swresample/swresample: Rectify invalid function in the documentation
...
The function av_opt_set_channel_layout has been removed since
version 7.0, and the replacement is av_opt_set_chlayout.
The documentation needs to be updated accordingly.

Keep including the full version.h when headers are included externally
...
This avoids unnecessary churn and build breakage for users, by
making sure the whole version.h is included like it has been so far,
while keeping the benefit of not needing to rebuild most files in
the ffmpeg tree on minor/micro bumps.

doc/resampler, swresample/options: use proper capitalization
...
Proper names should be capitalized in all user facing API as far as
possible. The option names themselves have not been changed since:
1. We consistently keep option names in lower case.
2. Changing them would break existing scripts.
3. I suspect that we want to be similar to Sox and its relevant options.
The converse is also true: improper names should not be capitalized
generally.
