Code paths that create a PHPUnit_Framework_Warning end up serializing/unserializing globals unconditionally

[eferreira]

When PHPUnit is given a file with no test methods, with private test methods, with no public constructor, etc., it creates a PHPUnit_Framework_Warning object and "runs" it. Since this object has $backupGlobals === NULL, "running" it results in all the globals being serialized and then unserialized. In our environment there are globals that cannot be serialized, so this behavior breaks things and causes subsequent tests in the same suite to fail. So there needs to be a way to turn this behavior off. My suggestion is to have this behavior always be off by adding

    protected $backupGlobals = FALSE;

to the PHPUnit_Framework_Warning class.
