Values may need to be processed and parsed in custom ways; make this
possible via the property table infrastructure using a callback.
Will be used for e.g. parsing rotation and formats.

Instead of relatively verbosely going through the DRM properties finding
the properties we care about and saving their ID's, add a more
declarative way to fetch property metadata. This'll allow for fetching
more property IDs with relatively less code, which will be useful for
the atomic backend.

This contains a copy of a drmModeModeInfo, describing a mode. It also
has an unused pointer to the impl device it is associated with. It'll
later be used to get a blob ID for the mode.

Current Xwayland has marked the command line option "-listen" as
deprecated in favor of "-listenfd".
Use the pkg-config variable "have_listenfd" (if available) from Xwayland
to determine if we should use that option, to avoid a deprecation
warning when spawning Xwayland.

Mutter listens to two display connections, one for regular X11 clients
and another one for the so called "managed services".
Once an available display number is found for the regular X11 clients,
mutter would then redo the work to find another available display number
for the managed services.
Yet, it does so starting from the same initial display, which is a waste
of time since it just tried all displays to find the first available
one, so all these, including the regular display it just took, are now
in use.
So instead of starting over from the beginning when looking for a
display available for the managed services, continue from the next
display immediately after the one we found precedently.

Some X11 servers may not always create a lock file, yet mutter uses the
lock file to find a possible display number and then tries to bind to
the socket corresponding to that display number.
If it fails to bind, it will simply bail out. As a result, if an X11
server is already listening on that display but hadn't created a lock
file, mutter won't be able to start Xwayland.
To avoid that possible issue, make mutter retry with another display
for a given number of tries when binding fails even though the display
was supposed to be available based on the lock file presence.

The function choose_xdisplay() calls open_display_sockets() which calls
ensure_x11_unix_dir().
We don't need to do that from within the loop though, as the directory
/tmp/.X11-unix is the same regardless of the display number.
Move the call to ensure_x11_unix_dir() from open_display_sockets() to
choose_xdisplay() prior to enter the display loop.

In case of failure to open the display sockets, we would not propagatre
the error which can cause a crash when trying to show the error message.
Properly propagate the error to avoid the crash.

In the shutdown paths we check with the X11 display whether there's
remaining clients. However this happens in paths that happen after
the MetaX11Display vanished in the case of Xwayland crash.
Since in that situation the clients are forcibly vanishing too,
skip the client check.

This means backend implementations can have more control of the order of
how things are destroyed. To be precise, this will, in the next commit,
allow us to destroy the logind integration after the clutter backend
thus the libinput owning seat, that uses the logind integration to
release input devices.

We can't post tasks to the input thread when cleaning up the
MetaSeatImpl, as that will make the GTask complain about adding
references to a to be purged object. Avoid this by adding an explicit
meta_seat_impl_destroy() function that handles the destruction of the
MetaSeatImpl properly.
This also does more of the cleanup in the input thread, as that is where
it was managed. Will likely not make a difference as before this
happened after tearing down the thread, but lets tear down things in the
thread they were managed for good measure.
This fixes the last log spew I see right now when terminating mutter.

Closing automatically Xwayland once all relevant X11 clients are gone is
inherently racy, if a new client comes along right at the time we're
killing Xwayland.
Fixing the possible race conditions between mutter, Xwayland and the X11
clients may take some time.
Meanwhile, make that an experimental feature "autoclose-xwayland".

<super> is considered a system modifier, and applications cannot use it
for keyboard shortcuts or as button modifier. It doesn't seem too much
of a loss taking <super>+scroll-event away as well, so that it becomes
available to gnome-shell/extensions.

Currently, mutter checks for the presence of X11 windows to decide
whether or not Xwayland can be terminated, when Xwayland is started on
demand.
Unfortunately, not all X11 clients will map a window all the time, an
X11 client may keep the X11 connection opened after closing all its
windows. In that case, we may terminate Xwayland while there are some
X11 client connected still, and terminating Xwayland will also kill
those X11 clients.
To avoid that issue, check the X11 clients actually connected using the
XRes extension. The XRes extension provides the PID of the (local) X11
clients connected to the Xserver, so we need to match that against the
actual executable names, and compare with a list of known executables
that we can safely ignore, such as ibus-x11 or gsd-xsettings.
We also check against our own executable name, considering that the X11
window manager is also an X11 client connected to the Xserver.
Also, XRes returning the PID of local clients only is not a problem
considering that Xwayland does not listen to remote connections.
However, if the user spawns a client remotely on another system using
ssh tunneling (ssh -X), only clients which actually map a window will
be accounted for.

Some GSettings schemas moved from g-s-d to gsettings-desktop-schemas
in g-s-d 40.alpha. 40.alpha.1 didn't include the corresponding
adjustment, so do a quick follow-up release to not abort on startup
with the latest g-s-d release.
ClutterClickEvent currently doesn't check if button press and release
happen within the drag threshold, which can be surprising sometimes.
Only emit the "clicked" signal if the button press and release happen
within the area of drag threshold.

Changes in games between fullscreen and windowed modes may trigger
chaotic situations where the buffer and the frame size temporarily
disagree, producing rectangles with negative width/height. This is
usually followed by other updates that bring the pointer constraint
up to date.
This makes cairo panic and return an "error" empty region, which breaks
deeper down when using the region rectangles to apply the pointer
constraint.
If we hit this situation, ignore the frame rectangle, and just go with
the buffer rectangle.

We didn't tear down the libinput objects in the right thread when
exiting, but did so after the input thread exited.
We also tried to destroy the libinput devices after the libinput context
was destroyed, which isn't allowed.
Fix these two issues by tearing down the libinput objects in a input
thread task that when done exits the input thread. This effectively
"flushes" the input thread tasks while destroying the libinput objects
just before the thread exits.
While it might fine to tear down libinput objects in an arbitrary (main
in this case) thread while making sure nothing pokes at it in parallel
(e.g. the input thread is gone), libinput is by definition single
threaded, and could theoretically make assumptions about this, and we
shouldn't cause any possible surprises here, so make sure to destroy it
all in the right thread.
This fixes an abort() on exit caused by an assert about invalid object
destruction in libinput.

The "seat" usually refers to the ClutterSeat (MetaSeatNative) object,
and "seat_impl" to the MetaSeatImpl object, but there were still a few
places where this wasn't adhered to so fix those.
