alt-svc issue 43: ALPN identifiers in Alt-Svc

(see <https://github.com/httpwg/http-extensions/issues/43>)

> ALPN identifiers from the ALPN spec have been defined in the context of negotiating the application protocol in TLS. In this context, they imply a layering above TLS.
> When used outside this context, there is an ambiguity, mainly for the http/1.1 token: does it refer to HTTP/1.1 over TLS, or can it refer also to HTTP/1.1 over TCP?
> The draft should resolve this ambiguity by stating that the http/1.1 identifier is used to identify HTTP/1.1 over TLS.

Right now we do not mention "http/1.1" at all. Should that change?

> In addition, a new identifier, h1c for example, could be defined to identify HTTP/1.1 over cleartext TCP, in order to allow using Alt-Svc to be used to target an HTTP/1.1 server over cleartext TCP.

Is this a use case we want to address?
