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.

eda6e4cca4 Address PR bin/7623: if the filesystem is so small (or segment size so large) 
that not enough segments are available for the second superblock, or to have
MIN_FREE_SEGS free for work room for the cleaner, newfs_lfs will now exit
with an error.

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.
