mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

thorpej ce340c6ca5 Also pass fork1() a struct proc **, in case the caller wants a pointer

thorpej 740f872797 New vfork(2) implementation, whith semantics matching those of the original
3BSD vfork(2), i.e. share address space w/ parent and block parent.

Keep statistics on the total number of forks, the number of forks that
block the parent, and the number of forks that share the address space
with the parent.
