Avoid unnecessary start time calculations

Rename recur_*_inday() to recur_*_find_occurrence() and use the new
functions whenever we actually care about the start time of an
occurrence.

Reintroduce recur_*_inday() as wrappers to recur_*_find_occurrence() and
pass NULL as start time buffer (which means "skip start time
calculation"). Keep using these when we only want to know if a recurrent
item belongs to a specific day but do not care about the actual start
time.
