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).

It is a constant known at codec init, so set it in
ff_frame_thread_init(). Also, only set it for video, since the meaning
of this field is not well-defined for audio with frame threading.

Fixes availability of delay in callbacks invoked from the per-thread
contexts after 1f4cf92c.

This causes regressions in end to end timestamps with mp3s and ffmpeg.
The revert is to avoid this regression in the 4.3 release

See: [FFmpeg-devel] [PATCH] Don't adjust start time for MP3 files; packets are not adjusted.

This reverts commit 460132c9.

This makes got_output consistent with the code in slice_end() which sets the output

 if (s->pict_type == AV_PICTURE_TYPE_B || s->low_delay) {

They are no longer necessary there and have nothing to do with parameter
sets, so do not belong in hevc_ps.h.

This effectively reverts 4aaace8b.

It is only used to store a few local variables within one function,
which is better accomplished by just declaring them on stack explicitly.

Inside a function, the second ; in a double ;; is a null statement, but
outside of functions a double ;; is simply invalid C that compilers
happen to accept. v4l2_m2m_enc.c contained several ;; as a result of
macro-expansion. So change the underlying macro so that it doesn't
happen any longer.

This fixes warnings when compiling with -pedantic: "ISO C does not allow
extra ‘;’ outside of a function".
