[RFC] Remove deprecated functionality in PHP 7

Hi internals! We currently have a number of deprecated features, which we likely want to remove in PHP 7. I've created a tracking RFC listing deprecated functionality (if I missed something, please tell): https://wiki.php.net/rfc/remove_deprecated_functionality_in_php7 I expect many of these are no-brainers (like assigning new by-reference), but other items like removal of ext/mysql may need additional consideration. Unless there are items that are particularly contested, I'd like to handle the bulk of these in a single vote and only have separate votes for ext/ereg and ext/mysql, as these are arguably more intrusive. Thanks, Nikita
