Implement address space sharing (by keeping ref counts on the vmspace
...
structure). Many thanks to Chuck Cranor for debugging assistence.

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many
...
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

add thread_sleep_msg() that takes a wait message, and change thread_sleep()

of this.

Fix an inconsistency that came in with Lite: setrq() was renamed to
...
setrunqueue(), but remrq() was never renamed. Rename remrq() to
remrunqueue(). Also, move remrunqueue() prototype from vm/vm_extern.h
to sys/proc.h, so that it's in the same place as the setrunqueue() prototype
and other related prototypes.

add sequential swap device support, supplied by hibler many moons ago.
...
(Note that it needs config support, too, which isn't there yet, but
might be soon...) Also, general cleanup. use NODEV to terminate swdevt,
so that sparc port (and future) is happy.
