At least indirectly, this is set as object qdata while the
window drag is ongoing, and reset/reconstructed if needed.
Consequently, this edge data does not need to be stored in
the MetaDisplay struct anymore.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
Even though the data is still stored in the display, add a "high
level" meta_window_drag_update_edges() call, so that the cached
edges may be updated while a window drag operation is ongoing.

Since MetaWindowDrag took a lot of this code to handle window drags
internally with less interactions with the rest of the stack, this
code in display/window/keybindings is unused.

Now that it is called from a single place, there's a few arguments
that are unnecessary:
- button and modifiers are unused
- already_grabbed was originally added to handle grab transitions between
window menus (GtkMenus, back in the day) with display grabs. It's no
longer necessary now
- frame_action can be passed through the META_GRAB_OP_WINDOW_FLAG UNCONSTRAINED
flag

Leave meta_window_begin_grab_op() as the only public API to initiate
a display grab. There's no longer grab operations that don't attain
windows, and ending these grabs usually happen through user interaction
when the right circumstances happen.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
The frame_action boolean is only used by constraints.c code, in order to
determine whether a moving window should be able to move past the top
bar or not.
We can avoid the special casing by passing this information as a
META_GRAB_OP_WINDOW_FLAG_UNCONSTRAINED flag passed with the grab op.

The API has no concept of user data, and requires the user to some how
get an instance without context, i.e. via static globals. Limit this to
the file where this is needed.

With high frequency mouse devices, we would send very many configure
events per each update cycle, which had the end result that some clients
constantly re-allocating and redrawing their buffers far too often, if
they did this in direct response to xdg_toplevel configure events.
Lets throttle the interactive resize updates to stage updates, to avoid
having these clients doing the excessive buffer reallocation.
This also removes some old legacy X11 client resize throttling, that
throttled a bit arbitrarily on 25 resizes a second; it is probably
enough to throttle on stage updates for these clients.

meta_window_(un)queue() was implemented with global arrays in window.c
that managed MetaLater handle IDs and lists of window queues. In order
to rely less on scattered static variables and making it clearer that
we're dealing with per display window management and not something
specific to a single window, move the window resize/calc-showing queue
management to MetaDisplay.

Wayland event processing and WM operations are themselves outside the
ClutterGrab loop so far. Until this is sorted out, these pieces of
event handling have got to learn to stay aside while there is a
ClutterGrab going on.
So, synchronize foci and other state when grabs come in or out, and
make it sure that Wayland event processing does not happen while
grabs happen.

MetaGravity is an enum, where the values match the X11 macros used for
gravity, with the exception that `ForgetGravity` was renamed
`META_GRAVITY_NONE` to have less of a obscure name.
The motivation for this is to rely less on libX11 data types and macros
in generic code.

This ATM completes the task right away, but we will want to do
further things here that are asynchronous in nature, so prepare
for this operation being async.
Since the X11 backend doesn't really need this, make it go on
the fast lane and open the MetaX11Display right away, the case
of mandatory Xwayland on a wayland session is now handled
separately.

What "restart" means is somewhat different between x11 and wayland
sessions. A X11 compositor may restart itself, thus having to manage
again all the client windows that were running. A wayland compositor
cannot restart itself, but might restart X11, in which case there's
possibly a number of wayland clients, plus some x11 app that is
being started.
For the latter case, the assert will break, so just make it
conditional. Also rename the function so it's more clear that it
only affects X11 windows.

This is a simple clipboard manager implementation on top of MetaSelection.
It will inspect the clipboard content for UTF-8 text and image data whenever
any other selection source claims ownership, and claim it for itself
whenever the clipboard goes unowned.
The stored text has a maximum size of 4MB and images 200MB, to prevent the
compositor from allocating indefinite amounts of memory.
This is not quite a X11 clipboard manager, but also works there.

Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

This is a simple libcanberra abstraction object, so we are able
to play file/theme sounds without poking into GTK+/X11. Play
requests are delegated to a separate thread, so we don't block
UI on cards that are slow to wake up from power saving.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
