As elsewhere, make sure objects that need to have a ownership up to the
context, and use this ownership chain to find relevant components, such
as the backend or the Wayland compositor object instance.
wayland/data-device: Hook up data devices to seats
They are tied to a seat - make that connection in struct fields too, so
that related objects can get to the context via it.
wayland: Don't get Wayland compositor via singleton getter
This means via the ownership chain or equivalent.
xwayland: Hook up manager to Wayland compositor
Same applies to the drag-n-drop struct.
xwayland: Make X11 event handling compositor instance aware
This avoids finding it via singletons in the callee.
xwayland: Don't get Wayland compositor from singleton
xwayland: Pass manager when handling dnd event
window/xwayland: Don't get Wayland compositor from singleton
xwayland/grab-keyboard: Don't get backend from singleton
xwayland: Don't get backend from singleton
wayland: Always get the backend from the context
This means traveling up the ownership chain or equivalent when
necessary.
wayland: Hook up data devices, offers and sources to the compositor
This allows tying them to a context without going through any
singletons.
wayland: Don't get display from singleton
xwayland: Don't get display from singleton
tablet: Don't get display from singleton

Back in 2014 sending pressed keys to Wayland clients caused issues,
because at least Xwayland didn't handle that gracefully, causing issues
like ghost-pressed keys. A way it was reproduced was quickly alt-tab:ing
to and from a Firefox window, which would cause the File menu bar
incorrectly appearing.
While this was reported to the Xwayland component back then, it was,
probably by mistake, assumed to be an issue in mutter, and mutter
stopped sending pressed key events on enter.
The following year, Xwayland was eventually fixed, but the work around
in mutter has been kept around until it was again noticed as an
inconsistency between compositor implementations.
Lets remove the work around, and follow the spec, again.
This reverts commit c39f18c2d4.

We are using internal API that has the benefit of checking that the
focus surface still matches, but has the drawback that it does not
check the MetaWaylandKeyboard state.
In order to fix this, look for keyboard focus and serial matches
specifically when triggering activation.

We have this as platform-dependent data in the native backend, and
a bunch of fallback code done in place in the evcode users. Stop
making this platform-dependent data, and move it to the relevant
ClutterEvents.
The fallback code for the X11 backend case is about the same, but
now it is done directly by the X11 backend.

On VT switch, the devices are removed, which means for Wayland disabling
the keyboard.
When the keyboard is disabled, the associated `xkb_state` is freed and
recreated whenever the keyboard is re-enabled when switching back to the
compositor VT.
That means the `xkb_state` for Wayland is lost whereas the same for
clutter is kept, which causes to a discrepancy with locked modifiers on
VT switch.
To avoid that issue, preserve the XKB info only to dispose it when the
keyboard is eventually finalized.

The end goal is to have all clutter backend code in src/backends. Input
is the larger chunk of it, which is now part of our specific
MutterClutterBackendNative, this extends to device manager, input devices,
tools and keymap.
This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/672
We used to have wayland-specific paths for this in src/wayland, now we
have ClutterKeymap that we can rely on in order to do state tracking,
and can do this all on src/backend domain.
This accomodates the feature in common code, so will work on both
Wayland and X11.

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.
By using the shm file when sending the keymap to all clients, we
effectively allows any client to change the keymap, as any client has
the ability to change the content of the file. Sending a read-only file
descriptor, or making the file itself read-only before unlinking, can
be worked around by the client by using chmod(2) and open(2) on
/proc/<pid>/<fd>.
Using memfd could potentially solve this issue, but as the usage of
mmap with MAP_SHARED is wide spread among clients, such a change can
not be introduced without causing wide spread compatibility issues.
So, to avoid allowing clients to interfere with each other, create a
separate shm file for each wl_keyboard resource when sending the
keymap. We could eventually do this per client, but in most cases,
there will only be one wl_keyboard resource per client anyway.

If a client maps a popup in response to a key-down event, but the
mapping doesn't occur until after the user has already released the same
button, we'd immediately dismiss the popup. This is problematic, as one
often presses and releases a key quite quickly, meaning any popup mapped
on key-down are likely to be dismissed.
Avoid this race condition by accepting serials for key down events, if
the most recent key-up event had the same keycode.

This state tracks hardware devices' state, thus shouldn't be triggered by
events that were emulated/forwarded by the IM. Those may include modifiers
and would result in xkb_state being doubly set, and possibly stuck.
https://gitlab.gnome.org/GNOME/mutter/issues/74Closes: #74
On VT switch, the xkb state layout index is lost and reset to the first
group, so if the first layout is not the last one being used, the xkb
state used in both meta-wayland-keyboard.c and clutter/evdev will be
desynchronized with the keyboard source indicator in the gnome-shell UI.
Save the effective layout chosen along with the seat so it can be
restored when reclaiming devices.
Use the saved layout index from the clutter/evdev's seat to restore the
layout in meta-wayland-keyboard, so that switching VT doesn't reset the
layout and causes further discrepancies with the layout indicator in the
gnome-shell UI.
https://bugzilla.gnome.org/show_bug.cgi?id=791383
MetaWaylandKeyboard maintains its own xkb_state used to update Wayland
clients.
Add the necessary hooks to make sure the sticky keys modifier masks set
in clutter-evdev are also applied in MetaWaylandKeyboard's xkb_state so
that Wayland clients also benefit from sticky keys.
https://bugzilla.gnome.org/show_bug.cgi?id=788564
The layout group determines what actual keyboard layout in the keymap
to use when translating modifier state and key codes to key syms.
When changing a keymap to another, the layout groups has no relation to
the layout groups in the old keymap, thus there is no reason to
transfer it to the new state.
This fixes an issue where the xkb state in meta-wayland-keyboard.c got
desynchronized with the xkb state in clutter-device-manager-evdev.c.

Make the caller of focus setting and grab starting check whether there
is a keyboard to update the focus state or start grabbing. It makes it
more obvious what to expect, as the call would be a no-op in when no
keyboard is present.

The variable name 'l' usually refers to a GList iterator, but here it's
just a short hand for a specific list. Stop using this shorthand, since
it just makes it harder to read what list is used.

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.

If we get a key event but still have pending modifier state changes we
need to send a modifiers event right away so that the key event can be
interpreted by clients correctly modified.
This case could happen when mutter/gnome-shell itself consumes the
modifier key press event such as with the overview key which by
default is triggered on super press.
https://bugzilla.gnome.org/show_bug.cgi?id=748526
The wayland protocol has enough space to send both virtual and real
modifiers on modifiers events which saves clients the work of
resolving virtual modifiers themselves.

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)
