Carlos Garnacho 2a584a8f01 wayland: Make use of Wayland event grabbing mechanism 
Enable grabbing input for popups, and drag-and-drop. Since the very
switch to using ClutterGrab underneath Wayland grabs will challenge
assumptions in existing code, these had to change in one go. A notable
one is that meta_display_windows_are_interactable() is not 100% true
anymore for xdg_popups, at least not the same.

Another change happening in lockstep is MetaDnD no longer having
to funnel events to Wayland, since the grab triggered by Wayland DnD
is now a cause of "compositor grabs", and will naturally receive events
as long as it hold. while "modal".

A number of ad-hoc checks for grabbing state has also been dropped
from src/wayland/ internals, since again Wayland grabs are a reason
for Clutter grabs, plus the mechanism itself will already take care
of focus loss and restoration.

Mutter

Mutter is a Wayland display server and X11 window manager and compositor library.

When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.

When used on top of Xorg it acts as a X11 window manager and compositing manager.

It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.

Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.

Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
