Move the keep_dac_busy in to a configuration setting. Always start the keep_dac_busy thread and check if the keep_dac_busy is set. Don't dither is ignore volume control is set.

Fix dither, add dither to silences during lead-in, interpolatied frames and keeping out of standby, only if the output device doesn't use a mixer. Check configuration at initialisation.
