commit 9f9c5365816bdd036fd80d54b22e86764ea4b7a7

    Add XSetIOErrorExitHandler() function
    
    This function complements XSetIOErrorHandler(), allowing to override
    the default behavior that trusts on I/O errors never coming back
    (i.e. exit()ing the process).
    
    This is meant as a mechanism for Wayland compositors (that are too
    a X11 client + compositing manager) to unfasten seatbelts and jump
    through the car window. It might get lucky and land on a stack of
    pillows.
    
    In consequence, some functions labeled as _X_NORETURN can as a
    matter of fact return. So those hints were removed.

    Prepare for _XIOError() possibly returning
    
    Ensure current state is cut short on _XIOError(), possible reentrancy
    should be skipped through the XlibDisplayIOError flag checks.
