f749858df3 evdev: remove dead code
ClutterDeviceManager uses g_object_new directly, to pass the
necessary properties down.

a3557f7a2f evdev: fix X11 to evdev keycode translation
Hardware keycodes in Clutter events are x11 keycodes, which are
the same as evdev + 8, but we need to reverse the translation when
explicitly asked for an evdev keycode.

26b2852601 evdev: add a way for applications to tweak how devices are opened
In some cases, applications (or actually, wayland compositors)
don't have the required permissions to access evdev directly, but
can do so with an external helper like weston-launch.

Allow them to do so with a custom callback that replaces the regular
open() path.

d0d1b562bd evdev: Fix use of the common XKB code for the evdev device
In commit 8f4e39b6d7 the Wayland code was updated to use the new
xkbcommon API. This involved changing the common XKB code shared with
the evdev input backend. However the evdev input backend was not
modified so it wouldn't compile. This patch just makes a minor change
to update it.

8f4e39b6d7 Port to new Wayland and xkbcommon APIs
For Wayland, this is mostly the input protocol having changed, although
there's also the SHM pool API, the cursor API, as well as fullscreen and
ping.

Also port to the new (months-old) xkbcommon API, as used by Weston 0.95.
This involves having xkbcommon manage the state for us, where
appropriate.  Fans of multi-layout keyboards (or just caps lock) will no
doubt appreciate these changes.

99a7406d01 evdev: Swap the numbers for the middle and right buttons
The ordering of the evdev button numbers is the opposite of the
order in Clutter (the middle button is 3 instead of 2) so we need to
manually map the button numbers when creating a ClutterButtonEvent.

0e4c6d0a87 Deprecate clutter_threads_enter()/leave()
Acquiring the Clutter lock to mark critical sections is not portable,
and not recommended to implement threaded applications with Clutter.

The recommended pattern is to use worker threads, and schedule UI
updates inside idle or timeout handlers within the main loop. We should
enforce this pattern by deprecating the threads_enter()/leave()
functions. For compatibility concerns, we need internal API to acquire
the main lock during frame processing dispatch.

3c6a0cdc61 evdev: Adds api to release/reclaim the evdev devices
Clutter applications using evdev are typically fullscreen applications
associated with a single virtual termainal. When switching away from
the applications associated tty then Clutter should stop managing all
evdev devices and re-probe for devices when the application regains
focus by switching back to the tty. To facilitate this, this patch
adds clutter_evdev_release_devices() and clutter_evdev_reclaim_devices()
functions.

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.

a3bbcff946 evdev: Associate devices with the first created stage
Because evdev isn't associated with the display system, it doesn't
have any easy way to associate an input device with a stage.
Previously Clutter would never set a stage for an input device and
leave it up to the application to set it. To make it easier for
applications which just have a single fullscreen stage (which is
probably the most common use case for evdev) the device manager now
associates all input devices with the first stage that is created
unless something has already set a stage.

This updates the evdev input backend code to compile and also updates
the code to not refer to the default stage and instead check for a
stage to be associated with the input device. If no stage is currently
associated with a device generating events then the events are dropped
on the floor.

5705d08b5d evdev: don't even process events without a default stage
The evdev system is a bit different from other input systems in
Clutter because it's completly decorrelated from anything graphic.

In the case of embedded devices with no proper windowing system, you
might want to not implicitly create a default stage when you're
receiving the first input event.

This patch changes this behavior by not forwarding any event if you
don't have a default stage.

This backend is a event backend that can be enabled for EGL (for now).
It uses udev (gudev) to query input devices on a linux system, listens to

Looking at what the X11 backend does: the unicode value is being
translated to the unicode codepoint of the symbol if possible. Let's do
the same then.

Before that, key events for say KEY_Right (0xff53) had the unicode_value
set to the keysym, which meant "This key event is actually printable and
is Unicode codepoint is 0xff53", which lead to interesting results.

ef5256ec25 evdev: Factor out the xkbcommon code from the wayland client backend
The wayland client code has support for translating raw linux input
device key codes coming from the wayland compositor into key symbols

A backend directly listening to linux input devices (called evdev, just
like the Xorg one) could use exactly the same code for the translation,
so abstract it a bit in a separate file.
