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".

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

Make the "machine xir" ddb command work on machines with uperf(4) on ebus(4).

nuke terms 3 & 4

branches: 1.3.4;

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.

Some PCI machines do not implement the uperf registers. Those that do
provide an 'sc at ebus'. Use that instead of a direct attachment of
uperf to psycho.
