HTTP/2 C library and tools

Nghttp2 v0.7.1

We just released nghttp2 v0.7.1. The library documentation is still based on h2-14. nghttp, nghttpd, nghttpx and h2load additionally advertise h2-16 ALPN token to interop with the implementations which require h2-16.

This release fixes GOAWAY handling to conform to the HTTP/2 specification. TLS read/write error in nghttp, nghttpd, nghttpx and h2load has been fixed. We enabled TLS session ticket with automatic key rotation in nghttpx. We also add an option to specify key parameter from file (but without automatic rotation) to nghttpx to share same keys with multiple instances. For documentation wise, man pages are now now generated using Sphinx. We don’t use help2man anymore.
