ffc1208266 lavf/prompeg: prompeg_write() must report data all was written 
Previously, prompeg_write() would only report to caller that bytes we
written when a FEC packet was actually created.  Not all RTP packets are
expected to generate a FEC packet however, so this behavior was causing
avio to retry writing the RTP packet, eventually forcing the FEC state
machine to send a FEC packet erroneously (and so breaking out of the
retry loop).

This was resulting in incorrect FEC data being generated, and far too
many FEC packets to be sent (~100% FEC overhead).

fix #7863

2658680df4 avutil/internal: remove FF_ALLOCx{_ARRAY}_OR_GOTO macros 
These functions have a terrible design, let us fix them before extending
them.
First design mistake: no error code. A helper function for testing
memory allocation failure where AVERROR(ENOMEM) does not appear is
absurd.

Second design mistake: printing a message. Return the error code, let
the caller print the error message.

Third design mistake: hard-coded use of goto.
