Elliot Nunn 7fdc813d8f Reverse userspace sync primitives
Namely queues, semaphores, critical regions, event groups and
"notifications". The MP calls implementing these services have been
named after their MPLibrary wrapper functions. This convention will be
followed in the future (no more NKCreateEvent).
