Currently, a part of the loop has to be handled in plain C, because of DSP
function requirements of having batches of 16 elements to process.
Instead, pad the buffer with 0 where the DSP functions are overreading.

When a client behind a NAT issues a pause command, and stay paused for a
long time, the router may stop the RTP/RTCP port redirection. Resend the
hole punching packets after each PLAY command to cause the router to
restart the port redirection in that case.

The comments/header of the file are taken from qemu, they provide some
basic documentation
The code from the examples
Ive no means to test this except uploading to coverity for FFmpeg, so each
commit should stay simple, making it easy to revert.
Also please help making this a useful and effective file by contributing
changes/code to it and reviewing contributions.
I am happy to upload changes but i cannot really maintain this (alone) as
i cannot test changes.

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.
