configure: automatically detect GStreamer API version.

Browse source 
Automatically detect GStreamer API version. The --with-gstreamer-api
configure option now defaults to "autodetect" and configure then tries
to derive the GStreamer API version from the highest version based on
what pkg-config --modversion would report.
