Log Message:
- Shrink ipl_cookie_t from 32-bits to 16-bits (large enough to hold
  an SR value or an IPL_* constant).
- Take advange of the smaller ipl_cookie_t to shrink kmutex_t from
  16 bytes to 8 bytes by overlapping storage where possible.
- Implement a RAS-based _lock_cas() for mc68010 systems (Sun2).  See
  sun68k/sun68k/isr.c.

Tested on various m68k platforms, but NOT Sun2.  In any case, at least
Sun2 compiles now.
