The new API is more extensible and allows for custom layouts.
More accurate information is exported, eg for decoders that do not
set a channel layout, lavc will not make one up for them.
Deprecate the old API working with just uint64_t bitmasks.

Changes since last version:
*Both av_channel_layout_describe() and
av_channel_layout_from_string() now
support a "2 channels (FL+LFE)" syntax, to signal native (usually
non-standard) or custom order layouts.
*a single decimal value is now interpreted as a mask by
av_channel_layout_from_string(), same as a single hexadecimal
value.
*De-duplicated code by simplifying
av_channel_layout_channel_from_string().
The entire set can still be found in

didnt bisect but
this
./ffmpeg -i ~/tickets/3542/out.mov -channel_layout stereo -acodec
pcm_s16be file.mov
fails after the patchset but not before

Should be fixed.
Heres another which broke around the channel change
./ffmpeg -i tickets//2064/mus_sympathy_for_the_devil_l.wav file.wav
"tickets//2064/mus_sympathy_for_the_devil_l.wav: Function not
implemented"
file seems here:
https://www.djxmmx.net/ffmpeg/2064/
What was this file read as before the set? Ticket 2064 mentions a file
with a wav extension that's an "unknown container", and then the ticket
was closed as fixed without referencing a commit.
Nevermind, it's "Black ops audio" container. I see what's wrong.
Will fix in a bit.
