76ce9bd8e2 libavutil: Add ARM av_clip_intp2_arm 
add ARM code for implementing av_clip_intp2 using the ssat instruction

on Cortex-A8, av_clip_intp2_arm() is faster than av_clip_intp2_c() and
the generic av_clip(), about -19%

bf07d813f6 libavutil: Add av_clip_intp2 
there already is a function, av_clip_uintp2() that clips a signed integer
to an unsigned power-of-two range, i.e. 0,2^p-1

this patch adds a function av_clip_intp2() that clips a signed integer
to a signed power-of-two range, i.e. -(2^p),(2^p-1)

the new function can be used as a special case for av_clip(), e.g.
av_clip(x, -8192, 8191) can be rewritten as av_clip_intp2(x, 13)

there are ARM instructions, usat and ssat resp., which map nicely to these
functions (see next patch)

92e3a6fdac avutil: check pixdescs in a different place 
Doing this check in avutil_version() is not appropriate. Also, this code
is by default disabled (--assert-level is by default 0). A FATE run with
defaults will never execute the checks.

Move it to the pixelutils test program. Whatever reason there was in
avutil_version() not to run this test by default, it should be fine in
this test program. This means FATE will run the test by default. (Yes,
pixelutils is not strictly the best place for it either, but it's
better.)

(pixdesc.c also has a small test program, but it's never run by FATE.)
