This code adds a new Bufferevent type that is only compiled when the openssl library is present. It supports using an SSL object and an event alert mechanism, which can either be an fd or an underlying bufferevent. There is still more work to do: the unit tests are incomplete, and we need to support flush and shutdown much better. Sometimes events are generated needlessly: this will hose performance. There's a new encrypting proxy in sample/le-proxy.c. This code has only been tested on OSX, and nowhere else. svn:r1382
