f65e57124f ffplay: flush video filters on seek 
Actually we just re-create the filters, since there is no way to flush them.
Fixes hangup with yadif filter on seeking forward caused by a filtered frame
with a pts before the seek.

1427c6842d ffplay: use videoq.serial to detect obsolete frames 
Previously VideoPicture->skip was used for that, using videoq.serial enables us
to detect obsolete frames right after pushing flush_pkt to the packet queue, so
we don't have to wait for the decoder thread to pop the flush packet anymore.

This is good because until now a full video picture queue may have blocked the
decoder thread.

940b8b5861 h264: avoid pointless copying of ref lists 
ref_list is constructed from other fields per slice when needed, so do
not copy it for both frame and slice threading.
default_ref_list is constructed per frame and still needs to be copied
to per-slice contexts for slice threading, but a copy is not needed for
frame threading.

The mask `x && (1 << y)' is incorrect and always yields true.

The correct form should be `x & (1 << y)'.

e33db35b4a theora: Skip zero-sized headers 
This fixes a regression since d9cf5f51 with theora over RTP
(possibly with other variants of theora as well).

In theora over RTP, the second of the 3 headers turns out to be
0 bytes long, which prior to d9cf5f51 worked just fine. After
d9cf5f51, reading from the bitstream reader fails (since the reader
wasn't initialized but returned an error if initialized with 0 bits).
