update_keycodes_iter() currently has 4(!) levels of nested loops, which makes the logic (especially the break/continue statements) difficult to understand. The logic also appears to continue looping uselessly after a given keycode has already been added to a keybind. Refactor by adding some small utility functions: - keybind_contains_keycode() - keybind_contains_keysym() - keybind_contains_any_keysym() No functional change intended.
