Add protocol specific data
Rework Nikos Mavrogiannopoulos's ALPN support

Use protocol data functionality to hold configure ALPN protocols. Since
the complexity increased and there wasn't a clear use case, support only
a single TLS extension at a time per listener: TLS or ALPN. Complex
configurations involving both ALPN and SNI can be accomplished by using
configuring SNIProxy to proxy to another of its own listeners over a
UNIX socket to examine the other TLS extension. Use an additional
protocol argument toggle between SNI and ALPN TLS extensions.
