If we do this, let's have the defs in GNOME's cvs. I guess we could have
a gnome-defs module, with sub-directories for each GNOME module, such as
gtk+, atk, libgnomeui, etc.

gtkmm uses them. For the methods, we use the output of
pygtk/codegen/h2defs.py almost unchanged. The other stuff needs to be
generated with different utilities, so we keep them separate.

Sharing of .defs should be a reasonable aim for the GNOME 2.8 cycle.
