Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
...
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.

Get rid of `bus_type_t' and use BUS_ADDR() (in sbus_bus_map()) to construct
...
a `bus_addr_t' to pass on to bus_space_map().
Drop `va' argument from sbus_bus_map(); it should not be used by MI Sbus
drivers.

- allow for sbus node name matching
- get clock frequency from prom property.

Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point
...
in each tty driver to indirect through it.
This allows tty line-disciplines to handle poll(2) system calls.

Add a `device class' interrupt level argument (from machine/intr.h)
...
to bus_interrupt_establish().
It's currently only used in sparc64/dev/psycho.c to assign a CPU interrupt
level to devices in PCI slots.

Implement the more flexiable `evcnt' interface as discussed (briefly) on

tech-kern and now documented in evcnt(9).

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.

Check presence of Sbus interrupt properties before using them.

Only one case is known to trigger this omission: a Sparc Classic
configured as X terminal.
