40c08923a8 XXX LOCKING XXX of allproc; DDB runs with interrupts blocked, and MD 
code should suspend other processors, so this probably isn't a problem,
but the comment is added anyhow.

01a8cffe77 Add a read/write lock to the proclists and PID hash table. Use the 
write lock when doing PID allocation, and during the process exit path.
Use a read lock every where else, including within schedcpu() (interrupt
context).  Note that holding the write lock implies blocking schedcpu()
from running (blocks softclock).

PID allocation is now MP-safe.

Note this actually fixes a bug on single processor systems that was probably
extremely difficult to tickle; it was possible that schedcpu() would run
off a bad pointer if the right clock interrupt happened to come in the
middle of a LIST_INSERT_HEAD() or LIST_REMOVE() to/from allproc.

2715b812d1 Rework the process exit path, in preparation for making process exit 
and PID allocation MP-safe.  A new process state is added: SDEAD.  This
state indicates that a process is dead, but not yet a zombie (has not
yet been processed by the process reaper).

SDEAD processes exist on both the zombproc list (via p_list) and deadproc
(via p_hash; the proc has been removed from the pidhash earlier in the exit
path).  When the reaper deals with a process, it changes the state to
SZOMB, so that wait4 can process it.

Add a P_ZOMBIE() macro, which treats a proc in SZOMB or SDEAD as a zombie,
and update various parts of the kernel to reflect the new state.

eff41cf3b1 Implement cpu_wait(), and move the call to tss_free() from switch_exit() 
to cpu_wait(); tss_free() may block, and thus requires a valid context.

32e1fd0d03 Move the call of cpu_wait() out of the wait4() functions, and into the 
body of reaper(), right before the call to uvm_exit().  cpu_wait() must
be done before uvm_exit() because the resources it frees might be located
in the PCB.

7f53187a85 From Bill Studenmund: unlock the fdescfs "/dev/tty" vnode before calling

Squashes the somewhat bizarre lossage I was observing w/ more(1), sudo(1),
etc.

fce05250f9 more cleanup: 
remove simplelockrecurse, lockpausetime and PAUSE():
none of these serve any purpose anymore.
in the LOCKDEBUG functions, expand the splhigh() region to
cover the entire function.  without this there can still be races.
