Move SSL setup out of reds_accept_ssl_connection

To allow setup of an SSL client, from a passed in client
socket, move all the SSL client initialization code out
of reds_accept_ssl_connection and into a new method called
reds_init_client_ssl_connection

* server/reds.c: Introduce reds_init_client_ssl_connection
