When multiple relative motion events are received and queued, we can't
base the relative => absolute motion conversion off of the stage pointer
position, since that is only updated when the queue is processed at
the beginning of each frame. The effect of trying to use the stage
pointer position was that subsequent motion events were effectively
dropped.
To improve things, switch to keeping track of the pointer position
ourselves in the evdev backend and adding to that.
This has the side effect of making the internal function
_clutter_input_device_set_coords not effect the internal coordinate
state of the evdev stage, but AFAICS there is nothing depending on that
so that should be fine.

Pointer button events will be received from a device where a button has
been pressed, even though an equivalent button has been pressed (same
button code) on a device connected to the same seat. notify_button()
expects to only be called as if there was only one pointer device
associated with the given seat, so to achieve this, ignore every event
where forwarding it would result in multiple 'pressed' or 'released'
notifications.

Keyboard key events will be received from a device where a key has
been pressed, even though an equivalent key has been pressed (same
key code) on a device connected to the same seat. notify_key()
expects to only be called as if there was only one keyboard device
associated with the given seat, so to achieve this, ignore every event
where forwarding it would result in multiple 'pressed' or 'released'
notifications.

libinput's API changed from separate scroll events for vert/horiz scrolling to
a single event that contains both axes if they changed.
Updated by Armin K. to use the discrete axis value for wheel events as done
in Weston.

In keyboard/mouse wireless combos, it is rather common for the mouse to
claim it contains the multimedia keys, this makes libinput enable both
the pointer and keyboard capabilities on this device, and Clutter thus
to create a keyboard ClutterInputDevice for it.
Ideally clutter devices should be able to reflect their full capabilities,
or maybe account for the fact that certain events can be sent from
seemingly unexpected device types. But this will bring a somewhat better
behavior on such devices.
https://bugzilla.gnome.org/show_bug.cgi?id=740518
libinput_suspend() will trigger the removal of input devices, but also
the emission of button/key releases pairing everything that is pressed
at that moment. These events are queued, but the ClutterInputDevice
pointers in these will point to invalid memory at the time these are
processed.
Fix this by flushing the event queue, in order to ensure there are no
unprocessed input events after libinput_suspend().

xkb_state creation has been refactored out of clutter_evdev_set_keyboard_map(),
and used too in clutter_evdev_reclaim_devices(), so the xkb_state is fresh
clean after input is paused/resumed (and keyboard state possibly changed in
between)

The vector of libinput and Wayland pointer axis events are in pointer
motion coordinate space. To convert to clutter's internal representation
the vectors need to be scaled to Xi2 scroll steps.

Those are translated into CLUTTER_TOUCH_* ClutterEvents. As the
"NULL" ClutterEventSequence is special cased, the slot=0 value is
avoided.
Frame events are ignored, as there is no Clutter equivalence, and
Cancel events are sent to all current individual touches.
https://bugzilla.gnome.org/show_bug.cgi?id=728968
And ensure the core pointer shares the same stage than the slave
device when those events are set. This fixes problems on the evdev
backend where the last touch unsets the stage on the device, but
nothing sets it back afterwards.

All backends follow the same pattern of queueing events first in
ClutterMainContext, then copying them to a ClutterStage queue and
immediately free them. Instead, we can just pass ownership of events
directly to ClutterStage thus avoiding the allocation and copy in
between.

There could be times when we may not necessarily see a device appear
at initialization time, like when we're VT switched away when we
initialize, and thus we can't ever rely on a main seat appearing.
Always create a main seat with logical pointer/keyboard devices, and
tie the first physical seat that comes in to the main seat.
https://bugzilla.gnome.org/show_bug.cgi?id=726199
We're going to create the main seat at an earlier time, when
we don't have the physical libinput_seat yet, so we need to
do the association later.
https://bugzilla.gnome.org/show_bug.cgi?id=726199
ClutterInputDevice's default initial coordinates is (-1, -1) and since
they're updated from events in a relative way it means that the
pointer can go outside the stage right from the first event.
We usually let this up to higher layers to fix through the pointer
constraint callback but that doesn't work if the first event doesn't
put the pointer immediately inside the stage.
https://bugzilla.gnome.org/show_bug.cgi?id=725103
Doing so is unlikely to work reliably. Instead, switching the keymap
should be done at a time when no key is currently pressed down, but
let's leave that task to higher level code.
This allows us to remove key state tracking at yet another level in
the stack since higher level code likely already tracks this for other
purposes.

The kernel keyboard repeat functionality isn't configurable and
libinput rightfully ignores it.
This implements keyboard repeat in userspace allowing for consumers to
set the initial delay and repeat intervals.

The evdev backend has always been excluded from Clutter's API
stability guarantee though in an informal way. This commit makes it
explicit by forcing users to define CLUTTER_ENABLE_COMPOSITOR_API.
https://bugzilla.gnome.org/show_bug.cgi?id=725102
Instead of having its own evdev input device processing implementation,
make clutter's evdev backend use libinput to do input device processing
for it.
Two GObject parameters of ClutterInputDeviceEvdev (sysfs-path and
device-path) are removed as they are not used any more.
Before ClutterDeviceManagerEvdev had one virtual core keyboard and one
virtual core pointer device. These are now instead separated into seats,
which all have one virtual core keyboard and pointer device respectively.
The 'global' core keyboard and pointer device are the core keyboard and
pointer device of the first seat that is created.
A ClutterInputDeviceEvdev can, as before, both represent a real physical
device or a virtual device, but is now instead created either via
_clutter_input_device_evdev_new() for real devices, and
_clutter_input_device_new_virtual() for virtual devices.
XKB state and button state is moved to the seat structure and is thus
separated per seat. Seats are not a concept exposed outside of clutter's
evdev backend.

The added support is very very basic (single touch, motion only,
no acceleration, no pressure recognition), but anything more
complex requires a state machine that will be hopefully provided
by libinputcommon in the future.
And at least, with this patch the pointer moves, which will be
useful for people testing wayland in 3.10 without a physical mouse.

It was a bad idea to add it, because clutter events are batched,
so by the time the application processes one, the keyboard state
internally tracked by clutter could be already different.
Instead, apps should use clutter_event_get_state_full()

We can't dispatch a motion event for EV_REL (because we don't
have yet the other half of the event), but we can't also queue
them at the end of processing (because we may lose some history
or have button/keys intermixed).
Instead, we use EV_SYN, which means "one logical event was
completed", and let the winsys-independent code do the actual
motion compression.
