Commit message partly taken from carl

fixes a compilation
error in mlpdsp_init.c with -fstack-check and some gcc compilers (I
reproduced the issue with gcc 4.7.3) by simplifying the code.

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.

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

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

This improves the cleanup, dependency generation and DBG command issuing.
