description:
Reorganize and bump VM related constants.

- sync VM_MAXUSER_ADDRESS and VM_MAX_ADDRESS with other hp300 derived ports
  and use same definitions for USRSTACK as other m68k ports
  (no worth to have sun3/sunos compat in these days)
- remove unused KUSER_AREA
- bump MAXTSIZ, MAXDSIZ, and MAXSSIZ

These changes allow my 64MB TT030 build pkgsrc/textproc/icu
which seems to require >200MB VA space.
(note our current 040/060 pmap implementation can't handle >224MB VA size)
