0f2ecb72f6 lots of changes: prototype migration, move lots of variables, definitions, 
and structure elements around.  kill some unnecessary type and macro
definitions.  standardize clock handling.  More changes than you'd want.

22dff5862a Removed the user area protection gunk I painstakingly removed in revision 
1.9.  It has not been necessary since then due to a segment fixup made to
machdep.c that prevents access to anything above MAX_VMUSER_ADDRESS.

aa381d0e73 vm_protect() of the user area is no longer required for i386 machines; the 
protection is implemented by adjusting the bounds of the user segment
descriptors.

5705dde7e9 Disallow access to the user pages, where the kernel stack is stored. This 
is effected in useracc(), and also by a vm_protect() in vm_fork() for i386
CPUs.  Without the latter a write to the user area, say USRSTACK+1000,
would hang a 386-based system.
