[RFC] Use glib-2.0 exclusively

[Dan Nicholson]

I've been working on a branch to make pkg-config use glib2 exclusively.
I posted it on fd.o if anyone wants to have a go.

  git://anongit.freedesktop.org/~dbn/pkg-config glib2

There are two big features in this work:

 * Bundle glib2 instead of glib1 since glib1 is dead and we can make use
   of glib2 API.
 * Replace popt usage with glib2 and drop popt from pkg-config.

I decided to bundle glib2 slightly differently than glib1. There is now
a snapshot + patches directly in the pkg-config repo instead of
replaying that sequence each time during autogen.sh. It would be up to
the maintainer to update the snapshot when necessary. A script is
available to ease that work.

All the tests pass on the branch, although I haven't tried using it as
my system pkg-config yet. Below is the commit log, but I removed the
diffstat because it was too huge. The shortstat is a bit inflated since
it doesn't include the removal of the glib-1.2.10 tarball.

Let me know if you have any comments. I've cc'd Matthias since I can't
think of a person who knows glib and pkg-config more than him. :)
