correctly, fix build in lots of cases, since there is a HUGE number of
things gst will try to pick up.
fix the framework for MULTI_PACKAGES to not do insane stuff, and simplify
the main Makefile greatly.
Set up SHARED_ONLY.
Some more clean-up to do.
Someone will have to come up with descriptions and comments more accurate,
and do more plugins testing...
the FULLPKGPATH, thus providing changes to packing-lists which shouldn't
happen, and making update more difficult.
Accordingly, bump all pkgnames with PSEUDO_FLAVORS, and provide an
update @pkgpath for the bug for most of them (left out the ones with 3
or 4 pseudo flavors for space constraints...)
