x11: Add a Keymap ancillary object We should try to abstract everything that is related with the key mapping to its own object, to avoid complicating ClutterBackendX11 any further.

x11: Add keymap direction query We should use the Xkb API to query the direction of the key map, depending on the group. To get a valid result we need to go over the Unicode equivalents of the key symbols for each group, so we should cache the result. The code used to query and cache the key map direction is taken from GDK. https://bugzilla.gnome.org/show_bug.cgi?id=705779

x11: Hide all private symbols The x11 backend exposes a lot of symbols that are meant to only be used when implementing a subclassed backend, like the glx and eglx ones. The uninstalled headers are also filled with cruft declarations of functions long since removed. Let's try to clean up this mess.

x11: Ignore num lock / scroll lock for event state As x11 considers num lock and scroll lock to be modifiers, code that checks for an exact modifier combination will fail if naively done when num lock or scroll lock are turned on. Applications that want to ignore these modifiers will need to use XKB to manually mask out the modifier state. As it is very unlikely that applications will want to care about the state of num lock or scroll lock for key press/key release events, mask out the num lock and scroll lock keys automatically. https://bugzilla.gnome.org/show_bug.cgi?id=690664
