This adds the actual input capturing rerouting that takes events and
first hands them to the input capture session, would it be active.
Events are right now not actually processed in any way, but will
eventually be passed to a libei client using libeis.
A key binding for allowing cancelling the capture session is added
(defaults to <Super><Shift>Escape) to avoid getting stuck in case the client
doesn't even terminate the session.
The added test case makes sure that the pointer moves again after
pressing the keybinding.

With window_is_terminal gone, "strict" and "smart" focus mode have no
behavioural difference. Let's broaden the scope of strict focus mode,
such that windows never automatically focus unless they are an ancestor
to the transient.

As noted in the comments of window_is_terminal, this is a hack. This
code has not been touched for the better part of a decade. App res_class
tends to differ between Wayland and X11, so it is likely that none of
these apps have been recognised as terminals under Wayland ever. Also,
there are reports that strict focus mode also does not work under X11,
likely due to changes in these terminal apps over the years resulting
in different res_class than those manually specified in here. Let's remove
this hack and change strict focus mode accordingly.

Current behavior pushes a window which receives focus to the start of
the MRU list on every workspace it is on. By focusing a sticky window
the default focus on all other workspaces changes as well. This is fine
for sticky windows explicitly marked as sticky by the user but if a
window is on a secondary output and workspaces are only on the primary
output the behavior is unexpected. Instead we want the window to be the
default focus only on the current workspace but also keep those windows
in a relative MRU order to each other on all workspaces.

This avoids use-after-free when handle_start() is called following
handle_stop() during the lifetime of the MetaProfiler. This happens
on repeated profiling sessions using Sysprof.

We need to juggle with some things here to keep key event ordering
and accounting consistent.
The keyboard internal state changes (and maybe modifier event emission)
happening through meta_wayland_seat_update() should ideally happen
from the same key events that reach the client through wl_keyboard.key,
so that wl_keyboard.modifier events are emitted in the right relative
order to other key events.
In order to fix this, we need to decide at an earlier point whether
the event will get processed through IM (and maybe be reinjected),
thus ignored in wait of IM-postprocessed events.
This means we pay less attention to whether events are first-hand
hardware events for some things and go with the event that does
eventually reach to us (hardware or IM).

Don't try to handle things by threads enabling/disabling the main trace
context on-demand, just have a clear start/stop API. For the D-Bus API,
it becomes more straight forward, and for the persistent variant too, as
it avoids having to pass garbage input when it's known that arguments
will be discarded.

Persistent profiling was started via an env var, but that's rather hard
to discover and remember without grepping; change to use a command line
argument.
The profiler is started early, even during (though late in)
configuration, but configuration should ideally be instant and pointless
to configure.

A window may become undecorated while the frame window is
frozen due to updates. In that case we would both miss a
reply for the frame window, and any other means to trigger
the window actor being thawed.
Check the frozen state after destroying the frame, so that
meta_window_x11_are_updates_frozen() may end up changing
opinion if the frame window was caught in this situation.

When the X11 display is actually XWayland there's no point to delay the
compositor selection, given that mutter itself is the compositor and
doing this may cause the first X11 client that starts not to receive the
right information (and in some cases misbehave).
Since some toolkits are not handling the compositor selection changes
properly at later times, let's make their life easier by just
initializing the selection as early as the other X11 properties, given
that in this case there's nothing to replace.

We are attempting to show windows that do not yet have a
surface/buffer, this makes GNOME Shell avoid transitions
for these windows.
Since on Wayland X11 windows are also Wayland surfaces,
this check is also valid for these, and is thus made more
generic to also cater for these windows.
Eventually, meta_window_update_visibility() is called
when the surface gets its buffer, so the window can be
neatly animated.

When selecting the default focus window, is_focusable() was not
considering the new conditions for whether a window should be shown or
hidden that were added to meta_window_should_be_showing() in 39942974.
As a result the default focus window could end up a window already
hidden or hidden once meta_window_flush_calc_showing() is called by
meta_window_focus() when focusing the default window. This would cause
meta_window_focus() to fail, which is an issue if it prevents us from
unfocusing a window when it is getting unmanaged.

With the frames client, we do no longer handle events for the
frame window inside Mutter. This means we do not get events
"for free" to handle focus on a just clicked frame window.
This results in a background window not ending up focused if
clicked on its frame.
In order to fix this, make the passive button grab extend to
the frame window if a window has one. This brings back
focus-on-click behavior, while treating windows further as
a unitary surface.

With the move away from GTK3, and the indirect dependency on GTK4
grown in the GNOME Shell side, we've indirectly gotten a small sneaky
behavioral change: The GTK4 library will, right on dlopen, get
DESKTOP_AUTOSTART_ID for itself and delete it from the environment.
This happens before our own X11 session management code is
initialized, which confuses the hell out of it, into thinking
initialization is actually shutdown, gnome-session does not follow
along with this request, which leaves GNOME Shell into a confused
startup state where it never calls SmcSaveYourselfDone() and grinds
startup to a halt until gnome-session decides to move things forward.
In order to fix this, get the DESKTOP_AUTOSTART_ID before we lend
control to GNOME Shell bits and GTK4 is possibly initialized, and
feed it directly to our X11 session manager bits.

Commit 7e9d9c7eb9 added new API to replace GTK for accelerator
parsing.
Unfortunately there is another case in gnome-shell, where we have
to get the label from the logical binding name rather than the
modifier+keysym combination.
Add another small method to cover that use case.

Normally, mutter implicitly allows a window being shown to take
focus. This is normally desired, except it steals input from
GNOME Shell self. Avoid focusing the just shown window in those
situations.

2d8fa26c8e ("core: Pass "frame action" grab operations as an
"unconstrained" grab op") changed the behaviour to treat non-grab
related window moving that has the "user action" flag set to still apply
the "constrain_titlebar_visible" constraint.
The fact that it wasn't applied before was relied upon by some
extensions. While it should arguably exist a better API that for such
extensions to use that have a bit more predictable behavior, until that
is so, restore the old semantics.

A Wayland client repeatedly requesting activation of its surface using
the xdg-activation protocol would make mutter constantly update the
cursor.
To avoid needlessly updating the cursor back and forth between busy and
default, add a timeout to delay the update.

Ensure we preserve the fast zero-copy paths in Xwayland fullscreen
windows, instead of maybe rendering the client surface on top of the
frame surface, and providing the latter to the compositor.
To achieve this, additionally synchronize frame state when
recalculating features (e.g. after fullscreen/unfullscreen), and
account for this new condition when creating or destroying frames.

These are done on the backend X11 connection, so it is unclear
what is the interplay through the borrowed global XSetErrorHandler()
that triggers issues for us here.
Anyways, better to be explicit, and use error traps the MetaBackendX11
style, in coherence with the rest of the things happening in that
display.
