flags parameter to all xxstart routines so that the correct information can
be passed down into the device specific routines. This is needed to ensure
that ccb/scb allocation routines don't hang.

function calls. Broken tracking of open partitions gets fixed as a side
effect. Races in sdopen() and sdioctl() become more numerous than before.
Close the device in sdsize(). Media removal could not have worked right
when unused swap devices were held open. There may now be a problem
with used swap devices not being held open.
Fix ancient operator precedence bug in sddump(). It may have been
possible to attempt dumping to unloaded media.
Remove NetBSD ifdefs. We're too different now, and the NetBSD driver was
already too different for them to be relevant.
Remove support for soft write protection. There are no ioctls to set it,
and this driver never set it either. It was used in the wd driver to
disable writing to unlabelled disk, but we want to support writing to
foreign partitions on unlabeled disks.
Clean up some formatting and restore some old-style function headers.
sd.c: Julian's removal of subdriver requests
st.c, scsi_tape.h: Julian's suport of compressed tape drives
Note: compressed tape drives are still not working fully.
scsiconf.h, scsi_base.c, scsi_driver.c: address problems in probes
and error console logs
Fix it so that calls to extend_get won't dereference 0 when "swap
on sd.." calls sdsize() on systems with no SCSI devices.
This probably really fixes Poul's "boot with no SCSI" problem.
tape drive. I traced it to sys/scsi/scsi_base.c where some code were added
to print the return values of the sense command. My tape drive returned a
extended flags value of 0x20, so the key that is the lower 4 bits, is 0.
The code uses "key-1" to index into a table and then the kernel go to never-
never land.
Here is a fix for this. Will somebody please apply it?

Reenabled "SCIOCOMAND" ioctl.
Restructured so low level drivers can easily request retries.
Added preliminary fixed SCSI devices (should be revisited before 2.1)
Added "ssc" device that can have its' (HBA, ID, LUN) set via ioctl.
Change the sc_link structure from 8 targets with 8 lun's to
16 targets with 8 lun's. Wide scsi and the ncr 825 does support 16 targets.
scsiconf.c:
move the addition of the trailing NUL's out of a then clause, they are also
needed in the else clause for an unknown device.
scsi adapter. Let it work on every adapter. Someone want to rewrite
this to be coupled with the adapter specification in the config file,
so that you can say which adapters need it ?
device announcement; assume a sector size of 512 instead (likely to be
right at all).
This case happens when booting with a removable disk device attached
(e.g. an MOD), but no medium inserted.
