py-h11: Import py-h11-0.7.0 as www/py-h11

This is a little HTTP/1.1 library written from scratch in Python,
heavily inspired by hyper-h2.

It's a "bring-your-own-I/O" library; h11 contains no IO code
whatsoever. This means you can hook h11 up to your favorite network
API, and that could be anything you want: synchronous, threaded,
asynchronous, or your own implementation of RFC 6214 - h11 won't
judge you. (Compare this to the current state of the art, where
every time a new network API comes along then someone gets to start
over reimplementing the entire HTTP protocol from scratch.)
