Subject: r11794: - fixed a valgrind error in libnet, caused by using a stack
 variable   after the function has returned (the *address variable was
 assigned   into the state).

- changed libnet to use event_context_find() instead of
  event_context_init(), so it works as a child of existing code that
  uses a event context
(This used to be commit 47ceb2d3558304b4c4fb00582fb25a885cea2ef5)
