[easytag/wip/taglib-mp4-cxx: 12/12] Remove auto pointer template

[David King <davidk src gnome org>]

commit 123d0090ddbe7bee68d922110cfbe13d98dec2af
Author: David King <amigadave amigadave com>
Date:   Fri Apr 11 11:29:07 2014 +0100

    Remove auto pointer template
    
    Additionally, unref the stream on destruction of GIO_InputStream, as
    closing the stream is not sufficient.
