Allow the audio device to be opened only while it's actually used.
This is necessary for uaudio devices, for instance to start aucat
before the device is plugged. Or to unplug a device whithout
having to restart aucat when another device is plugged. This is
controlled with the new -a option.
Allow multiple audio devices to be used concurently, i.e.
multiple ``-f devname'' options to be used; -f options must follow
per-device options, which is what we do for other options.
