Add:core: event_call_callback infrastructure|

To be used from threads that want to call the callback
from the main(gui) thread. Users must provide
synhronization of the callback data.
Difference with using timeouts are:
Threads can have own timers
Timer events are low priority, this must be called ASAP.
