ALPN for Gemini

ALPN is standardized in RFC 7301. It is a name that is sent to the TLS server to indicate the application it wants to use. It would allow, for instance, the same machine to run HTTPS and Gemini on the same port. All it needs is registration of ALPN for Gemini and its use by Gemini clients and servers.

Question: do existing libraries make it easy for the server *and the client* to use ALPN?
