13e3f9e5f1 Add an input device function to convert keycodes to evdev codes
This adds a virtual function to ClutterInputDevice to translate a
keycode from the hardware_keycode member of ClutterKeyEvent to an
evdev keycode. The function can fail so that input backends that don't
have a sensible way to translate to evdev keycodes can return FALSE.
There are implementations for evdev, wayland and X. The X
implementation assumes that the X server is using an evdev driver in
which case the hardware keycodes are the evdev codes plus 8.

1dc7c45438 x11: Do not try to access private structures
ClutterInputDeviceX11 has been made private, so we cannot access it from
outside of clutter-input-device-core-x11.c. We should have simple
accessors for the min/max keycode, which is the only detail that we use.

6da51f6ed3 device/x11: Store min/max keycode in the XI device class
The generic device class shouldn't have the minimum and maximum keycode,
since no other input backend provides those.

431200f40d device: Add keys and axes accessors
Allow retrieving the number of keys and axes, since we provide the API
to iterate over them both.

1b1e77b469 event/x11: Rework the way we translate X11 events
This is a lump commit that is fairly difficult to break down without
either breaking bisecting or breaking the test cases.

The new design for handling X11 event translation works this way:

  - ClutterBackend::translate_event() has been added as the central
    point used by a ClutterBackend implementation to translate a
    native event into a ClutterEvent;

  - ClutterEventTranslator is a private interface that should be
    implemented by backend-specific objects, like stage
    implementations and ClutterDeviceManager sub-classes, and
    allows dealing with class-specific event translation;

  - ClutterStageX11 implements EventTranslator, and deals with the
    stage-relative X11 events coming from the X11 event source;

  - ClutterStageGLX overrides EventTranslator, in order to
    deal with the INTEL_GLX_swap_event extension, and it chains up
    to the X11 default implementation;

  - ClutterDeviceManagerX11 has been split into two separate classes,
    one that deals with core and (optionally) XI1 events, and the
    other that deals with XI2 events; the selection is done at run-time,
    since the core+XI1 and XI2 mechanisms are mutually exclusive.

All the other backends we officially support still use their own
custom event source and translation function, but the end goal is to
migrate them to the translate_event() virtual function, and have the
event source be a shared part of Clutter core.
