avutil/channel_layout: rename 7.1(top) channel layout to 5.1.2
...
This layout maps to ITU-R BS.2051-3 "Sound System C" and ITU-R BS.1196-8 "Channel
Configuration 14", and it being the first layout with top layer channels, it's
best to use a different scheme to properly convey the presence and amount of said
channels.
The new name will also be a better fit for the additions in the following commits.

lavu,lavfi,ffmpeg: Remove experimental OpenCL API
...
This was added in early 2013 and abandoned several months later; as far as
I can tell, there are no external users. Future OpenCL use will be via
hwcontext, which requires neither special OpenCL-only API nor global state
in libavutil.
All internal users are also deleted - this is just the unsharp filter
(replaced by unsharp_opencl, which is more flexible) and the deshake filter
(no replacement).

avutil/channel_layout: add av_get_extended_channel_layout
...
Return a channel layout and the number of channels based on the specified name.
This function is similar to av_get_channel_layout(), but can also parse unknown
channel layout specifications.
Unknown channel layout specifications are a decimal number and a capital 'C'
suffix, in order to not break compatibility with the lowercase 'c' suffix,
which is used for a guessed channel layout with the specified number of
channels.
