Lots of code refactoring, simplification and cleanup.
Lots of new unit-tests providing much higher code coverage.
All courtesy of rillig at netbsd.
Other significant changes:
o new read-only variable .SHELL which provides the path of the shell
used to run scripts (as defined by the .SHELL target).
o new debug option -dl: LINT mode, does the equivalent of := for all
variable assignments so that file and line number are reported for
variable parse errors.

from ChangeLog:
o filemon/filemon_dev.c: use O_CLOEXEC rather than extra syscall
o meta.c: target flagged .META is out-of-date if meta file missing
o cond.c: fix for compare_expression when doEval=0
o unit-tests/Makefile: rework
o filemon/filemon_dev.c: ensure filemon fd is closed on exec.

from ChangeLog:
(most of this by rillig@)
o lots of style and white-space cleanup
o lots more unit tests for variable modifiers
o simplified description of some functions
o str.c: refactor Str_Match
o var.c: debugging output for :@
constify VarModify parameter
fix :hash modifier on 16-bit platforms
remove unnecessary forward declarations
refactor ApplyModifier_SysV to have less indentation
simplify code for :E and :R
clean up code for :H and :T
refactor ApplyModifiers
* var.c: we need stdint.h on some platforms to get uint32_t
* unit-test/Makefile: we need to supress the specific error
for RE substitution error in modmisc, since it varies accross
different OS.

from ChangeLog:
o cond.c: do not eval unnecessary terms of conditionals.
o meta.c: report error if lseek in filemon_read fails
o str.c: performance improvement for Str_Match for multiple '*'
o dieQuietly: supress the failure output from make
when failing node is a sub-make or a sibling failed.
This cuts down greatly on unhelpful noise at the end of
build log. Disabled by -dj or .MAKE.DIE_QUIETLY=no
o unit test for :Or

Relevant items from ChangeLog:
o dir.c: cached_stats - don't confuse stat and lstat results.
o var.c: add :Or for reverse sort.

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

sjg@ committed the local patch previously committed upstream; pull it in to
vendor/ to ease any potential stress of future imports.

and apply if relative, and then use .PARSEFILE
for consistent result.
