mpeg4videodec: silence ubsan warning
...
s->ac_val[0][0] is of type 'int16_t [16]', but points into a larger buffer.
Here it is used as base pointer to find the correct position in the
larger buffer by adding 's->block_index[n] * 16' and thus as 'int16_t *'.
This fixes clang's ubsan runtime error: index out of bounds for type
'int16_t [16]'
Fixes: test_case.mp4

lavc: add profiles to AVCodecDescriptor

The profiles are a property of the codec, so it makes sense to export
them through AVCodecDescriptors, not just the codec implementations.

avcodec: use HAVE_THREADS header guards to silence -Wunused-function
...
When compiled with --disable-pthreads, e.g
http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7 ,
a bunch of -Wunused-functions are reported due to missing header guards
around threading related functions.
This patch should silence such warnings.

lavc: deprecate the use of AVCodecContext.time_base for decoding
...
When decoding, this field holds the inverse of the framerate that can be
written in the headers for some codecs. Using a field called 'time_base'
for this is very misleading, as there are no timestamps associated with
it. Furthermore, this field is used for a very different purpose during
encoding.
Add a new field, called 'framerate', to replace the use of time_base for
decoding.
