x11: Integrate frames client into Mutter
Replace the in-process implementation of frames with the external
frames client.
When a client window is created and managed by Mutter, Mutter will
determine whether it is a window that requires decorations and
hint the creation of a frame for it by setting the _MUTTER_NEEDS_FRAME
property on the client window.
After the frames client created a window that has the _MUTTER_FRAME_FOR
property, Mutter will proceed to reparent the client window on the
frame window, and show them as a single unit.
Rendering and event handling on the frame window will be performed by
the external client, Mutter is still responsible for everything else,
namely resizing client and frame window in synchronization, and
managing updates on the MetaWindowActor.
In order to let the frame be managed by the external client, Mutter
needs to change the way some properties are forwarded to the client
and/or frame windows. Some properties are necessary to keep propagating
to the client window only, some others need to happen on the frame
window now, and some others needs to be propagated on both so they
are synchronized about the behavior.
Also, some events that were previously totally unexpected in frame
windows are now susceptible to happen, so must be allowed now.
MetaFrame in src/core/frame.c now acts as the wrapper of foreign
windows created by the frames client, from the Mutter side.
