Look for the generic "USR" labels instead of "?" to skip channels with no
known names, and actually print the decomposition of standard channel layouts.

This patch is analogous to 20f972701806be20a77f808db332d9489343bb78:
It hides the internal part of AVBitStreamFilter by adding a new
internal structure FFBitStreamFilter (declared in bsf_internal.h)
that has an AVBitStreamFilter as its first member; the internal
part of AVBitStreamFilter is moved to this new structure.

All FF_QSCALE_TYPE values used by libavfilter originate
from libavfilter (namely from ff_qp_table_extract());
no value is exchanged between libavcodec and libavutil.
The values that are exchanged (and used in libavfilter)
are of type enum AVVideoEncParamsType.
Therefore this patch stops using said FF_QSCALE_TYPE_*
in libavfilter and uses enum AVVideoEncParamsType
directly.

Especially useful when debugging subtitle output, but also shows
if values are set or not for demux and encoding.

Otherwise get_pixel_format() will not be called when parsing a subsequent Sequence
Header in non hwaccel enabled scenarios, allowing frame parsing when it shouldn't.
This prevents the scenario seqhdr -> frame_hdr/redundant_frame_hdr -> seqhdr ->
redundant_frame_hdr from having the latter redundant frame header parsed as if it
was a frame header by the decoder because the former was discarded.
Since CBS did not discard it, the latter redundant frame header is output with a
zeroed AV1RawFrameHeader struct, which can have undesired results, like division
by zero with fields normally guaranteed to be anything else.

Due to a quirk of the ASS format some tags depend on the exact storage
resolution of the video, so tell libass via ass_set_storage_size.

It allocates a dummy sws/swr context and tries setting options on it,
apparently to check if they are valid. This is redundant, since the
options will be checked if/when they are later applied on a context that
is actually used for conversion.
It tries to process any unhandled options as AVOptions. Handle this
directly in cmdutils.c, without resorting to a confusing fake option
definition (which is currently visible to the users in -help output).
Fix below error message when timecode packet is written.
"Application provided duration: -9223372036854775808 / timestamp: -9223372036854775808 is out of range for mov/mp4 format"
try to reproduce by:
ffmpeg -y -f lavfi -i color -metadata "timecode=00:00:00:00" -t 1 test.mov
Note although error message is printed, the timecode packet will be written anyway. So
the patch 2/2 will try to change the log level to warning.

Deprecate the channels option, and ensure ch_layout has priority if set over
channels, until the latter is gone.

It is a more fitting place for them.
Also move the definition of ff_log2_run to mathtables.c.

bitstream.c is currently the disjoint union of three parts:
The first part is ff_log2_run, the second part are some auxiliary
functions for the PutBits-API; and the third part is the code
for creating VLCs. This commit moves the latter into a file of its own.
This has the advantage of making one of the hacks in tableprint_vlc.h
redundant as vlc.c does not include config.h (whereas the PutBits-API
part does).
