Fix the atomic_*_32 operations. These were written before I had the ability
to test them properly and before I had a working knowledge of GCC asm
constraints.

Oops, this was meant to be done in a later commit but I goofed.
This commit was meant to add entries for extintr.c (used partially by the
new clock/timecounter which is coming in a later commit) and entries for
bits of DDB source, which is also coming soon.

Fix a race condition in pthread_join(). All of the following must occur
atomically:
1) Search _thread_list for the thread to join.
2) Search _dead_list for the thread to join.
3) Set the running thread as the joiner.
While we're at it, fix a race in the case where multiple threads try to
join on the same thread. POSIX says that the behavior of multiple joiners
is undefined, but the fix is cheap as a result of the other fix.

- Add trylock variants of shared and exclusive locks.
- The sx assertions don't actually need the internal sx mutex lock, so
don't bother doing so.
- Add a new assertion SX_ASSERT_LOCKED() that asserts that either a
shared or exclusive lock should be held. This assertion should be used
instead of SX_ASSERT_SLOCKED() in almost all cases.
- Adjust some KASSERT()'s to include file and line information.
- Use the new witness_assert() function in the WITNESS case for sx slock
asserts to verify that the current thread actually owns a slock.

- Always use the proc lock of the task leader to protect the peers list of
processes.
- Don't construct fake call args and then call kill(). psignal is not
anymore complicated and is quicker and not prone to locking problems.
Calling psignal() avoids having to do a pfind() since we already have a
proc pointer and also allows us to keep the task leader locked while we
kill all the peer processes so the list is kept coherent.
- When a kthread exits, do a wakeup() on its proc pointers. This can be
used by kernel modules that have kthreads and want to ensure they have
safely exited before completely the MOD_UNLOAD event.

the locks held by this process temporarily during an interrupt.
- Close a more fatal race condition when removing a lock from a list.
Removing a lock from the list entails both decrementing the count of

a notch to replace the gap left by the removed item. Wrap these
operations in a critical section.
