Add a "device number" component in sndio(7) device names, allowing a

single aucat instance to handle all audio and MIDI services. Since
this partially breaks compatibility, this is a opportunitiy to fix few
other design mistakes (eg ':' being used by inet6, type name vs api
name confusion, etc..). This leads to the following names:

        type[@hostname][,unit]/devnum[.option]

The device number is the minor device number for direct hardware
access (ie the 'N' in /dev/audioN). For aucat, this is the occurence
number of the -f (or -M) option.

There's a compatibility hook to keep old names working if only one
aucat server is running.
