bc909626b0 twinvq: move all bitstream reading into single place 
This is required for the future addition of VoxWare MetaSound decoder, for its
functions are mostly the same but bitstream reader is completely different
and bitstream format is slightly different too.

a22ae9f0c5 mpegts: Remove one 64-bit integer modulus operation per packet 
The common case of the pointer having increased by one packet (which results
in no change to the modulus) can be detected with a 64-bit subtraction,
which is far cheaper than a division on many platforms.

c84ea750cf mpegts: Make discard_pid() faster for single-program streams 
When a stream contains a single program, there's no point in doing a
PID -> program lookup. Normally the one and only program isn't disabled,
so no packets should be discarded.

cabb168169 mpegts: Remove one memcpy per packet 
This was being performed to ensure that a complete packet was held in
contiguous memory, prior to parsing the packet. However, the source buffer
is typically large enough that the packet was already contiguous, so it is
beneficial to return the packet by reference in most cases.

f824535a4a vdpau: deprecate bitstream buffers within the hardware context 
The bitstream buffers are now private and freed by libavcodec. For
backward compatibility, the hold bitstream buffer pointer is left NULL
(applications were supposed to av_freep() it).
