Add MetaCursorTracker, a new helper for tracking the cursor sprite Under X, we need to use XFixes to watch the cursor changing, while on wayland, we're in charge of setting and painting the cursor. MetaCursorTracker provides the abstraction layer for gnome-shell, which can thus drop ShellXFixesCursor. In the future, it may grow the ability to watch for pointer position too, especially if CursorEvents are added to the next version of XInput2, and thus it would also replace the PointerWatcher we use for gnome-shell's magnifier. https://bugzilla.gnome.org/show_bug.cgi?id=705911

Clean up include macros mess The order and way include macros were structured was chaotic, with no real common thread between files. Try to tidy up the mess with some common scheme, to make things look less messy.
