* pango/src/pango_methods.defs: Regenerated with h2defs.py
* pango/src/pango_extra_objects.defs: Added some object definitions to help
the documentation generator, avoiding warnings about not being able to
transform C function names into C++ function names. I did the same thing in
gtkmm a few months ago.
* pango/src/filelist.am: Mention the new files.
* pango/src/pango.defs: Include the new file.
