henry 1fd3c733d8 More HRTF enhancements ...

- a passive locking mechanism to enable the matrix to switch between active
and passive mode, which enhances the stereo image.

- a center front cancellation algorithm that damps the cross-talk if the
sound is coming predominantly from center (e.g. if there is dialogue).

These two new features should enhance the quality of surround downmix
noticeably.

Also a correction to the active gain control is included. The previous
implementation of Lt + Rt/Lt - Rt AGC should be fine in most cases, but the
calculation was inconsistent (gain unitarity is not guaranteed to be
preserved).
