fc2473f826 Translate the source position separately 
This is to handle the case where an app specifies the same values for the
source and listener, and expects centered panning. This fails due to floating-
point errors in the matrix, causing the result to be ever-so-slightly off of 0.

This error would normally be hidden by the position normalization, which will
not lengthen a distance shorter than the reference distance so the panning
would be nearly imperceptible. But that also fails if the reference distance
is set to 0, causing the position to expand to a full unit.

Keep the 4x4 matrix calculations, however. It will still be useful for the
requested listener matrix extension.

35a9ccb41f Revert "Base air absorption on the distance attenuation" 
This reverts commit c7c2f9385f.

Fundamentally wrong. The -6dB rolloff is every doubling of the distance, and
the (scaled) -0.05dB rolloff is supposed to be every additional unit.

0ac9e57d28 Store the requested mono/stereo source count and sends in the device 
Although the properties are set as context attributes, they are queried from
the device. If multiple contexts per device are ever supported, it would not
be straight forward about where to read the values from. This way, the
attributes can be treated as device-specific attributes that are updated when
a new context is created.
