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).

This structure is no longer declared in a public header,
so using an FF-prefix is more appropriate.
Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
Up until now, codec.h contains both public and private parts
of AVCodec. This exposes the internals of AVCodec to users
and leads them into the temptation of actually using them
and forces us to forward-declare structures and types that
users can't use at all.
This commit changes this by adding a new structure FFCodec to
codec_internal.h that extends AVCodec, i.e. contains the public
AVCodec as first member; the private fields of AVCodec are moved
to this structure, leaving codec.h clean.

Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault.
This reduces the amount of files that have to include internal.h
(which comes with quite a lot of indirect inclusions), as e.g.
most encoders don't need it. It is furthemore in preparation
for moving the private part of AVCodec out of the public codec.h.
