/**
* Common include for magic quotes files
*
* "Correct" behaviour is defined as that of PHP 5.2.2 and (so far) above:
* - $_GET, $_POST, $_COOKIE and $_REQUEST are treated
* - All of the above variables's keys and values are treated
*
* Fixed exceptions:
* - PHP < 5.2.2 keys of order 1 array values are not escaped
* - 5.0.0 >= PHP < 5.1.0 keys are escaped even when magic quotes is off
* - PHP < 5.0.0 keys of order 1 scalar values are not escaped
* - PHP < 4.3.4 keys of all scalar values are not escaped
