

Updates to dirdeps.mk and meta2deps.py

Update to bmake-20200710

Key changes include reduced noise at end of failed build log
and avoid evaluation of unnecessary terms in conditionals.
In META MODE; a target flagged .META is out-of-date if meta file
is missing

MFC after: 1 week

Merge 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o meta.c: when target is out-of-date per normal make rules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
