[exim] Build fails with Events disabled

[Ian Zimmerman via Exim-users]

After reading the chapter on events in the Spec, I thought it was too
hairy even for my baroque taste, so I tried to compile without it.  I
got this:

smtp.c:1626:34: error: ‘transport_instance {aka struct
     transport_instance}’ has no member named ‘event_action’ (void)
     event_raise(sx->tblock->event_action, ^~

smtp.c:1637:36: error: ‘transport_instance {aka struct
       transport_instance}’ has no member named ‘event_action’ (void)
       event_raise(sx->tblock->event_action, ^~

smtp.c:1977:31: error: ‘transport_instance {aka struct
  transport_instance}’ has no member named ‘event_action’ (void)
  event_raise(sx->tblock->event_action, ^~

smtp.c:2075:34: error: ‘transport_instance {aka struct
     transport_instance}’ has no member named ‘event_action’ (void)
     event_raise(sx->tblock->event_action, US"dane:fail",
