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

in slice_end()
 if (s->pict_type == AV_PICTURE_TYPE_B || s->low_delay) {
     int ret = av_frame_ref(pict, s->current_picture_ptr->f);
     ...
 } else {

This causes indexes into scale_conversion_table to wrap around, alternatively they
could be clipped, the table be enlarged or we can error out. I have not found a document that specifies
what is the correct way to handle this

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".

I have attempted to write a JPEG2000 Parser. Have tested
by generating a file containing 14 frames, as mentioned
by Micheal. Have also tried testing with various packet
sizes by setting -frame_size option. Additionally,
fixed a few formatting issues as pointed out by Micheal.
