On Wayland, xdg-foreign would leave a modal dialog managed even after
the imported surface is destroyed.
This is sub-optimal and this breaks the atomic relationship one would
expect between the parent and its modal dialog.
Make sure we unmanage the dialog if transient_for is unset even for
Wayland native windows.

A window placed using a placement rule should keep that relative
position even if the parent window moves, as the position tied to the
parent window, not to the stage. Thus, if the parent window moves, the
child window should move with it.
In the implementation in this commit, the constraints engine is not
used when repositioning the children; the window is simply positioned
according to the effective placement rule that was derived from the
initial constraining, as the a xdg_popup at the moment cannot move
(relative its parent) after being mapped.

Commit a3da4b8d5b changed updating of
window monitors to always use take affect when it was done from a
non-user operation. This could cause feed back loops when a non-user
driven operation would trigger the changing of a monitor, which itself
would trigger changing of the monitor again due to a window scale
change.
The reason for the change, was that when the window monitor changed due
to a hot plug, if it didn't actually change, eventually the window
monitor pointer would be pointing to freed memory.
Instead of force updating the monitor on all non-user operations, just
do it on hot plugs. This allows for the feedback loop preventing logic
to still do what its supposed to do, without risking dangling pointers
on hot plugs.

The bool determines whether the call was directly from a user operation
or not. To add more state into the call without having to add more
boolenas, change the boolean to a flag (so far with 'none' and 'user-op'
as possible values). No functional changes were made.

The function is intentionally provided as macro to not require a
cast. Recently the macro was improved to check that the passed in
pointer matches the free function, so the cast to GDestroyNotify
is now even harmful.

Since commit b3b9d9e16 we no longer have to pass the unmanaging window
to make sure we don't try to focus it again, however the parameter also
influences the focus policy by giving ancestors preference over the normal
stack order.
https://gitlab.gnome.org/GNOME/mutter/issues/15
We refuse to move focus while a grab operation is in place. While this
generally makes sense, there's no reason why the window that owns the
grab shouldn't be given the regular input focus as well - we pretty
much assume that the grab window is also the focus window anyway.
In fact there's a strong reason for allowing the focus change here:
If the grab window isn't the focus window, it probably has a modal
transient that is focused instead, and a likely reason for the focus
request is that the transient is being unmanaged and we must move
the focus elsewhere.

Previously we relied on the test-client to make sure that a window was
shown. For X11, we did not need to do anything, but for Wayland we had
to make sure we had drawn the first frame, otherwise mutter wouldn't
have a buffer making the window not showable.
Doing it this way doesn't work anymore however, since the 'after-paint'
event will be emitted even if we didn't actually paint anything. This is
the case with current Gtk under Wayland, where we won't draw until the
compositor has configured the surface. In effect, this mean we'll get a
dummy after-paint emission before the first frame is actually painted.
Instead, move the verification that a "show" command has completed by
having the test-runner wait for a "shown" signal on the window, which is
emitted in the end of meta_window_show(). This requires an additional
call to gdk_display_sync() in the test-client after creating the window,
to make sure that the window creation vents has been received in the
compositor.
As of "stack-tracker: Keep override redirect windows on top"
(e3d5bc077d), we always sorted all
override redirect on top of regular windows, as so is expected by
regular override redirect windows. This had an unwanted consequence,
however, which is that we should still not sort such override redirect
windows on top if they are behind the guard window, as that'd result in
windows hidden behind it now getting restacked anyway.
Fix this by only sorting the override redirect windows that are found
above the guard window on top. This fixes the override-redirect stacking
test.
xdg-foreign clears the `transient_for` of a modal dialog when its
imported parent is destroyed, which would later cause a crash in
`constrain_modal_dialog()` because the transient `NULL`.
So in case a modal dialog has no parent, do not try to constrain it
against its parent.

MetaDisplay still had workspace signals, but nothing emitted them,
meaning we wouldn't get warnings if handlers were added there instead
of to MetaWorkspaceManager.

If we wait with opening the X11 window decoration GDK connection, we
might end up with a terminated X11 server before we finish
initializing, depending on the things happening after spawning Xwayland
and before opening the MetaX11Dispaly. In gnome-shell, this involves
e.g. creating a couple of temporary X11 connections, and on disconnect,
if they happen to be the last client, the X server will terminate
itself.

Under Xorg the cursor size preference was pre-scaled originating from
gtk, while with Wayland it came directly from GSettings remaining
unscaled. Under Xwayland this caused the X11 display code to set the
wrong size with HiDPI configurations, which was often later overridden
by the equivalent code in gtk, but not always.
Fix this by always having the cursor size preference unscaled, scaling
the size correctly where it's used, depending on how it's used.

GTK+ won't be initialized if X11 is not available
Instead, when setting gtk-shell-shows-app-menu,
meta_prefs_set_show_fallback_app_menu should be
called as well.

Allow removing a prefs handler that was already removed. This allows us
to remove prefs from the dispose function without having to keep track
of it in every place.

Split X11 specific parts into MetaX11Display. This also required
changing MetaScreen to stop listening to any signals by itself, but
instead relying on MetaDisplay forwarding them. This was to ensure the
ordering. MetaDisplay listens to both the internal and external
monitors-changed signal so that it can pass the external one via the
redundant MetaDisplay(prev MetaScreen)::monitors-changed.

They are X11 specific functions, used for X11 code. They have been
