A client request for maximizing itself should always be handled by mutter
by emitting a configure event with the native maximized resolution,
regardless of the client's own set limits. This also aligns the behavior by
allowing fixed-sized windows to go into fullscreen or maximized state.

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.

This is more in line with the protocol, and allows us to remove some
awkward code that tries to "combine" different metadata from different
monitors into one, which sometimes meant picking an arbitrary "main"
monitor, or "and" metadata together to find a common ground.

Before we first created the MetaWaylandCompositor instance, which would
repare Clutter/Cogl so they could initialize and turn on Wayland display
server features, then later to initialize the rest. Now that part is
done by the Wayland infrastructure itself, so we don't need the early
initialization. Simplify things a bit by centralizing it all into a
single meta_wayland_compositor_new() call.

As with the compositor type enum, also have the X11 display policy enum,
as it's also effectively part of the context configuration. But as with
the compositor type, move it to a header file for enums only, and since
this is a private one, create a private variant meta-enums.h.

The DRM buffers aren't really tied to mode setting, so they shouldn't
need to have an associated mode setting device. Now that we have a
device file level object that can fill this role, port over
MetaDrmBuffer and friends away from MetaKmsDevice to MetaDeviceFile.

When the MetaWindow resize machinery for toplevels ended up in the
Wayland window implementation, we tried to avoid configuring
not-yet-mapped windows that just had its zero sized dimension pass
through the constraint machinery, resulting in a 1x1 sized window.
If we'd properly set up the min size metadata earlier, that 1x1 would
likely be the minimum size set of a window, which makes things harder to
predict when peeking at side effects.
However, what the side effect peeking intends to do, as documented in
the comment, was to figure out when the client hadn't committed any
buffer yet, i.e. during the initial map, and in those cases avoid
sending that nasty 1x1 size, resulting in silly window sizes. A more
robust way to detect this is instead checking when we shouldn't really
try resize things our own way, and in those cases early out as was done
before.
This means that, for a yet to me mapped window, we only ever want to
send an initial non-zero configuration when 1) it's initially maximized,
2) initially fullscreen, or 3) initially tiled in any way, as those are
the situations where the compositor is the one deciding the size.

The cancel phase for swipe gestures was not being handled, hence,
Wayland "end" events where not sent to clients when the gesture was
cancelled.
A swipe gesture is cancelled when extra finger(s) are put down on the
touchpad in the middle of the gesture or when some, but not all, of the
fingers are put up.

Getting crossing events is necessary between client surfaces while
there is a popup grab in effect (e.g. allow press-drag-release in
menus), we should only stick with the focus surface while the pointer
is outside any client surface.
This partially undoes commit 79050004b0 (or, at least, mutter no
longer fixes the bug it claimed to fix). This will be addressed in
gtk4.

We first initialized the Wayland infrastructure, then the display, but
on shutdown, we first teared down the Wayland infrastructure, then the
display.
Make things a bit more symmetric and tear down the display before
Wayland. This however means we need to tear down some things Wayland a
bit earlier than the rest. For now this is a separate function, but
eventually, it can be replaced with a signal shared by the backend's
'prepare-shutdown' signal.

This way we can initialize without having any way to retrieve it via
some global variable. This isn't needed now, but will be once Wayland
infrastructure initializiation is done in a single step.

This is especially important as we might end up here when initializing
the Wayland infrastructure. Later that will be done in one step, meaning
the "get_default()" function will not work properly.

It might not be there when shutting down, so get it from a more managed
place. Note that this isn't strictly needed right now, but eventually,
the MetaWaylandCompositor pointer will be cleared using a g_clear*()
helper, which clears the pointer before freeing the instance, which
wouldn't work here.

This will allow us less awkward startup, where previously we had to
pre-initialize Wayland very early so Cogl could bind the Wayland display
when it initialized. Move things around so we bind the Wayland EGL
display when initializing the rest of Wayland infrastructure.

The callback on_displayfd_ready() would unconditionally set the return
value to TRUE, regardless of the condition.
Use the GIO condition to determine if there was data written and adjust
the return value accordingly.

We initialize, but might not start, e.g. when a test case just needs a
backend and doesn't start mutter. When cleaning up, we'll still try to
clean up Xwayland integration, and this commit handles cleaning up
without having made the mess.

We make objects inert when disabling the seat, but we requests may still
have effect. This is especially bad if disabling is followed by
destroying, but also means e.g. set_cursor() not doing an early out
after the pointer capability was disabled.

MetaDisplay does a lot of things, and is a central part to anything
window management. To let Wayland units have an easier time tearing
down, make it so that the Wayland infrastructure is terminated before
MetaDisplay.
This also makes sure that X11 support is turned off, so that we don't
stumble upon Xwayland terminating due to the Wayland socket connection
being broken. Will mitigate that in a better way in a later commit.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1822>
We might not be the only entity holding on to the X11 GdkDisplay,
meaning the X11 connection will stay alive indefinitely, e.g. if the gjs
context has some reference to it.
Avoid running into issues due to X11 connection errors by setting the
libX11 handlers to no-ops, so when we are terminating; that means the
GDK X11 connection can stay "alive" until its too late, and we'll just
silently ignore any connection errors that may happen due to the
lingering GDK display reference.

Compositor behaviour when calling `wl_data_device_manager_get_data_device`
for the same seat multiple times is not very clearly defined in
the spec and both Mutter and Weston currently don't handle
the DnD case properly.
While Weston handles DnD only for the last created data device,
Mutter, because of some internal reshuffling, ends up toggling
between two devices.
Properly handling this case requires some bigger changes. So
in order to behave predictable and in line with Weston,
only take the last created data device into account while
still keeping the previous created ones around.
The main affect client here is Firefox, which gets very
confused by the toggling behaviour and becomes more stable
with this patch.

If a subsurface first gets reordered and afterwards detached from
the parent before the parent surface got commited, we currently
would end up reattaching the subsurface to its previous parent.
While clients should avoid this behaviour, it's legit according
to the spec.
We already prevent similar cases where the subsurface is destroyed -
extend that check to detaching, which includes the destroy case.
