8b25681eb5 Replaced bogus macros for dummy devswitch entries by functions.
These functions went away:

	enosys (hasn't been used for some time)
	enxio
	enodev
	enoioctl (was used only once, actually for a vop)

if_tun.c:
Continued cleaning up...

conf.h:
Probably fixed the type of d_reset_t.  It is hard to tell the correct
type because there are no non-dummy device reset functions.

Removed last vestige of ambiguous sleep message strings.

4fda91c705 Moved prototypes for devswitch functions from conf.c and driver sources
to <machine/conf.h>.  conf.h was mechanically generated by
`grep ^d_ conf.c >conf.h'.  This accounts for part of its ugliness.  The
prototypes should be moved back to the driver sources when the functions
are staticalized.

dd1642c2c4 Fixed the type of sscstrategy() (return void).
Removed sscdump() (it was never used).
Removed sscpsize() (it was never used, and returned a bogus value (ENXIO = 6
means a size of 6)).

b372e37cdf The "od" driver. While the name is suggesting the use for
magneto-optical devices, it's scope can (and should) be widened to
cover all removable type 0 (direct) devices as well, since this class
of devices is sharing the same principles.  Things like suport for
media eject etc. will be supported later.  (Shunsuke is also working
on the problems arising out of the use of media with physical block
size != 512 bytes (which is not uncommon for MODs).

f60e6466c4 Include the "od" driver. (Oops, forgot to cvs add the driver file
itself.  Will do this after this commit.)

Make scsiconf more flexible about recognizing ``foreign'' devices.
This part needs to be rewritten some day to allow for matches whithou
strict version number checks, but either Julian as Peter seem to be
too busy right now, so i'm finally commiting the version that's
working for me stable now for several months, as an interim
workaround.

b629f8ebbe Some bug fixes for the worm driver:
o  don't use polled mode after the device probe phase
o  don't biodone() a NULL buffer pointer
o  increase the timeout for scsi_read_capacity(); WORMs are slooow
o  make WORMMs known to scsiconf at all

This brings the driver in a state where it at least doesn't
immediately panic, nor hangs the controller any more.  Unfortunately,
at least the YAMAHA CDR100 i've been testing with answered my write
attempts with an "Incorrect command sequence" response.  Perhaps other
CD burners might work however.

07b1c6b3c9 Remove hard coded assumption that SCSI busses have 7 targets.
This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct.  Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal.  For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).

Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*.  This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).

73145c38cc Change memcmp() to bcmp(). memcmp() isn't declared or implemented
for the kernel, but gcc provides an inline version of it if the
kernel is compiled with -O.

The inline memcmp() is OK for small compares and is better than
the dumb kernel bcmp() in all cases, but it has been hiding the
library memcmp() which is 4 times faster for large compares.

31acd246c0 Allow the specification of the controller bus when wiring down scsi buses.
This is performed by using a line similar to:

controller scbus0 at ahc0 bus 1

to wire scbus0 to the second bus on an adaptec 2742T controller.

ffc2aaf2d8 Do not set SCSI_NOSLEEP on every tape command (the exception being during
probes).  Apart from there being no reason to set SCSI_NOSLEEP on every
tape command, this prevents controller drivers from sleeping when resources
are fully utilized causing unecessary "Oops not queued" errors.  This is
only noticed for controllers that can run out of resources like the
27/2842 adaptec controllers.  Before this fix, it is almost impossible to
perform extended tape operations if more than one scsi disk is on the
bus with the tape drive with these controllers.  This does not address a
similar problem that could occur if devices are probed while other targets
are active since SCSI_NOSLEEP will still be set in that case.

a1c6084710 Support disk slices. This involves mainly replacing inline code with
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.
