sim: Add hooks to implement event reference counting
We currently only support deleting an event if it is triggered and not
re-scheduled. This is fine for most native code. However, there are
cases where Python needs to count references to make sure that the
Python object stays live while the native object is live.
Generalise the mechanism used to implement by adding reference
counting hooks to the event base class:
* Event::incref()
* Event::decref()
These calls are used to increase and decrease the reference count of
an object. The default implementation in Event maintains backwards
compatibility with the existing AutoDelete feature by ignoring
incref() and deleting the event on decref() if it isn't scheduled
anymore.
For performance and backwards-compatibility reasons, these methods are
only called when the Managed/AutoDelete flag is set.
