Morphing was introduced in 0d6e5a17 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.

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

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 28f9ab70 (and the output visually looks
correct).

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.

This patch can be controversial, by assuming floats are IEEE-754 and
particular behaviour of the FPU will get in the way.
