1ec28a66f2 rtpdec: fix issue with conversion from unsigned to signed 
When receiving an RTCP packet, the difference between the last RTCP
timestamp and the base timestamp may be negative. As these timestamps
are of the uint32_t type, the result becomes a large integer. Cast
the difference to int32_t to avoid this issue.

The result of this issue is very large start times for RTSP
streams, and difficulty to restart correctly after a pause.

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)
