[RFC] Modify resolution order of count_elements handler

Hi, I'd like to fix the resolution order of Countable::count() vs count_elements handler. Currently, things are done like this: 1) check if the object implements countable, if so, call it's method 2) if not, check if count_elements handler is defined, if so, use it. This is a problematic order of resolution, and I'd like to inverse it. Why? Because : 1) it is inconsistent with other handlers 2) it makes it impossible to be userland friendly while saving a method call when it's possible. Currently, there are 3 possibilities: 1) the internal class doesn't use count_elements handler -> No problem with the change 2) the internal class uses only the handler -> It's not userland friendly, the change won't help, so it needs to be fixed anyway 3) both the handler and the method are used -> the handler was never called directly, such classes will need a fix after that resolution order change. Userland classes are not affected. I can and will take care of every problems occuring in classes in php-src (2 or 3, mostly SPL).
