[grilo] core: update serialize/unserialize functions

[Juan A. Suárez Romero <jasuarez src gnome org>]

commit 96cdec89f6da97206617a4ef302199c523ed155f
Author: Juan A. Suarez Romero <jasuarez igalia com>
Date:   Tue Dec 15 17:35:33 2015 +0100

    core: update serialize/unserialize functions
    
    Use the new flatten GrlMedia to serialize/unserialize.
    
    We keep the same format as in previous versions, except for the containers,
    which are now serialized as "grlcontainer" instead of "grlbox".
