Change function definitions using the identifier-list form used in the
1st edition of Kernighan and Ritchie's The C Programming Language, to
that of the parameter-type-list form described in the ANSI X3.159-1989
standard.

In ISO/IEC 9899:2023 drafts, there is only one form of function definition.
"N2432 Remove support for function definitions with identifier lists".

Use timeout_add_msec(9)

Use timeout_add_msec(9)

hz can simply be reduced has the code wants to wait
(period * hz) / 1000 [ticks] = period / 1000 [s] = period [ms].

With the zero check, this perfectly matches the millisecond version.

This conversion by itself also lifts the implicit expection of the period
to be evenly divisible by ten; in case it was not, integer division
would truncate it.

See /sys/wscons/wskbd.c for how the period is set up.

If you use sys/param.h, you don't need sys/types.h

Reduces the noise around the global ``ticks'' variable by renaming
all the local ones to ``nticks''.

Add support for the Sun Enterprise 450
Reduce the size of a GENERIC kernel by ~190k
Remove the nasty pointer/bus_space_handle_t casts
Adds debug bus_space code including the ability to trace
bus

Add support for the Sun Enterprise 450
Reduce the size of a GENERIC kernel by ~190k
Remove the nasty pointer/bus_space_handle_t casts
Adds debug bus_space code including the ability to trace
bus operations (it actually works now).

The following rules are now followed (and verfified by the debug
code):

1. A "bus_space_handle_t" may only be used with the
"bus_space_tag_t" that created it.
2. Only "bus_space_map()" may create "bus_space_handle_t"s.
3. A "bus_space_handle_t" may not be modified after it has
been created (other than being destroyed by "bus_space_unmap()").


Thanks to help from mcbride, marc, jason, drahn, to anyone that might
have slipped my mind at the moment.

First round of __P removal in sys

make this compile w/out pckbd (thanks marco for pointing this out)

If there are pckbd's, register ourselves to handle beeps... AXi's can now
squawk with the best of 'em.
