To me,
- arg = ev->event.arg;
+ arg = event_periodic_callback_get_arg(ev);does not feel too much of a win. But it may provide some flexibility for future refactoring.

Yea I wanted to not expose the internal event struct to the user, they should only deal with event_periodic_callback_t

Contribution description
event_periodic_callback_get_arg()This is a purely aesthetic addition: When initializing an event, e.g. to measure a sensor, I want to have a locally visible
static lm75_t lm75_devthat I use as the event argument.I can access this in the callback, but if I want to access it outside the callback, e.g. to re-init the sensor after the callback was suspended, I have to access
event->event.argwhich feels dirty.Instead, add a nice getter function that does the same.
event_callback_oneshot()An easy helper to execute a function by the event thread, to be called e.g. in an interrupt or by another function that is not supposed to block.
