        When multiple interrupts were pending, e.g. TX buffer empty and RX

        a TX interrupt before it had been sent to the processor, thus
        dropping the interrupt permanently.

        * peripheral/16450.c:



        There was a bug in the simulator's UART implementation that caused
        the UART's LSR register to become corrupted.  This was due to an
        assumption that 'char' is an unsigned type, but that is not true on
        all platforms.

        When the char type is signed and a character is read in the range
        0x80-0xff, the high bit is sign-extended into the upper bits of an
        entry in the receive FIFO.  When the character reaches the head of
        the FIFO, the upper bits of the FIFO entry are OR'ed into the LSR,
        causing the LSR to be set to 0xFF.

        A simple cast fixes the problem.
