HTTP/2: removed support for NPN.
NPN was replaced with ALPN, published as RFC 7301 in July 2014.
It used to negotiate SPDY (and, in transition, HTTP/2).
NPN supported appeared in OpenSSL 1.0.1. It does not work with TLSv1.3 [1].
ALPN is supported since OpenSSL 1.0.2.
The NPN support was dropped in Firefox 53 [2] and Chrome 51 [3].
