  * Porting notes:
  * org_kde_kwin_idle refers to an early specific idle timeout protocol
  * the version ext_idle refers to an upstream stable protocol
  *
  * Pragmattically they're both the same, but we have to have two implementations for a while
  *
  * When a suitable amount of time passes (Plasma 5.24 being EOL) drop IdleTimeoutKwin and drop IdleManagerKwin as well as merge the abstract IdleTimeout class into the real implementation
