Implement mpeg2 garbage filter in pvrusb2
From: Mike Isely <isely@pobox.com>
The PVR USB2 hardware seems to like emitting some garbage data before
real stream data appears. This problem has been present all along,
but with the older 29xxx model series it was benign because the
garbage data in question didn't seem to bother mpeg2 players. But
with the 24xxx model series, the garbage data includes what looks like
a corrupted mpeg2 packet, which kills mythtv and ffmpeg. This fix
causes incoming stream data to be discarded until valid mpeg2 data is
seen.
