db1e39a4e8 Allow partial build with selected components 
Add --enable-* and --with-pcm-plugins configure options for partial builds.

User can choose the core components (pcm, mixer, rawmidi, hwdep, seq, instr)
via --enable-xxx or --disable-xxx option.  As default, all components are
enabled.

The PCM plugins to build can be selected via --with-pcm-plugins option.
For example, to build only rate and linear plugin, pass
  --with-pcm-plugins=rate,linear
Passing "all" will select all plugins (it's the default value).

The plug plugin will select linear and copy plugins automatically.
The other auto conversions of plug plugin are enabled only when the
corresponding plugin is selected.

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.
