This changes how asynchronous window configuration works. Prior to this commit, it worked by MetaWindowWayland remembering the last configuration it sent, then when the Wayland client got back to it, it tried to figure out whether it was a acknowledgment of the configuration or not, and finish the move. This failed if the client had acknowledged a configuration older than the last one sent, and it had hacks to somewhat deal with wl_shell's lack of configuration serial numbers. This commits scraps that and makes the MetaWindowWayland take ownership of sent configurations, including generating serial numbers. The wl_shell implementation is changed to emulate serial numbers (assuming each commit acknowledges the last sent configure event). Each configuration sent to the client is kept around until the client one. At this point, the position used for that particular configuration is used when applying the acknowledged state, meaning cases where we have already sent a new configuration when the client acknowledges a previous one, we'll still use the correct position for the window. https://gitlab.gnome.org/GNOME/mutter/merge_requests/907
