We'd set the capabilities to 'none', meaning all previously enabled
device classes would be disabled. That means we shouldn't re-disable
them directly after.
This ensures '..disable()' is only called once for every '..enable()'.

The way wl_seat capabilities work, by notifying clients of capabilities
changes, and clients consequently requesting the relevant interface
objects (pointer, keyboard, touch) is inherently racy.
On quick VT changes for example, capabilities on the seat will be added
and removed, and by the time the client receives the capability change
notification and requests the relevant keyboard, pointer or touch,
another VT switch might have occurred and the wl_pointer, wl_keyboard or
wl_touch already destroyed, leading to a protocol error which kills the
client.
To avoid this, create the objects when requested regardless of the
capabilities.

These are ClutterInputFocus subclasses, so this will trigger reset of
the input method. As the .done event is possibly deferred in the
zwp_text_input_v3 implementation, ensure the changes caused by the
reset are flushed immediately, before the button press is forwarded
to the client by MetaWaylandPointer.

Just because X11/XI uses a particular terminology doesn't mean we
have to use the same terms in our own API. The replacement terms
are in line with gtk@1c856a208, which seems a better precedent
for consistency.
Follow-up to commit 17417a82a5.

The clutter_input_focus_filter_key_event() function has been made
a more generic filter_event(). Besides its old role about letting
key events go through the IM, it will also process the IM events
that are possibly injected as a result.
Users have been updated to these changes.

Instead of having everything clumped at MetaWaylandDataManager,
split the primary selection to its own struct. This manager is
handled separately from wl_data_device_manager and other selection
managers, so they would be able to interoperate between them, even.

This allows xdg_popup.grab() to work with styli. Without this check
we would bail out and emit xdg_popup.popup_done, leaving stylus users
unable to interact with popup menus, comboboxes, etc...

The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
This protocol supersedes the internal gtk_text_input protocol that
was in place. Functionally it is very similar, with just some more
verbosity in both ways (text_change_cause, .done event), and some
improvements wrt the pre-edit text styling.
These paths implicitly relied on the forwarded IM key events having
a source_device backed by a real HW device. This assumption is no
longer held true since commit b5328c977.
Explicitly check the INPUT_METHOD flag so they are handled as they
should despite not being "real HW" events.
Offer the text-input interface global, so it can be used by clients. The
MetaWaylandSeat will also let MetaWaylandTextInput intercept key events
before the keyboard interface handles those.
The events might fall through if there's no corresponding active
pointer/keyboard/touch interface. Barring bugs this should be safe to do,
just a bit wasteful.
Window moving and resizing depends on the `meta_wayland_seat_get_grab_info`
function succeeding. At the moment, tablet tools do not generate implicit
grabs like the pointer and touch. This commit adds the necessary elements
to track implicit grabs and retrieve their information.

Relayouts in clutter may trigger synthesized crossing events if the
actor below the pointer changes. In that situation we do need to
repick() the MetaWaylandPointer to end up with the right current
wayland surface.

Make the device <-> seat association permanent, and move it into
MetaWaylandInputDevice. A device will never be disassociated with a
seat, so there is no point in unsetting it.

Meant to replace explicitly checking whether a
MetaWaylandPointer/MetaWaylandKeyboard/MetaWaylandTouch has a seat or
not to determine whether they are supposed to be active or not.

The seat capability updating is synchronous, but input events are
asynchronous (first queued then emitted). This means we may end up in a
situation where we from libinput first may receive a key event,
immediately followed by a device-removed event. Clutter will first
queue the key event, then remove the device, immediately triggering the
seat capability removal.
Later, when the clutter stage processes the queued events, the
previously queued key event will be processed, eventually making it
into MetaWaylandSeat. Before this patch, MetaWaylandSeat would still
forward the key event to MetaWaylandKeyboard, even though it had
'released' it. Doing this would cause referencing potentially freed
memory, such as the xkb state that was unreferenced when the seat
removed the capability.
In order to avoid processing these lingering events, for now, just drop
them on the floor if the capability has been removed.
Eventually, the event queuing etc needs to be redesigned to work better
when used in a Wayland compositor, but for now at least don't access
freed memory.

All pads will share the same focus than the keyboard, so this means that:
- The focus changes in-sync for keyboard and all pad devices, and
- Newly plugged pads will be immediately focused on that same surface
Leave these checks up to the callers, the only uses of this function
(indirect, through meta_wayland_seat_get_grab_info) are
[wl_shell|xdg]_surface.move/resize/show_window_menu.
In move/resize it makes sense to check for a button being pressed, because
we must expect a button release event. However for xdg_surface.show_window_menu
we 1) don't strictly need further events and 2) we must account for press+release
event pairs being processed at once in the compositor before the client sees
the former.
That is eg. the case of touchpad 2nd/3rd button tap emulation, multifinger
taps will emit the event pair at once, so when the client manages to request
xdg_surface.show_window_menu, it'll be too late in the compositor side, so the
request is ignored.

Right now we just check the pointer serial, so the popup will be
immediately dismissed if the client passes a serial corresponding to
another input device.
Abstract this a bit further and add a meta_wayland_seat_can_popup() call
that will check the serial all input devices. This makes it possible to
trigger menus through touch or keyboard devices.

Before commit ac448bd42b the pointer,
keyboard, and touch objects were initialized when the seat was created.
Now they're initialized later, when the clutter device manager finds and
loads them.
This commit makes sure we don't try to access those objects if they
aren't initialized.

The wayland seat event handlers get sent events that
aren't strictly interesting to them (such as events for
hardware devices the seat doesn't support and events for
virtual devices that the seat needs to ignore).
This commit makes sure all uninteresting events get ignored.
The grabbing state is now checked for both pointer/touch devices
within the seat, and the grab start coordinates returned by
meta_wayland_seat_get_grab_info().
https://bugzilla.gnome.org/show_bug.cgi?id=733631
The capability flags are determined from the device types of the slave devices
that are currently attached. This also happens whenever a device is added or
removed, so the capabilities are kept up to date, and clients know about these.
On VT switch, all slave devices are temporarily removed, so the cascade of
signals will make the seat end up with capabililities=0 while input is suspended.
https://bugzilla.gnome.org/show_bug.cgi?id=733563
Clutter touch events are translated into events being sent down
the interface resource, with the exception of FRAME/CANCEL events,
which are handled directly via an evdev event filter.
The seat now announces invariably the WL_SEAT_CAPABILITY_TOUCH
capability, this should be eventually updated as devices come and
go.
The creation of MetaWaylandTouchSurface structs is dynamic, attached
to the lifetime of first/last touch on the client surface, and only
if the surface requests the wl_touch interface. MetaWaylandTouchInfo
structs are created to track individual touches, and are locked to
a single MetaWaylandTouchSurface (the implicit grab surface) determined
on CLUTTER_TOUCH_BEGIN.
