snd_hda: Implement automatic redirection between associations

For audio to be redirected to the headphones/headset after plugging the
jack, or back to the speaker/internal mic when unplugging it, the
speaker and headphone pins need to be part of the same association
(i.e., the same PCM device). This patch makes it possible to redirect
audio even between different associations, which can reduce the need for
manual pin patching.

The idea is that we issue a devctl_notify() from within the jack
detection callback whenever a jack is (un-)plugged to redirect audio to
the appropriate device. Then the snd.conf devd script is responsible for
using virtual_oss to change the playback/recording device to whatever
snd_hda(4) selected. The reason for requiring virtual_oss is that it has
hot-swapping support, which is necessary for jack redirection.
