QSV: base the B-pyramid check on the presence of B-references, rather than the initial delay.

This is potentially more accurate.

QSV: add an option to select the preferred implementation at runtime.

This is intended for developers only; having to rebuild just to compare software to hardware is annoying as hell.

Revert previous commit, sorry.

I forgot about capabilities, we can't just swap the preferred implementation like that.
