[libgrss] Add basic support for GObject Introspection.

[Roberto Guido <rguido src gnome org>]

commit 4c7232682e303c2fbb949724e5a4f98d90a7216d
Author: Simon Kågedal Reimer <skagedal gmail com>
Date:   Mon Jul 8 21:08:09 2013 +0200

    Add basic support for GObject Introspection.
    
    Following instructions at:
    https://wiki.gnome.org/GObjectIntrospection/AutotoolsIntegration
    
    More work is needed: Many warnings are generated by g-ir-scanner, and
    several methods are not introspected.
