* Move update notification related functions to new display.c: Not
related to `rdp.c`.
* Rename `rdp_write_monitor_layout_pdu` to `display_write_monitor_layout_pdu`.
* Add internal `display_convert_rdp_monitor_to_monitor_def` instead of
doing the conversion inside `display_write_monitor_layout_pdu`.
