Andy Wingo 84761c6a82 sys/v4l/v4lsrc_calls.*: Remove sync-related stuff.
Original commit message from CVS:
2005-07-07  Andy Wingo  <wingo@pobox.com>

* sys/v4l/v4lsrc_calls.h:
* sys/v4l/v4lsrc_calls.c: Remove sync-related stuff.
(gst_v4lsrc_get_fps_list): Moved here from gstv4lsrc.c.
(gst_v4lsrc_buffer_new): Totally derive from GstBuffer.

* sys/v4l/v4l_calls.h: Cast to V4lElement.
* sys/v4l/v4l_calls.c: Header loc fixen, don't load mjpeg, all
v4lelements are sources.

* sys/v4l/gstv4lxoverlay.h:
* sys/v4l/gstv4lxoverlay.c:
* sys/v4l/gstv4ltuner.h:
* sys/v4l/gstv4ltuner.c: Header loc fixen.

* sys/v4l/gstv4lsrc.h:
* sys/v4l/gstv4lsrc.c: Crucial GPL update. Clean up a bit, port to
PushSrc/BaseSrc. Removed most sync-related properties, videorate
or something should handle that. Made a live source.

* sys/v4l/gstv4lelement.h:
* sys/v4l/gstv4lelement.c: Derive from GstPushSrc. No more
signals. Some cleanups.

* sys/v4l/gstv4lcolorbalance.h: Interface header update.

* sys/v4l/gstv4l.c: Don't register v4lelement, or the jpeg/mjpeg
stuff.

* sys/v4l/Makefile.am: Build everything except the jpeg/mjpeg
stuff.

* sys/Makefile.am (SUBDIRS): Hit the V4L crack pipe.
