HTTP/2 C library and tools

Nghttp2 v1.0.0

We finally released nghttp2 v1.0.0! Hooray!

This release is based on v0.7.15, and does not introduce any feature, but changed existing API in backward incompatible way. We hope these changes will improve usability of our API. Please read this article to upgrade from older release.

Now that HTTP/2 and HPACK RFCs are published, v1.0.0 uses h2 and h2c as primary protocol identifiers. For TLS connections, all bundled applications still accept h2-14 and h2-16. h2-14 and h2-16 will be removed in the future release. On the other hand, HTTP Upgrade now only accepts h2c only, and h2c-14 is not acceptable anymore.
