[glib/wip/schemasource: 5/24] remove GSettings* from GSettingsKeyInfo

[Ryan Lortie <ryanl src gnome org>]

commit 1e1517689267618c7ccf3f82c72c63970a3ba8ee
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.
