that may run without interrupts, don't forget to add scsi_autoconf
to the flags and POLL for the result rather than wait for an interrupt that
will never come. Fixes Dale's Iomega Jazz drive on the ahc here, and no
doubt many other device combinations.

tape drives it is nice not to crash if one is detached. Basically use
a consistant mechanism modelled on sd to lookup devices and do the
device reference increments and decrements. Problem reported (PR#5811)
and fix tested by Jozef Hatala. Still some corner cases Jozef is
looking for but we'll fix those as discovered.

should fix a number of 'drive offline' situations where the device claims
it has no media loaded until the lock in occurs. Like a Blackberry Pearl
Todd Fries found and probably other USB devices. Move the lock in during
device open to before the test unit ready to eliminate similar spurious
rejections of the device.
Feedback from marco@, tests by todd@ and miod@.

geometry. But 63 * 255 > 2880 and the cylinder count becomes 0. So
if we end up with a valid disksize but 0 cylinders, set heads =
cylinders = 1 and sectors-per-track = disksize.

device before issuing scsi commands to it, but it was never implemented,
never used, and no hba actually filled them in. i came along and added
another two function pointers for the same thing.
this cleans up the extra pointers.

"adapter_softc" is simply a way for the adapter to determine what scsibus
it is now dealing with, not a pointer back to the adapters device struct.

sent to the adapter instead of the 10 bytes the scsi_sychronize_cache
command actually occupies. This freaked out the ahc on jsing@'s SGI
and probably others.
Found, isolated, fix tested, and ok jsing@

called from the last sdclose() on a device will now reset SDF_DIRTY
after submitting the SYNCHRONIZE CACHE command. sddone() need not
worry about SDF_DIRTY since it was never called for the SYNCHRONIZE
CACHE command anyway.
This eliminates a spurious SYNCHRONIZE CACHE command being issued for
every sd device from sd_shutdown().

and a file is written onto the stick. Without these fixes the
machine panics or hangs.
The usb fix calls the callback when the stick is pulled out to free
the associated buffers. Otherwise we have busy buffers for ever
and the automatic unmount will panic.
The change in the scsi layer prevents passing down further dirty
buffers to usb after the stick has been deactivated.
In vfs the automatic unmount has moved from the function vgonel()
to vop_generic_revoke(). Both are called when the sd device's vnode
is removed. In vgonel() the VXLOCK is already held which can cause
a deadlock. So call dounmount() earlier.
