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.

ok jason@, deraadt@
