HTTP/2 protocol when using HTTPS. Programs that must disable HTTP/2
can do so by setting [Transport.TLSNextProto] (for clients) or
[Server.TLSNextProto] (for servers) to a non-nil, empty
map. Alternatively, the following GODEBUG settings are
currently supported:

	GODEBUG=http2client=0  # disable HTTP/2 client support
	GODEBUG=http2server=0  # disable HTTP/2 server support
	GODEBUG=http2debug=1   # enable verbose HTTP/2 debug logs
