ext/xine/: add first version of xine plugin wrapper. Currently only wraps the

Original commit message from CVS:
2004-02-20  Benjamin Otte  <otte@gnome.org>

* ext/xine/Makefile.am:
* ext/xine/gstxine.h:
* ext/xine/xine.c:
* ext/xine/xineaudiodec.c:
* ext/xine/xinecaps.c:
add first version of xine plugin wrapper. Currently only wraps the
QDM2 win32 DLL, and even that only in proof-of-concept quality.
* configure.ac:
* ext/Makefile.am:
add xine plugin wrapper, disabled by default. Use --enable-xine to
build. Note that it'll segfault on gst-register if you don't remove
the goom and tvtime post plugins from xine.
* gst/qtdemux/qtdemux.c: (gst_qtdemux_handle_sink_event),
(qtdemux_parse), (qtdemux_parse_trak), (qtdemux_audio_caps):
add extradata parsing for QDM2.
change around debugging prints.
