a1a707f728 Add a new function av_codec_get_tag2().
av_codec_get_tag() may return 0 both in case a codec_tag was
found and if no codec_tag was found.
The new function does not have this ambiguity.

46730e7a0c mux/chunked interleaver: better align duration chunks.
This code causes the chunking to tend toward more optimal
alignment between streams.
The first chunks can still be less optimal aligned

0942aa4637 lafv/matroska: add A_OPUS/EXPERIMENTAL codec name.
The exact packing of Opus inside Matroska is not finalized.
Use A_OPUS/EXPERIMENTAL as codec name, like mkvtoolnix.
The A_OPUS name stays to let ffmpeg open files it has produced
until now, but newly produced file use the EXPERIMENTAL version.
Once the spec is stabilized it will be possible to consider
options to ensure compatibility with these files.

2c85d7c015 h264: add 3 pixels below for subpixel filter wait position.
If the motion vector is at a subpixel position, we need 3 pixels below
the motion vector's wholepel position available, not 2, since the MC
filter is a sixtap filter for the hpel position, and then a bilin filter
for the qpel position.

This patch fixes highly irreproducible (0.1%) fate failures in frame 2
and 4 of h264-conformance-cama2_vtc_b (e.g. first P-frame, first field,
last line of MB x=40,y=2 and second field and last lines of MBs x=39-40,
y=3). These used pre-loopfilter instead of post-loopfilter data because
the await_progress() waited for one line too little in that field, and
the motion vector of these particular MBs happened to align exactly to a
position where that demonstrates the bug.
