qstatemachine: add methods detect when a machine has processed an event

currently when adding an event it is not possible to know when processing
it has finished.
In particular if the event is ignored no method is called.
Adding virtual methods to the private implementation (binary compatibility).
These methods allow for extended automatic testing of the state machines.

(cherry picked from commit e7feb956280105113b3e58f12e5f32f54199a95a)
