current_picture was not writable here because a reference existed in
at least avctx->coded_frame, and potentially elsewhere if the caller
created new ones from it.

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 1f4cf92cfb.
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);

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

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.
