Ilya Nikolaevskiy 8102a1a8ea Revert "Partial frame capture API part 1"
This reverts commit 8a21e1c9c95c9b9b570c84bdfeda0315ede9dc29.

Reason for revert: breaks buildbots

Original change's description:
> Partial frame capture API part 1
> 
> Define new optional struct in VideoFrame to signal that the frame is a
> changed part of a whole picture and add a flag to signal that partial
> update may be issued by the VideoFrame source.
> 
> Also, fix too strict assumptions in FrameBuffers PasteFrom methods.
> Also, add ability to set a new buffer in video frame.
>
