Remove "register_globals" support codes from php/php_binary serializer #2233
This patch removes "register_globals" support codes from php/php_binary serializer.
This patch is a code cleanup. However, there could be compatibility issue when user mixing old PHP (less than PHP 5.4.0) that supports "register_globals" (i.e. Variables that are registered by session_register()) When session_register()ed variables are undefined, it results in error. Since session_register() is removed in PHP 5.4.0, PHP 5.4.0 or later has no issues.
If there is no comment, I'll merge this in a few days.
