This commit is not only an early preview of HTTP/2, it is an
early preview of the new Cowboy architecture that will be
presented tomorrow in my talk. If you have found it before
the talk, great! It's not complete so you better go watch
the talk anyway.
This is a large commit.
The rfc7230 test suite adds many tests from the RFC7230 document.
Gun has been updated quite a bit recently, which broke the Cowboy
suites. This is now fixed with this commit.
A new hook onfirstrequest has been added. It was very useful during
debugging of the test suites.
The initial process code has changed a little; more changes are
expected with the switch to maps for options.
make docs: generate Markdown and man pages in doc/
make install-docs: install man pages to be usable directly
Docs are generated from the ezdoc files in doc/src/.
