locking primitive directly to lock it, since those will never attempt
to call printf() to display debugging information (and thus deadlock
on recursion into the kprintf_slock).
- Now compatible with MULTIPROCESSOR (requires other changes not yet
committed, but which will be later today).
- In addition to tracking simple locks, track exclusive spin locks.
- Count spin locks like we do sleep locks (in the cpu_info for this
CPU).
- Lock debug lists are now TAILQs, so as to make the locking order
more obvious when dumping the list.
Also, some suggestions from Bill Sommerfeld:
- SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED constants, which may be
defined in <machine/lock.h> (default to 1 and 0, respectively). This
makes it easier to support architectures which use test-and-clear
rather than test-and-set.
- Add __attribute__((__aligned__)) to the `lock_data' member of the
simplelock structure. This makes it easier to support architectures
which can only perform atomic operations on very-well-aligned memory
locations. NOTE: This changes the size of struct simplelock, and
will cause a version bump.
once for ipv6. This patch makes the ipv6 case pass NULLs in for fast
and slow timeouts iff defined(INET) and passes in the right function
if !defined(INET).

I place the rewritten version into the public domain. Fixes PR 5784.
rename gzip.c's decompress to de_compress. I emailed the author
of libbz back in December about this and haven't heard anything
since...
Thanks to enami tsugutomo for pointing this out.

While here, add an optimization to wakeup() suggested by Ross Harvey.
Add a new option "-S" to "nroff" and use "nroff -S" instead of "groff -S"
because "nroff" adds some other (moderately useful and important) options
to the "groff" execution.

backgammon(6). The use of write(2) for the message may seem odd, but
is used in another place in this game. (Actually, a lot of
backgammon(6) could do with being substantially cleaned up.)
