The libevent 1 emulation is optional, you could embed libev without the
event.[ch] files.

It might be possible to supply an event_base_loopbreak function, although I
don't know if this is part of the libevent 1 API (the one libev emulates) or
libevent 2.

Maybe sth. like this (for event.c) works (this is not correct, so some
testing might be required):

   int event_base_loopbreal (struct event_base *base)
   {
     dLOOPbase;

     ev_break (EV_A_ EVBREAK_ONE);

     return 0;
   }

However, using libevent2 for libevent functions and libev for libev
functions (by embedding only the liubev core parts) would probably be the
best solution.
