Streams are generally recoverable by the client and errors may happen
e.g. on negotiation failures. Right now we close the stream and
corresponding session, which is neither necessary nor expected by
clients.
Just disable the stream instead and let clients handle things as they
seem fit. This allows clients to e.g. try several Gstreamer pipelines
with limited caps on a single stream.

Doing it in dispose means the backend is actively tearing down itself,
meaning various components might or might not be there, depending on how
the tearing down is implemented. Make things a bit more robust by doing
any work that might rely on the backend being there before shutdown is
done in response to the 'prepare-shutdown' signal being emitted by the
backend.

Meson enforces a separate build dir, so we no longer have to care
about build artifects in the source tree. Same applies for all
the generated crap autotools like to spread around.

Reading upon the history of this code branch (commits 6891ce95dc
and 7a4c808e43 are most relevant), it seems this code is meant to
synchronize Mutter focus state taking the Xserver state as true.
That is, if Mutter tried to change the focus but something truncated
that action, Mutter focus will be changed to be in sync with the
Xserver again.
This sounds backwards in a Wayland session. Mutter focus should be
the canonical source, and not second-guessed from the current Xserver
focus window. These race conditions might still apply between X11
clients, so make these paths only apply in that case.
An example of this breaking can be reproduced with a Spotify and
Firefox window, moving the focus from the first to the second by
going to the GNOME Shell overview in between, and clicking the
Firefox window from there. The Firefox window will be raised, but
refuse to take focus.
It's unclear what made this an issue recently, perhaps commit
0e6395d932 since the now possibly ignored XI_FocusIn/Out events
affect this accounting of the Xserver focused window. Anyhow it
sounds better to ignore these paths for Wayland/native altogether.

The intention when the offset request was added to protocol was
that the attach request in a new enough protocol version should
require dx/dy to be zero, but ignore them otherwise.
The current code checks for 0, but then overwrites the existing
dx/dy with it, which renders an earlier wl_surface_offset() call
ineffective.

This protocol is intended to let special clients create transient-for
relationships between X11 and Wayland windows. The client that needs
this is xdg-desktop-portal-gnome, which will create e.g. file chooser
Wayland dialogs that should be mapped on top of X11 windows.

When modal dialogs are attached, and we set the parent/transient-for
after setting the modal type, the attachedness isn't updated. This is
(apparently) not the case for X11 windows, as they go through a
unmanage/manage dance avoiding the issue.

The script is a list of newline separated command lines that are sent to
the client one by one as if one would have used e.g.
meta_test_client_do().
It doesn't have error handling as it's expected to be used from tests,
and handling errors in tests that never expects to handle errors is
cumbersome.

The service channel D-Bus interface aims to be a "back door" for
services that needs special casing in Mutter, e.g. have custom private
protocols only meant to be used by that particular service.
There are currently no special casing implemented; only the basic
service channel infrastructure is added. There is a single method on the
interface, that is meant to eventually be used by
xdg-desktop-portal-gnome to open a Wayland connection with a private
protocol needed for the portal backend's rather special window
management needs.
The service channel Wayland client works by allowing one instance of
each "type", where each time needs to be defined to work in parallel. If
a new service client connects, the old one will be disconnected.
MetaWaylandClient's are used to manage the service clients, and are
assigned the service client type.

One can add a wl_global filter to a wl_display instance, which can be
used to decide what clients should see what globals. This has so far
been used to limit a Xwayland specific protocol extension to only
Xwayland. In order to expand the logic about what globals are filtered
to what clients, introduce a filter manager and port the Xwayland
specific protocol filter to this new manager.
Tests are added, using a new dummy protocol, to ensure that filtering is
working as expected.

It only tests indirect clients, i.e. not the subprocess part, so far,
but tests explicitly terminating by destroying the MetaWaylandClient
object, as well as the client self terminating and the signal being
emitted.

This API creates a "client" then later sets up a wl_client and returns a
file descriptor some Wayland client can connect to. It's meant to be
used as a method other than WAYLAND_SOCKET and process launching, e.g.
passing a file descriptor via a D-Bus API.

There will be two kind of client instances, lets move fields that are
only relevant to the current way of operation in an anonymous struct to

On X11, the stage itself is backed by an XWindow, and moving the
input focus elsewhere will bypass any Clutter-level grabs.
This effectively allows newly opened windows to steal the focus
from gnome-shell itself, which is clearly undesirable. To prevent
that, only allow moving the X11 focus to a Window when no grab is
in place, just like commit 50e89e376 did for the stage focus.
But particularly the updating of x11_display->focus_xwindow is not
prevented. Since it's more consistent to the MetaDisplay/MetaX11Display
dual focus tracking and across Wayland/X11 backends, ensure the X11
input focus is actually set on the last focus Window after the
grabs are gone and windows became interactable again.

This patch unfortunately results in situations where it is intended
that the focus change happens while a grab is present (e.g. Alt+tab
popup), resulting in confused focus state.
This commit is reverted in order to try a similar approach at a
different level.
This reverts commit 7531669b4f.

We used it to retrieve a Display, and convert between Atoms and
strings. We can just use the MetaX11Display's Display (It's the
same than GDK's anyways) and use XInternAtom/XGetAtomName for
these conversions.

We didn't always set an implementation, when the foreign toplevel wasn't
found, and when the importer tried to set the parent-child relationship,
the implementation was missing and we'd crash in wl_closure_invoke() in
libwayland-server.

Windows that are decorated may get configure requests before
the frames client created a corresponding frame window and Mutter
reparented the window.
Since the configure request results in the buffer size being
used to update the window size and the window does not have a
buffer yet, these requests could mistakenly result in the client
window being given a minimal size.
In these situations, do not use the buffer size but the given
size. The window still has to undergo frame creation and
reparenting before being shown for the first time.

This used to be implicitly done by popups using a META_GRAB_OP_WAYLAND_POPUP
MetaDisplay grab. Since commit a8cd488c6f Wayland popups no longer do that,
so the keyboard focus was simply unset if a popup was destroyed while having
the keyboard focus.
Trigger a full input focus sync, so the correct MetaWaylandKeyboard focus
surface is looked up from the focused MetaWindow.

On one hand, this used to be handled generically in all the paths that
changed the MetaWaylandPointer focus surface, induced by user interaction
or not.
On the other hand, just listening for crossing events is not sufficient
since those also do happen programmatically. We must only listen to
crossing events that have a physical source device, meaning this was
created through user interaction.
