Introduces 3 low level functions and updates the existing higher levels functions. The new primitives are has_body/1, body_length/1 and stream_body/1. In addition to that, a helper function init_stream/4 has been added. Streaming a body implies to decode the Transfer-Encoding and Content-Encoding used for the body. By default, Cowboy will try to figure out what was used and decode them properly. You can override this if you want to disable this behavior or simply support more encodings by calling the init_stream/4 function before you start streaming the body.
This new protocol option is a fun. It expects a single arg, the Req, and should only return a possibly modified Req. This can be used for many things like URL rewriting, access logging or listener-wide authentication. If a reply is sent inside the hook, then Cowboy will consider the request handled and will move on to the next one.

Certain user agents send slightly invalid media types, like the following: "text/html, image/gif, image/jpeg, ; q=.2, */; q=.2" The user agent with which this behavior was observed presented itself with the User-Agent string: "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (FlipboardProxy/0.0.5; +http://flipboard.com/browserproxy)"
The return value from the generate_etag/2 callback is expected to be a binary tagged with either weak or strong. This binary is quoted, and may be prefixed with W/ before it is set as the value of the ETag header in the response. For backwards compatibility with older handlers where the return value was expected to be a quoted binary a function has been added to parse any return values that are untagged binaries. All untagged binaries are expected to be a valid value for the ETag header.
