signal_callback_t is already deprecated, and up to now we have had to fix numerous bugs due to forgetting to disconnect it.

signal_connection_t is the new signal connection mechanism which uses destructors to automatically disconnect. It is already used in new code. So we should just go through all places where signal_callback_t is used, replace it with signal_connection_t` and then remov

This is a very simple shell protocol only allowing for fullscreen surfaces. You can find a very basic implementation here: https://github.com/swaywm/wlroots/blob/master/examples/fullscreen-shell.c

• commands to move a window up and down the stack
• commands to spawn a window in a location next or previous to the currently focused window in the stack where the window to spawn is given as an argument.
