meta2deps - add checks to detect truncated/corrupted filemon data
(only known to happen on Linux hosts), to ensure we do not auto
update dependencies based on incomplete data.
meta.stage.mk adds STAGE_SHLIB_LINKS_FILTER and STAGE_LINK_AS_*
We also allow for hosts where egrep is deprecated for grep -E

Latest dirdeps.mk is far more efficient when generating
DIRDEPS_CACHE.
Update dirdeps-options.mk to allow DEP_RELDIR to factor
into option processing. This is not very interesting if all
options are global.
dirdeps.mk: simplify computation of qualified vs unqualified dirdeps.
Note the importance of avoiding unresolved variables in DIRDEPS
Fix DIRDEP_LOADAVG_REPORT - expr(1) fails if expression evaluates to 0
Trim ${SRCTOP}/ from debug etc messages to make comparison easier.
Include number of DIRDEPS in debug output.
Trim ${SRCTOP}/ when exporting to env while building DIRDEPS_CACHE
to help avoid env exhaustion.
Use DIRDEPS_ALL_MACHINES_FILTER to better handle ALL_MACHINES
in complex build environments.
dirdeps-options.mk: use separate .undef for each variable
dirdeps-targets.mk: allow for '.' in DIRDEPS_TARGETS_DIRS
meta.autodep.mk: leverage ${.SUFFIXES} if we can.
meta.sys.mk: allow use in META_MODE vs DIRDEPS_BUILD
meta2deps.py: compute a list of dirdep extensions that map to current
TARGET_SPEC to avoid confusion.

dirdeps.mk and meta.autodep.mk will now look for
Makefile.depend.options
to handle optional dependencies, the work is all done by
dirdeps-options.mk
Also update to latest meta.stage.mk and gendirdeps.mk
