lip service to making ISA support machine-independent. This is the first
...
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific. eventually (when other ports with ISA
busses really start using this code), more 'high-level' ISA support will
live here.

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.

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.

support for making dev->id_alive be set, this is for iostat to
...
find disk devices. wee bit of a kludge. sub-device attach()
routines must now return 1 for successful attach(), 0 otherwise.
Other bsd's do this too..

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)

wd driver would fail on calling wdgetctlr() for older drives and
...
controllers. New behaviour is that if the standard method fails, try
to recalibrate the drive. Success means the drive exists. patch by
hpeyerl@novatel.cuc.ab.ca (who owns several of these historical
artifacts)

dmesg output at boottime now tries to print out information as

soon as it is available. The output looks much more like Sunos.
