Add recur_apoint_inday() and recur_event_inday().

To be used with llist_fn_match_t callbacks later.

I feel a bit ill adding those functions. This definitely is a hack.
Ultimately, there should be some generic recur_item_inday() function
that accepts both recurring apointments and events (or some wrapper
structure) instead of parameter galeere. This is not the right place to
fix that tho.
