Initial commit of the built-in libgd based on GD-2.0.1

This initial checkin has no changes to any of the libgd code so it can
be used as a basis for diffs.  It also will not build currently because
of this.  The PHP gd checks need to be incorporated along with a bit of
other config magic.  It also shouldn't break the build and will only
take effect if you use --with-gd=php right now.
