[gssdp] Create vapi file from introspection

[Jens Georg <jensgeorg src gnome org>]

commit 6ea8f8848d245863deb6b40c8efea8f9fed37f83
Author: Jens Georg <mail jensge org>
Date:   Thu Feb 23 14:02:44 2012 +0200

    Create vapi file from introspection
    
    The skipping of the error-domain in .metadata and the -custom.vala file
    are necessary due to https://bugzilla.gnome.org/show_bug.cgi?id=670673.
    
    They can be removed once that is fixed
