webrtc uses a int32_t like the existing code in ilbcdec

The specification allows 2^32-1 to be encoded as any number of zeroes
greater than 31, followed by a one. This previously failed because the
trace code would overflow the array containing the string representation
of the bits if there were more than 63 zeroes. Fix that by splitting the
trace output into batches, and at the same time move it out of the default
path.
(While this seems likely to be a specification error, libaom does support
it so we probably should as well.)

Silences a warning with clang on arm:
libavcodec/opus_rc.c:170:17: warning: passing 'const uint8_t *' (aka 'const unsigned char *') to parameter of type 'void *' discards qualifiers
delta_frame_id_minus1 is not a single value in the bitstream, and can
store values up to 17 bits wide.
Fixes parsing files with frame ids.

1. Old logic meaned: everywhere, except Windows, ffmpeg has to use HW
acceleration, but on Windows ffmpeg has to use (unavailable) software
HEVC by default
2. Software HEVC is available only if you provide corresponding
software MediaSDK library, which isn't provided with ffmpeg. More
information could be found in
https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/samples/readme-encode_linux.pdf
3. HW HEVC decoding/encoding are available on Windows in the driver by default
Note: Default case should be the most common case but this change still has potential risk
on windows if HW path is not supported(or doesn't work as expection).
(See the historical disscution: https://lists.libav.org/pipermail/libav-devel/2016-November/080419.html).
In such case, two options suggested:
1. Use the option "-load_plugin hevc_sw" to switch SW path manually.
2. Or report bug to Intel windows driver if your GPU can support HEVC HW codec.
(HEVC decoding is supported since Braswell, and encoding supported since Skylake)
Patch started by Landgraph. Add similar change for hevc decoder and bump a new version.

Fixes#7410.
The value of sub-pixel precision for me/mc can change during an Intra frame. In multi-threaded decoding this change is not propagated to other frame threads causing decoding artifacts. This patch initializes the sub-pixel precision parameter from previous thread, which fixes the issue.

Now "-c copy" works.
Update FATE files.
Demuxer only split file into packets, no data is trimmed.
Encoder & muxer currently expect completely another format
where muxer writes stuff like disposal method which should
be really encoder job.
With this patch muxer only modifies delay between two packets.
Codec copy need to have same behavior between demuxer and
muxer to work correctly.
Fixes#6640.
The issue is that the afq still has samples as on init it counts
the overlap used as a delay to adjust the PTS it generates, hence
we can't rely on it right after init.
So just check to see if any frames have been encoded. frame_number
can't be anything but 0 right after init and can only be set by lavc.
