2018d40811 Allocate kernel virtual address space for the U-area before allocating 
the new proc structure when performing a fork.  This makes it much
easier to abort a fork operation and return an error if we run out
of KVA space.

The U-area pages are still wired down in {,u}vm_fork(), as before.

d2924ae854 Prevent the session ID from disappearing if the session leader exits 
(thus causing s_leader to become NULL) by storing the session ID separately
in the session structure.  Export the session ID to userspace in the
eproc structure.

Submitted by Tom Proett <proett@nas.nasa.gov>.

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.  :-)

to the newly created process.

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.

Eliminate unused third arg to vm_fork().

a0a7429482 lots of changes: prototype migration, move lots of variables, definitions,

definitions.  standardize clock handling.  More changes than you'd want.

general prototypes.  Casts where necessary.
