7099deadda 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
driver.

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.

phk
38290a3baa 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.

84a309987c 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.

2a47b08091 Make bsd_disklabel_le_enc calculate the checksum and fill it in. 
(If there is a legitimate need to correctly encode and pack a
disklabel with an invalid checksum custom tools can be built for
that.)

Make bsd_disklabel_le_dec() validate the magics, number of partitions
(against a new parameter) and the checksum.

Vastly simplify the logic of the GEOM::BSD class implementation:

Let g_bsd_modify() always take a byte-stream label.

This simplifies all users, except the ioctl's which now have to
convert to a byte-stream first.  Their loss.

g_bsd_modify() is called with topology held now, and it returns
with it held.

Always update the md5sum in g_bsd_modify(), otherwise the check
is no use after the first modification of the label.  Make the
MD5 over the bytestream version of the label.

Move the rawoffset hack to g_bsd_modify() and remove all the
inram/ondisk conversions.

Don't configure hotspots in g_bsd_modify(), do it in taste instead,
we do not support moving the label to a different location on the
fly anyway.

This passes all current regression tests.

a43e2a0d8e Fix an obscure fencepost error in GBDE's sector mapping code: 
For certain combinations of sectorsize, mediasize and random numbers
(used to define the mapping), a multisector read or write would ignore
some subset of the sectors past the first sector in the request because
those sectors would be mapped past the end of the parent device, and
normal "end of media" truncation would zap that part of the request.

Rev 1.19+1.20 of g_bde_work.c added the check which should have alerted
me to this happening.  This commit maps the request correctly and
adds KASSERTS to make sure things stay inside the parent device.

This does not change the on-disk layout of GBDE, there is no need to
backup/restore.

46e72efe59 When a bio comes back from below with a zero error code, check that 
it wrote the full length.  The only case where this should be able
to happen is if we try to read/write past the end and the request
is truncated.  We obviously should never try to do that, so this
code should never activate.

82e4f296ff If on a BIO_READ request, we failed to allocate the bio for reading 
our key-sector, we would end up returning the read without an error,
despite the fact that the data was not correctly decrypted.

This would result in data corruption on read, but intact data still
on the media.

017246b9b8 Fix a problem and slightly improve the ENOMEM handling: 
Give up the entire bio as soon as we detect a problem.

When we detect a problem, give up the bio by contributing the
remainder with ENOMEM, rather than kicking the bio back right
away.

If we failed on a non-first iteration we previously could end up
modifying fields in the bio after we delivered it.  This could
account for memory corruption (none directly reported) on machines
with GBDE.
