* gst/qtdemux/qtdemux.c: (gst_qtdemux_find_keyframe),
(gst_qtdemux_find_segment), (gst_qtdemux_perform_seek),
(gst_qtdemux_seek_to_previous_keyframe),
(gst_qtdemux_activate_segment), (gst_qtdemux_loop): Make sure we
we don't clip the segment's stop using the main segment duration
as
that could crop quite some video frames. Make reverse playback
support
more robust and support edit lists. Support seeking to the last
frame,
and fix reverse looping playback. Add some debugging.
* win32/common/config.h: Updated.
