OpenSSL has a per-thread error stack, and really doesn't like you leaving errors on the stack. Rather than discard the errors or force the user to handle them, this patch pulls them off the openssl stack and puts them on a stack associated with the bufferevent_openssl. If the user leaves them on the stack then, it won't affect any other connections. This bug was found by Roman Puls. Thanks! svn:r1481
