[APCu] A new polyfill for the legacy APC users

Now that we know that `apc_*` functions are legacy and `apcu_*` is the only way in PHP7, I propose to move forward with this polyfill. Let's replace all usages of `apc_*` in Symfony and elsewhere by their `apcu_*` equivalent and add a deps on this new polyfill to cope with legacy `apc` users.
