Kent Overstreet ebc6f76a66 six locks: Simplify wait lists 
This switches to a single list of waiters, instead of separate lists for
read and intent, and switches write locks to also use the wait lists
instead of being handled differently.

Also, removal from the wait list is now done by the process waiting on
the lock, not the process doing the wakeup. This is needed for the new
deadlock cycle detector - we need tasks to stay on the waitlist until
they've successfully acquired the lock.
