Version 1.4.2

Backported changes from version 2:

• Version 2.0.10 - 2017-03-13
  • Mcrypt can now be used on PHP < 5.3.7 if you're not on Windows.
• Version 2.0.9 - 2017-03-03
  • More Psalm integration fixes.
• Version 2.0.8 - 2017-03-03
  • Prevent function already declared error for random_int() caused by misusing
    the library (really you should only ever include lib/random.php and never any
    of the other files). See #125.
• Version 2.0.6, 2.0.7 - 2017-02-27
  • Just updates to psalm.xml to silence false positives.
• Version 2.0.5 - 2017-02-27
  • Run random_compat through the static analysis tool, psalm,
    as part of our continuous integration process.
  • Minor readability enhancements (#122
    and several docblock changes).
• Version 2.0.4 - 2016-11-07
  • Don't unnecessarily prevent mcrypt_create_iv() from being used.
    See #111.
• Version 2.0.3 - 2016-10-17
  • Updated lib/error_polyfill.php to resolve corner cases.
  • The README was updated to help users troubleshoot and fix insecure environments.
  • Tags will now be signed by the GnuPG key used by the security team at Paragon Initiative Enterprises, LLC.
• Version 2.0.2 - 2016-04-03
  • Added a consistency check (discovered by Taylor Hornby in his PHP encryption library). It wasn't likely causing any trouble for us.
