gst/qtdemux/qtdemux.c: Parse version 2 sample descriptions.

Browse source 
Original commit message from CVS:
* gst/qtdemux/qtdemux.c: (qtdemux_parse), (qtdemux_dump_unknown),
(qtdemux_parse_trak), (gst_qtdemux_handle_esds):
Parse version 2 sample descriptions.
Don't #define gst_util_dump_mem(), use something more
specific instead to avoid confusion.
