[gconfmm] Fix compiler warnings.

[Murray Cumming <murrayc src gnome org>]

commit cb4ada9fcb05da3a9928d94adfdcf6b204555833
Author: Murray Cumming <murrayc murrayc com>
Date:   Thu Jun 3 21:48:40 2010 +0200

    Fix compiler warnings.
    
    * gconf/gconfmm/callback.cc:
    * gconf/src/changeset.ccg: Comment out unused method parameters.
    * gconf/src/entry.hg: Use gconf_entry_unref() instead of gconf_entry_free(),
    which is deprecated, though one just calls the other, and neither are really
    documented. It's still not a registered boxed type.
