Log Message:
Update lang/nodejs4 to 4.3.0.

Note that this release includes a non-backward compatible change
to address a security issue. This change increases the version
of the LTS v4.x line to v4.3.0. There will be no further updates
to v4.2.x.

- http: fix defects in HTTP header parsing for requests and
  responses that can allow request smuggling (CVE-2016-2086)
  or response splitting (CVE-2016-2216). HTTP header parsing
  now aligns more closely with the HTTP spec including
  restricting the acceptable characters.
- http-parser: upgrade from 2.5.0 to 2.5.1
- openssl: upgrade from 1.0.2e to 1.0.2f. To mitigate against
  the Logjam attack, TLS clients now reject Diffie-Hellman
  handshakes with parameters shorter than 1024-bits, up from
  the previous limit of 768-bits.
- introduce new --security-revert={cvenum} command line flag
  for selective reversion of specific CVE fixes
- allow the fix for CVE-2016-2216 to be selectively reverted
  using --security-revert=CVE-2016-2216
