30f35c1f7a Add softvol PCM plugin 
The softvol PCM plugin is added.  It applies the software volume attenuation,
which may be useful for codecs without volume controls.

Currently, the control is only mono.  The attenuation is applied to all
channels equally.  The control is probed and automatically created
when not exists yet.

messages are not shown in stderr and no assert() as default.  The
behavior can be changed with LIBASOUND_DEBUG environment variable.
