h264: initialize H264Context.avctx in init_thread_copy

This prevents using a wrong (first thread's) AVCodecContext if decoding
a frame in the first pass over all threads fails.

h264: only ref cur_pic in update_thread_context if it is initialized

It may be empty if the previous thread's decode call did not contain a
valid frame.

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%

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)

lavf/ffmenc: do not fail on missing codec

ffm encoder fails when codec is not found.
It may happen when stream is being copied.
