cae71ba91d Various changes: 
* Add a dkdevice; move sc_*openpart, sc_label, and sc_cpulabel into it.
* Turn sc_wlabel into a flag, and don't set it automatically in DIOCWLABEL.
* If there is no label, disallow all I/O except to the raw partition.
* Don't allow I/O to `unused' partitions.
* Beginnings of support for block sizes other than 512 bytes.
Other minor changes.

119f3ea688 Various: 
Put WDF_ERROR in the wdc_softc, to avoid gratuitously forcing non-active drives
into single-sector mode on the next transfer.  Arrange to wait for an interrupt
after wdsetctlr(); this avoids long busy-wait delays, and gets rid of the
`extra interrupt' messages (except for one immediately after autoconfig on some
machines).  Replace some uses of wdsetctlr() with simply lowering wd->sc_state;
no point in forcing this immediately.  Allow control operations to time out.
Enable the warnings for long busy-wait delays by default.  Some other minor
things not worth mentioning.

86999439b2 number of changes: 
1. controller reset code moved into one function, called from more places now.
2. more places now do timeouts. TIPCAT code turned on.
3. blew away the unused WDOPENLOCK test code.
4. delay is now done using WDCNDELAY repetitions of DELAY(25). Up to 2.5 second
   pause accepted from controller (some controllers have some commands that are
   actually this slow)
5. some of the old timeout code was really whacked.

545cc18754 This patch allows the wd device driver to tell how big the disks are on 
WD1007-derived controllers. In this example, wdc0 is a WD1007-clone,
and wdc1 is a WD1003-clone. WD1007 controllers are generally ESDI
and IDE controllers.
wdc0 at 0x1f0-0x1f7 irq 14 on isa

fbecd3e987 Once more: some changes to the ioconf.c structure. It will now handle 
devices hanging off controllers, any kind of controller.
A device on isa0 is called at probe(self), then attach(self)
A controller on isa0 is called at probe(self), then all it's children with
    defined unit numbers are initialized by calling attach(subdev); next all
    subdevices with unit ? are initialized by calling attach(sundev).
Almost all device entry points is now like the vax/sun model (intr being
the weird one)
