yangguo 75350f1ef0 Debugger: require debugger to be active when dealing with breaks.
This invariant will save us some head ache.
The changes to test-debug/DebugStub is due to the fact that it abuses
the ability to set break points in code that has no debug break slots.
This is now no longer possible.
