[glib] remove GSettings* from GSettingsKeyInfo

[Ryan Lortie <ryanl src gnome org>]

commit ca2004fe73ca853bc1f9ade6160c1b59d2865c67
Author: Ryan Lortie <desrt desrt ca>
Date:   Sun Nov 13 23:35:27 2011 +0100

    remove GSettings* from GSettingsKeyInfo
    
    This way GSettingsKeyInfo depends strictly on the information in the
    schema.  Pass the GSettings* around separately where we need it.
