pkg-config with internal glib

[Dan Nicholson]

I've integrated a glib-2.32.0 snapshot back into code and plan on
supporting stable releases as they become available. The default is
still to use a system installed glib, but you can use the internal
copy with the --with-internal-glib option. You can review the patches
in my git directory.

I've also made a temporary tarball that has all the autotools
integration. If you're one of the people having bootstrap issues,
please try to the tarball below and let me know if it works for you.

I tried to streamline the embedded glib, but there are still some
unnecessary configure checks going on. I think the only non-libc
dependency needed is probably gettext. The glib APIs needing other
external dependencies were stripped out.
