Original change's description:
> Detangle cyclical references in CC metrics
>
> This refactor performs the following:
> * Remove Add/Rem tracker calls from FSTC to CFRC
>   and move all logic to FSTC
> * Have CFRC delegate active tracker calls to FSTC
> * Make DFC a FSTC member rather than delegating
>   through CFRC
> * Remove FrameSorter from DFC, move to CFRC globals
>   and register both DFC and FSTC as observers of
>   FrameSorter. This replaces Callback pattern with
>   the observer pattern.
> * Rename former callbacks to "AddSortedFrame" so
>   they can use the same observer interface.
