Original commit message from CVS:
2005-07-12  Andy Wingo  <wingo@pobox.com>

* sys/v4l/gstv4lsrc.c (gst_v4lsrc_get_property)
(gst_v4lsrc_set_property, gst_v4lsrc_class_init, gst_v4lsrc_init)
(gst_v4lsrc_create): Re-add the copy-mode property, default to
TRUE to avoid deadlocks if an element holds on to our buffers.
