Since side data is being split and merged at a latter point during
av_interleaved_write_frame() and av_write_frame() calls, maybe we
could just move the relevant code before the autobsf kicks in.

See attached patch. FATE passes and the sample from ticket 5927
works with autobsf, same as with your patch.
It doesn't change ffmpeg.c manual bsf's behavior, though. For that
your commit from yesterday is still needed.
