Lots of changes for SSL enabled pubsub:
Pubsub libraries are now SSL enabled by default, so that we can talk SSL from a perl client. To do this we need another entry point from SWIG into the event code, event_register_withssl. At the same time there is a new entry point called event_set_sockbufsizes that calls a new pubsub entry point pubsub_set_sockbufsizes. The problem is that current swig generates code that does not compile, and since I don't know nothing about swig, I just hand crafted the two new routines that needed in event_wrap.c and the few extra lines that go into event.pm. Also change all the link lines to include the ssl/crypto libraries when linking.
