Stereo downmixer supports generic configurations. Fix 7.1 downmix
Added a generic downmixer to stereo function to handle the
multichannel configurations not supported by the dedicated
downmix functions.
It first verifies the mask is supported, and then derives
channel indices for the downmix.
Added support for forcing the generic downmixer to be always
used instead of the format-specific functions (define
DOWNMIX_ALWAYS_USE_GENERIC_DOWNMIXER to force it).
Fixed 7.1 downmix function where handling of accumulate vs
overwrite was inversed.

Effect for multichannel PCM downmix to stereo
First pass at implementing an audio effect whose role is to
downmix multichannel PCM buffers to stereo.
The effect is not handling volume changes.
The effect code here handles quad, 4.0, 5.1 and 7.1 input configurations,
to optimize the most commom configurations, and does not yet handle
generic multichanel configurations.
