[tracker/tracker-0.10] build: new --with-gstreamer-backend=[tagreadbin, decodebin2, discoverer]

[Martyn James Russell <mr src gnome org>]

commit 77307c9f855c5d80c4fd707061a81ecbff886fb7
Author: Aleksander Morgado <aleksander lanedo com>
Date:   Tue Jul 12 16:05:07 2011 +0200

    build: new --with-gstreamer-backend=[tagreadbin,decodebin2,discoverer]
    
    Allows selecting among 'tagreadbin', 'decodebin2' and 'discoverer', and replaces
    the previous --enable-gstreamer-tagreadbin boolean switch.
    
    Also makes sure that discoverer is requested when enabling the GUPnP-DLNA
    enabled GStreamer extractor
