2016-03-04 Version 0.10.43 (Maintenance) Release

Notable changes:

* http_parser: Update to http-parser 1.2 to fix an unintentionally
  strict limitation of allowable header characters.
  (James M Snell) https://github.com/nodejs/node/pull/5242
* domains:
  - Prevent an exit due to an exception being thrown rather than
  emitting an 'uncaughtException' event on the `process` object when
  no error handler is set on the domain within which an error is
  thrown and an 'uncaughtException' event listener is set on
  `process`. (Julien Gilli) https://github.com/nodejs/node/pull/3887
  - Fix an issue where the process would not abort in the proper
  function call if an error is thrown within a domain with no error
  handler and `--abort-on-uncaught-exception` is used.

* openssl: Upgrade from 1.0.1r to 1.0.1s
  (Ben Noordhuis) https://github.com/nodejs/node/pull/5508
  - Fix a double-free defect in parsing malformed DSA keys that may
    potentially be used for DoS or memory corruption attacks. It is
    likely to be very difficult to use this defect for a practical
    attack and is therefore considered low severity for Node.js users.

  - Fix a defect that can cause memory corruption in certain very rare
    cases relating to the internal `BN_hex2bn()` and `BN_dec2bn()`
    functions. It is believed that Node.js is not invoking the code
    paths that use these functions so practical attacks via Node.js
    using this defect are _unlikely_ to be possible. More info is
    available at
    https://www.openssl.org/news/vulnerabilities.html#2016-0797
  - Fix a defect that makes the CacheBleed Attack
    (https://ssrg.nicta.com.au/projects/TS/cachebleed/) possible.
    This defect enables attackers to execute side-channel attacks
    leading to the potential recovery of entire RSA private keys. It
    only affects the Intel Sandy Bridge (and possibly older)
    microarchitecture when using hyper-threading. Newer
    microarchitectures, including Haswell, are unaffected. More info
    is available at
    https://www.openssl.org/news/vulnerabilities.html#2016-0702
  - Remove SSLv2 support, the `--enable-ssl2` command line argument
    will now produce an error. The DROWN Attack
    (https://drownattack.com/) creates a vulnerability where SSLv2 is
    enabled by a server, even if a client connection is not using
    SSLv2. The SSLv2 protocol is widely considered unacceptably broken
    and should not be supported. More information is available at
