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.

5a17003403 Some changes inspired by Bruce Evans's driver: 
Consolidate error reporting in one function.  Actually use the dk_status and
dk_error fields, and pass around only the error bit to avoid lots of unneeded
assignments and tests.  No functional differences.

55a9a547a2 from Soeren Schmidt <sos@login.dkuug.dk>: 
Basically it does a timeout on lost interrupts, starting the operation
again and logging and error message on the console.
additionally fixes some of the (newer ending) while loops
(that made it work with two IDE disks !)

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.

2cb34d6d65 added a missing {/} pair that barsoom seems to have taken out, but 
which the standard 386bsd 0.1 driver did have. This is for a piece of
code in the bad block handling. found/fixed by hpeyerl.
