    Xtranssock.c: avoid buffer overrun in SocketReopen
    
    This function was constructing an address from a port string allocating
    a buffer according to the size of the string but then later copying
    the address according to sizeof(struct sockaddr).
    
    This patch ensures that we allocate a struct sockaddr buffer with enough
    space for the port string to be copied into sa_data[] and uses that
    combined length to determine how much should be copied at the end of the
    function.
    
    This fixes a crash when using xwayland which uses ListenOnOpenFD() that
    will call _XSERVTransReopenCOTSServer() with a short port string like
    ":1".
