Private API meant to be used by plugins whose backends expect frame
rate values represented by a ratio.
The function implementation was moved from the AVFoundation plugin
to the QtMultimedia library.

AVFoundation on iOS lacks the ability to use AVCaptureVideoDataOutput and
AVCaptureMovieFileOutput simultaneously. Right now viewfinder stops working
as soon as we add movie file output. The only workaround
we have now is to write video/audio 'maually' - creating asset writer
and feeding it with audio/video samples.

Excluding video range (iOS) is not the right way to avoid "duplicates" - with
other devices there can be also duplicates (formats with the same resolutions),
but completely different pixel formats. Since we do not know what they will be in advance,
we take the media subtype from the initial preset for a capture device and use it
as a filter. Update viewfinder and image encoder settings controls.

Move configuration lock class into avfutility.h + add several standalone functions
to work with AVCaptureDeviceFormat/AVCaptureDevice etc. - utility functions that are not
specific to any class.
