kcar features an HTTP parser that will convert a bytestream into a
3-element array suitable for use as a Rack response. It is IO interface
agnostic, so it may be used with HTTP streams over Unix domain sockets,
regular files, FIFOs, StringIOs as well as traditional TCP sockets.

Changes:

* add Kcar::Parser#body_bytes_left= setter method

This allows us to properly get body_eof? to return true
in Kcar::Response for unchunked responses.
