 This patch generalises the upmix / AC-3 (re)encode functionality. Main
 thing is that it makes upmix and encode to DD5.1 work.

 Also:

 * Fix resampler clipping [[BR]]
 * Turn on resampler where sr != 48k ![1] [[BR]]
 * Fix passthru where main dev:subdev == passthru dev:subdev ![2][[BR]]
 * Add keybind (Ctrl+U) / OSD menu option to toggle upmixing [[BR]]
 * Preserve timestretch across stream changes / upmix toggles [[BR]]
 * Small change to freesurround params [[BR]]

 ![1] Recent versions of ALSA will do this if we don't. The SRC we use is
 much better quality.

 ![2] Like my nvidia CK804

 Patches against fixes and trunk attached. Tested on fixes only.
