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.

nvmf: Auto-reconnect periodically after a disconnect

Use a timer in the nvmf(4) driver to periodically trigger a devctl
"RECONNECT" notification. A trigger in the /etc/devd/nvmf.conf file
invokes "nvmecontrol reconnect nvmeX" upon each notification. This
differs from iSCSI which uses a dedicated daemon (iscsid(8)) to wait
inside a custom ioctl for an iSCSI initiator event to occur, but I
think this design might be simpler.

Similar to nvme-cli, the interval between reconnection attempts is
specified in seconds by the --reconnect-delay argument to the connect
and reconnect commands. Note that nvme-cli uses -c for short letter
of this command, but that was already taken so nvmecontrol uses -r.
The default is 10 seconds to match Linux.

In addition, a second timeout can be used to force a full detach of a
disconnected the nvmeX device after the controller loss timeout
expires. The timeout for this is specified in seconds by the
--ctrl-loss-tmo/-l options (identical to nvme-cli). The default is
600 seconds.

Either of these timers can be disabled by setting the timer to 0. In
that case, the associated action (devctl notifications or full detach)
will not occur after a disconnect.

Note that this adds a dedicated taskqueue for nvmf tasks instead of
using taskqueue_thread as the controller loss task could deadlock
waiting for the completion of other tasks queued to taskqueue_thread.
(Specifically, tearing down the CAM SIM can trigger
destroy_dev_sched_cb() and waits for the callback to run, but the
callback is scheduled to run in a task on taskqueue_thread. Possibly,
destroy_dev_sched should be using a dedicated taskqueue.)

devd.conf.5: Expand the width of various columns

Using upper case for column width templates avoids overfull columns
when using groff to generate a postscript version of the manpage but
doesn't affect the terminal version.

Use a wider default column (8 characters) for the "Type" column and
use wider widths for tables with longer event types.

In the terminal, man(1) forces a line break after overfull column
items, but in the postscript and HTML versions the column just
overflows into the adjacent column without any separation.
