lavc: fix recoded subtitles end.

Text subtitles packets are not 0-terminated (and if they are,
it is handled by the recoding process since 0 is a valid
Unicode code point). The terminating 0 would overwrite the
last payload octet.

OTOH, packets must be 0-padded.

Fix a problem reported in trac ticket #2431.

x86: sbrdsp: implement SSE qmf_deint_bfly

From 312 to 89/68 (sse/sse2) cycles on Arrandale and Win64.
Sandybridge: 68/47 cycles.

Having a loop counter is a 7 cycle gain.
Unrolling is another 7 cycle gain.
Working in reverse scan is another 6 cycles.

bfin: Don't use the vp3 idct functions if bitexact behaviour is expected

In the non-bitexact mode, vp3 currently decodes to the same
frame crcs as before 28f9ab702 (and the output visually looks
correct).

vp3: Embed idct_permutation array directly in VP3DecoderContext

This makes the vp3 decoder less dependent on dsputil, and will aid
in making it (eventually) dsputil-independent.

x86: qpel: Move fullpel and l2 functions to a separate file

This way, they can be shared between mpeg4qpel and h264qpel without
requiring either one to be compiled unconditionally.

lavc: Make pointers to ff_cropTbl const

There's no point in these pointers not being const.

lavc: Move ff_cropTbl and ff_zigzag_direct from dsputil to mathtables

These are widely used throughout libavcodec, nothing dsputil-specific.

Change ff_cropTbl to a statically initialized table, to avoid
initializing it with a function call.
