srtp: Include rtpdec.h for RTP_MAX_PACKET_LENGTH
rtpdec: Increase max rtp packet size to 8192
lavf: Use RTP_MAX_PACKET_LENGTH instead of 1500
h264pred: Add a few missing const declarations for ff_cropTbl derived pointers
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The pointers that get assigned ff_cropTbl were made const in
9e0f14f1, but other variables that transitively are assigned
based on these variables were missed.

Morphing was introduced in 0d6e5a171 and forced cos/sin computations
with some mult all the time. This commit makes sure these are computed
only when morphing is enabled.
WAV chunks must be even aligned. This patch skip the extra padding byte
if chunk size is odd.
Fixes ticket #2417.

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.

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

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

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

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.

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.
This patch can be controversial, by assuming floats are IEEE-754 and
particular behaviour of the FPU will get in the way.
Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference).
