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.

3e85ad6b95 build: make internal option_xkb_* symbols static
This makes the option_xkb_* symbols declared for the evdev device manager
and the wayland device manager private so we don't get symbol collisions
if both of these backends are enabled.

602a89afa8 evdev: fixes evdev build issues + don't ref default 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.

213e6e4a16 evdev: do not associate device with stage
Their might not be any stage at that time, so this avoids to create a
default one.

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.

17c89bd0a0 backend: Clean up the device manager creation
Create the device manager during the event initialization, where it
makes sense.

This allows us to get rid of the per-backend get_device_manager()
virtual function, and just store the DeviceManager pointer into the
ClutterBackend structure.

405e72f2e4 egl: First attempt at cleaning up the EGL native backend
At least, let's make it compile when built along with the other
backends. In reality, it still needs to be verified as working.

4ceb95d2ca evdev: Add a comment to revisit the GSource management with glib 2.28
With glib 2.28, we'll be able to have one GSource per device manager
with child sources for earch device. Make a note to update the code
in a few months.

bce4c87232 evdev: Don't oveflow when translating buttons to masks
An array is used to translate the button to its mask. Clutter defines
the masks for button 1 to 5 but we report BTN_LEFT..BTN_TASK ie
0x110..0x117. We need to pad the array for the translation not to access
random data for buttons between 0x115 and 0x117.

c20beabf93 evdev: Add mouse support
We know support EV_REL events comming from evdev devices. This addition
is pretty straigthforward, it adds a x,y per GSource listening to a
evdev device, updates from EL_REL (relative) events and craft new
ClutterMotionEvents. As for buttons, BTN_LEFT..BTN_TASK are translated
to ClutterButtonEvents with 1..8 as button number.

7cd6ba2828 evdev: Close the device gracefully in case of a read() error
Even with udev, the read fails before udev has a chance to signal the
change. Hence (and to handle errors gracefully anyway), let's remove the
device from the device manager in case of a read() error.

afd279dd76 evdev: Merge clutter-event-evdev.[ch] into the device manager
The device manager now fully owns the GSources corresponding to the
devices it manages. This will allow not only to remove the source when
udev signals a device removal but also handle read() errors gracefully
by removing the faulty device from the manager.

device, not legacy mousedev ones for instance. We rely on the sysfs
API/ABI guarantees and look for devices finishing by /input%d/event%d.

c6493885c3 evdev: First stab at an evdev backend
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
keyboard events from input devices and xkbcommon to translate raw key
codes into key keysyms.

This commit only supports key events, more to follow.
