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
