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.
