Prevent ptrace on system processes. Avoids panic when attempting to ptrace pid 0, which has no parent.

Add a lock around the scheduler, and use it as necessary, including
...
in the non-MULTIPROCESSOR case (LOCKDEBUG requires it). Scheduler
lock is held upon entry to mi_switch() and cpu_switch(), and
cpu_switch() releases the lock before returning.
Largely from Bill Sommerfeld, with some minor bug fixes and
machine-dependent code hacking from me.

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. :-)

Reinstate P_FSTRACE, with different semantics:
...
* Never send a SIGCHLD to the parent if P_FSTRACE is set.
* Do not permit mixing ptrace(2) and procfs; only permit using the one that
was attached.

Fix various signal handling bugs:
...
* If we got a stopping signal while already stopped with the same signal,
the second signal would sometimes (but not always) be ignored.
* Signals delivered by the debugger always pretended to be stopping
signals.
* PT_ATTACH still didn't quite work right.
