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.
https://bugzilla.gnome.org/show_bug.cgi?id=771305
Add a new object class, MetaWaylandInputDevice, and make all device
classes (pointer, keyboard, touch) inherit it. In the future common
functionality may be placed there.

This will be useful during DnD, where mutter is expected to consume
keyboard events for either allowing changes in the selected DnD action,
or misc a11y features like keyboard-driven DnD.
Currently, the vtable contains 2 functions, key() will be used on every
key event we get from Clutter, modifiers() will notify of changes in the
keyboard modifiers (mouse buttons will never be set in the modifier mask)
https://bugzilla.gnome.org/show_bug.cgi?id=760805
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.

If the user Alt-Tabs out of the window, we will be left thinking
the Alt key is still pressed since we don't see a release for it.
Solve this and other related issues for the nested X11 compositor
by selecting for KeymapStateMask which causes a KeymapNotify event
to be sent after each FocusIn, and when we get these events, update
the internal XKB state and send any necessary modifiers events to
clients.
https://bugzilla.gnome.org/show_bug.cgi?id=753948
The key event should be interpreted by clients with the modifier state
as it was before the event itself just as in X11 input events.
Achieving this in wayland is a matter of sending the key event first
and the modifiers after (if needed).
This isn't really specified in the wayland protocol but it matches
weston's behavior and should avoid corner cases in clients.
https://bugzilla.gnome.org/show_bug.cgi?id=738238
We never want to send pressed keys to wayland clients on enter. The
protocol says that we should send them, presumably so that clients can
trigger their own key repeat routine in case they are given focus and
a key is physically pressed.
Unfortunately this causes some clients, in particular Xwayland, to
register key events that they really shouldn't handle, e.g. on an
Alt+Tab keybinding, where Alt is released before Tab, clients would
see Tab being pressed on enter followed by a key release event for
Tab, meaning that Tab would be processed by the client when it really
shouldn't.
Since the use case for the pressed keys array on enter seems weak to
us, we'll just fake that there are no pressed keys instead which
should be spec compliant even if it might not be true.

Sophisticated clients, like those using ClutterGtk, will have more
than one focused resource per client, as both Clutter and GDK will
ask for a wl_pointer / wl_keyboard. Support this naturally using
the same "hack" as Weston: multiple resource lists, where we move
elements from one to the other.
In order to support multiple pointers for the same client, we're
going to need to kill it.
This will cause crashes for now, but will be fixed by the next
commit.
In particular we need to know about all key events to keep the xkb
state reliable even if the event is then consumed by a global shortcut
or grab and never reaches any wayland client.
We also need to keep track of all pressed keys at all times so that we
can send an updated set or pressed keys to the focused client when a
grab ends.
https://bugzilla.gnome.org/show_bug.cgi?id=722847
Any given clutter event carries the modifier state as it was before it
occured but, for the wayland modifiers event, we want the state
including the current event.
To fix this, we'll keep our xkb_state instance around instead of the
serialized mods.
https://bugzilla.gnome.org/show_bug.cgi?id=722847
Both the pointer/keyboard resource and surface resource can be destroyed
at any point in the destruction process, so we need to have destroy
listeners on both. To make the code easier to follow, rename ->focus
to ->focus_surface at the same time, and rearrange the code so that
the two of them are always grouped together.
When X clients change the keyboard map, the also update a property
on the root window. We can notice that and rebuild our data structures
with the new values, as well as inform the wayland clients.
This is a terrible hack, and it's not how we want to implement things
in 3.12, but it's enough to have the same keyboard layout in the
shell, in X clients and in wayland clients in 3.10, until we decide
on the fate of the keyboard g-s-d plugin.
https://bugzilla.gnome.org/show_bug.cgi?id=707446
We can't rely on clutter's xkb_state, because that's updated
when events are pulled from the kernel, not when we see them.
Instead, use the new clutter API to get the full modifier state
from the event (which, as a side effect, also works when clutter
is using the X11 backend for running nested).
https://bugzilla.gnome.org/show_bug.cgi?id=706963
Calling XIGrabDevice has no effect under wayland, because the
xserver is getting events from us. Instead, we need to use our
own interfaces for grabs.
At the same time, we can simplify the public API, as plugins
should always listen for events using clutter.
https://bugzilla.gnome.org/show_bug.cgi?id=705917
We need to track the full xkb_state to have the necessary information
to send to the clients, otherwise they may get confused and lock
or invert the modifiers. In the evdev backend, we just retrieve the
same state object that clutter is using, while in the other backends
we fake the state using what clutter is providing (which is a subset
of what X11 provides, which would be necessary to have full state)

This copies the basic input support from the Clayland demo compositor.
It adds a basic wl_seat implementation which can convert Clutter mouse
events to Wayland events. For this to work all of the wayland surface
actors need to be made reactive.
The wayland keyboard input focus surface is updated whenever Mutter
sees a FocusIn event so that it will stay in synch with whatever
surface Mutter wants as the focus. Wayland surfaces don't get this
event so for now it will just give them focus whenever they are
clicked as a hack to test the code.
