httparse is a http1 stateless push parser. This not only speeds up parsing right now with sync io, but will also be useful for when we get async io, since it's push based instead of pull. BREAKING CHANGE: Several public functions and types in the `http` module have been removed. They have been replaced with 2 methods that handle all of the http1 parsing.
