treewide: macros lambda-esque screen iteration

Browse Source 
iterating over screen list via lambda-esque macros calls like this

    DIX_FOR_EACH_SCREEN({
        do_something
    });

withing the body, the iterator variables `walkScreenIdx` and `walkScreen`
are defined and can be directly used (read-only). the code inside the body
is running in a separate scope.
