Problem: if FF_API_PACKING, we break ABI with libav, since the "format" and
subsequent field are shifted; if not FF_API_PACKING, we break ABI with
previous versions.

Either way is bad, but I am not sure that keeping the situation until the
next major bump is the best solution.

(I was trying to reconcile buffersrc.c and src_buffer.c, and for that,
trying to get avconv to work with dynamic libraries from ffmpeg. This issue
causes a failure.)
