hooks: add and use _fast callback function

Browse source 
Add a _fast callback function that skips the version and method check.
We can use this in places where performance is critical when we do the
check out of the critical loops.

Make all system methods _fast calls. We expect them to exist and have
the right version. If we add new versions we can make them slow.
