The present defaults for the open and close for device drivers which

provide no methods does not make any sense, and is not used by any

It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.
Change the defaults to be nullopen() and nullclose() which simply
does nothing.
Remove explicit initializations to these from the drivers which
already used them.

Simplify the ioctl handling in GEOM.
...
This replaces the current ioctl processing with a direct call path
from geom_dev() where the ioctl arrives (from SPECFS) to any directly
connected GEOM class.
The inverse of the above is no longer supported. This is the
situation were you have one or more intervening GEOM classes, for
instance a BSDlabel on top of a MBR or PC98. If you want to issue
MBR or PC98 specific ioctls, you will need to issue them on a MBR
or PC98 providers.
This paves the way for inviting CD's, FD's and other special cases
inside GEOM.

Add "GEOM_FOX", a class which detects and selects between multiple
...
redundant paths to the same device.
This class reacts to a label in the first sector of the device,
which is created the following way:
# "0123456789abcdef012345..."
# "<----magic-----><-id-...>
echo "GEOM::FOX someid" | dd of=/dev/da0 conv=sync
NB: Since the fact that multiple disk devices are in fact the same
device is not known to GEOM, the geom taste/spoil process cannot
fully catch all corner cases and this module can therefore be
confused if you do the right wrong things.
NB: The disk level drivers need to do the right thing for this to
be useful, and that is not by definition currently the case.
