initialize events: prevents libevent2 from crashing

clminibufev and resizeev are two globally defined event, and thus
guaranteed to be zeroed.  While OpenBSD' libevent1 is fine when
calling event_pending on such events, libevent2 complains and,
probably depending on which flags were used, crashes.

Prompted and tested by Andrea Feletto, thanks!
