  How can I fix thee?  let me count the ways...

  * pass a chunked body always (no-body requests don't go chunked).

  * validate that the C-L counted body length doesn't change.

  * follow RFC 2616 for C-L / T-E in the request body C-L / T-E
    election logic.

  * do not forward HTTP/1.0 requests as HTTP/1.1, unless the admin
    configures force-proxy-request-1.1

  * conn was illegible, use 2.0's p_conn.
