Notable changes:

* buffer: Zero-fill excess bytes in new `Buffer` objects created with
  `Buffer.concat()` while providing a `totalLength` parameter that
  exceeds the total length of the original `Buffer` objects being
  concatenated. (Сковорода Никита Андреевич)
* http:
  - CVE-2016-5325 - Properly validate for allowable characters in the
    `reason` argument in `ServerResponse#writeHead()`. Fixes a
    possible response splitting attack vector. This introduces a new
    case where `throw` may occur when configuring HTTP responses,
    users should already be adopting try/catch here. Originally
    reported independently by Evan Lucas and Romain Gaucher.

  - Invalid status codes can no longer be sent. Limited to 3 digit
    numbers between 100 - 999. Lack of proper validation may also
    serve as a potential response splitting attack vector. Backported
    from v4.x. (Brian White)
* openssl: Upgrade to 1.0.1u, fixes a number of defects impacting
  Node.js: CVE-2016-6304 ("OCSP Status Request extension unbounded
  memory growth", high severity), CVE-2016-2183, CVE-2016-6303,
  CVE-2016-2178 and CVE-2016-6306.
* tls: CVE-2016-7099 - Fix invalid wildcard certificate validation
  check whereby a TLS server may be able to serve an invalid wildcard
  certificate for its hostname due to improper validation of `*.` in
  the wildcard string. Originally reported by Alexander Minozhenko
  and James Bunton (Atlassian). (Ben Noordhuis)
