    randr: Protect against XErrors getting output info
    
    Xwayland can create and destroy RR outputs as required.
    
    When Xwayland destroys an RR output, xev would receive a RRNotify event
    and try to get the output info.
    
    As the output is already destroyed, that will cause an XError which
    kills xev:
    
     | RRNotify event, serial 42, synthetic NO, window 0xc00001,
     | X Error of failed request:  BadRROutput (invalid Output parameter)
     |   Major opcode of failed request:  140 (RANDR)
     |   Minor opcode of failed request:  9 (RRGetOutputInfo)
     |   Serial number of failed request:  45
     |   Current serial number in output stream:  45
    
    Protect against potential XError when calling XRRGetOutputInfo() to
    avoid the issue.
    
    v2: XSync before setting the error handler, to catch pending errors
