Just pass through the bitstream as is. This is the same as what is done
for HEVC already.

Deprecate the current bitstream filtering API.

the pps offset is used to locate pps in the spspps_buf; however, the
current calc method is wrong because it is the offset of the original
avctx->extradata;
when there is only one sps in the avcc; the value is correct by
coincidence, however, it will fail in avcc with multi sps

When only SPS or PPS is present in the stream, copy the missing one from
AVCC before insertion to the output stream.

In order not to break a sequence like "SPS IDR SPS IDR", the boolean
telling that the SPS/PPS has been seen should always be set.

If there are consecutive IDR pictures, then SPS/PPS should be prepended
to all of them, not only the first one.

Should an AVC-1 in MP4 stream not contain SPS or PPS NAL units,
this BSF is then unable to allocate an output buffer for the
modified stream. Warn that the resulting stream may be unplayable.

Fix roundup issue #2386.
