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.

As with the Wayland display name, to avoid clashes with already an
running Xwayland or Xorg instance, override the X11 display name to
something less likely to cause a clash.

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.
Instead of scheduling a meta_later, keep track of the unassociated
windows, and look for matches as soon as the MetaWaylandSurface is
created on our side.
This will ensure the surface is given the Xwayland role before receiving
the first wl_surface.commit.
Add a new client message "_XWAYLAND_MAY_GRAB_KEYBOARD" that X11 clients
can use to tell mutter this is a well behaving X11 client so it may
grant the keyboard grabs when requested.
An X11 client wishing to be granted Xwayland grabs by gnome-shell/mutter
must send a ClientMessage to the root window with:
- message_type set to "_XWAYLAND_MAY_GRAB_KEYBOARD"
- window set to the xid of the window on which the grab is to be issued
- data.l[0] to a non-zero value
Note: Sending this client message when running a plain native X11
environment would have no effect.

We don't have any way of knowing what the intended size of a XWayland
cursor is supposed to be, so lets do what we do with regular XWayland
surfaces and don't scale them. The result is that cursor sprites of
HiDPI aware X11 clients will show correctly, but non-aware clients may
have tiny cursor sprites.
