[gnome-autoar] Add new GQuark for libarchive-related error

[Ting-Wei Lan <lantw src gnome org>]

commit 6a3732447532036174879bd3f4e412dd6ddb94e6
Author: Ting-Wei Lan <lantw44 gmail com>
Date:   Thu Aug 29 17:26:41 2013 +0800

    Add new GQuark for libarchive-related error
    
    G_DEFINE_QUARK is used to define GQuark. The old global variables are removed.
    Error reported by libarchive use its own quark now. Quarks for autoar-extract
    and autoar-create are only used for error occurred within gnome-autoar.
