SSLServer implements a very simple set of functionality.  It will be very
easy to replicate it using the M2Crypto API.  You just need a startService
(and maybe a privilegedStartService) that calls the M2Crypto server setup
API and a stopService that calls the M2Crypto server shutdown API (which I
hope is just IListeningPort.stopListening).

_AbstractServer is private, so you shouldn't touch it.  You can look at its
implementation (barely a page) to get some hints about what to write, though.
