Security Update

### Notable changes

* **http**: Fix CVE-2015-8027, a bug whereby an HTTP socket may no longer have a parser associated with it but a pipelined request attempts to trigger a pause or resume on the non-existent parser, a potential denial-of-service vulnerability. (Fedor Indutny)

* **openssl**: Upgrade to 1.0.2e, containing fixes for:

- CVE-2015-3193 "BN_mod_exp may produce incorrect results on x86_64", an attack may be possible against a Node.js TLS server using DHE key exchange. Details are available at <http://openssl.org/news/secadv/20151203.txt>.

- CVE-2015-3194 "Certificate verify crash with missing PSS parameter", a potential denial-of-service vector for Node.js TLS servers using client certificate authentication; TLS clients are also impacted. Details are available at <http://openssl.org/news/secadv/20151203.txt>.

(Shigeki Ohtsu) [#4134](https://github.com/nodejs/node/pull/4134)

* **v8**: Backport fix for CVE-2015-6764, a bug in `JSON.stringify()` that can result in out-of-bounds reads for arrays. (Ben Noordhuis)
