Take advantage of new bmake feature to only consider Makefile.depend
as invalidating DIRDEPS_CACHE.
When bootstrapping allow more filtering via .MAKE.DEPENDFILE_BOOTSTRAP_SED
Move some comments back to where they make sense.
meta.sys.mk: add META_COOKIE_TOUCH and META_NOPHONY to better handle some
targets in meta mode vs non-meta mode.
Also use .MAKE.META.IGNORE_PATHS to ignore mtime of makefiles - which do
not matter in meta mode.
dirdeps.mk: move logic to handle -f dirdeps.mk to inside check
for first read of dirdeps.mk
Also fix handling of WITHOUT_DIRDEPS_BELOW
gendirdeps.mk: pass M2D_EXCLUDES to meta2deps
meta.autodep.mk: if we build with nofilemon, leave a cookie to
prevent updating dependencies until cleaned.

Archive member handling works again
meta mode, treat missing reads as for writes.
Update dirdeps.mk - much improved startup time.
Update meta.stage.mk - avoid ln when chmod required.
This allows most of the build to simply consider MK_META_MODE
Update to latest dirdeps.mk so we can do:
make -f dirdeps.mk bin/cat.i386

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.
