Release Name: 3.7.0

Notes:
unicorn 3.7.0 - minor feature update

Unicorn is an HTTP server for Rack applications designed to only serve
fast clients on low-latency, high-bandwidth connections and take
advantage of features in Unix/Unix-like kernels.  Slow clients should
only be served by placing a reverse proxy capable of fully buffering
both the the request and response in between \Unicorn and slow clients.

Changes:

* return 414 (instead of 400) for Request-URI Too Long
* strip leading and trailing linear whitespace in header values

User-visible improvements meant for Rainbows! users:

* add :ipv6only "listen" option (same as nginx)

    strip trailing and leading linear whitespace in headers
    
    RFC 2616, section 4.2:
    > The field-content does not include any leading or trailing LWS:
    > linear white space occurring before the first non-whitespace
    > character of the field-value or after the last non-whitespace
    > character of the field-value. Such leading or trailing LWS MAY be
    > removed without changing the semantics of the field value. Any LWS
    > that occurs between field-content MAY be replaced with a single SP
    > before interpreting the field value or forwarding the message
    > downstream.

    http_parser: new add_parse method
    
    Combines the following sequence:
    
       http_parser.buf << socket.readpartial(0x4000)

    Into:
    
       http_parser.add_parse(socket.readpartial(0x4000))
