Fix node exiting due to an exception being thrown rather than emitting
an 'uncaughtException' event on the process object when:
1. no error handler is set on the domain within which an error is thrown
2. an 'uncaughtException' event listener is set on the process

Also 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.

Fixes #3607 and #3653.

Notable changes:

* http_parser: Update to http-parser 1.2 to fix an unintentionally
  strict limitation of allowable header characters.
  (James M Snell) #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) #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) #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.
    More info is available at
    https://www.openssl.org/news/vulnerabilities.html#2016-0705
  - 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
    https://www.openssl.org/news/vulnerabilities.html#2016-0800
