This allows fuzzing decoders with the same codec_id
We also avoid register all to allow the linker to prune unused sections and symbols

h264dec: make sure to only end a field if it has been started
This commit is a noop. Our h264 slicing handling is different and does
not seem to be affected by the issue.

Because write_packet() fakely writes packets to muxer by queueing
them when muxer hasn't been initialized, it should also increment
frame_number fakely.
This is required because code in do_streamcopy() rely on
frame_number.
Should fix Ticket6227

So, all frames and errors are correctly reported in order.
Also limit the numbers of error during draining to prevent infinite loop.
This fix fate failure with THREADS>=4:
make fate-h264-attachment-631 THREADS=4
This also reverts a755b725ec.

2017-04-29 13:21:45 michaelni ubitux, the libav code refered to is wrong for us and i doubt the problem it fixes applies to us.
2017-04-29 13:24:29 @ubitux michaelni: ok, for both commits?

find_fps attempts to infer framerate from AVCodec's timebase. When this
results in a frame rate that isn't explicitly marked as supported in
av_timecode_check_frame_rate, find_fps returns the AVStream's
avg_frame_rate, which, per avformat.h, _may_ be set (or not).
mov_get_mpeg2_xdcam_codec_tag, mov_get_h264_codec_tag and
find_compressor attempt to call av_q2d on the return value of find_fps,
which in the above case, may result in division by zero and therefore,
an undefined frame rate when NaN is converted to int.
