split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

udpate license clauses on my code to match the new-style BSD licenses.
remove no-longer-valid wustl email address for me.
based on diff that rmind@ sent me.

no functional change with this commit.

don't call variables errno! including from userland breaks things!

- change the way to specify a bufq strategy. (by string rather than by number)
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)

Convert to new device buffer queue interface.

Approved by: Nathan J. Williams <nathanw@netbsd.org>

Conform bus_dmamem_{alloc,map} usage to bus_dma(9) specs.

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

Update for sys/buf.h/disksort_*() changes, plus make it compilable on
more systems.

Send the DMA, not KVA, addresses of I/O descriptors to the controller.

Use `busdma' macros.

Start an MI VMEbus framework.

Includes two sample drivers: IE ethernet driver (VME front-end to
dev/ic/i82586.c) and the XD disk driver, both converted from the
sparc versions.
