    Change serial_send_break and serial_write to throw

    This changes serial_send_break and serial_write to throw exceptions
    rather than attempt to set errno and return an error indicator.  This
    lets us correctly report failures on Windows.

    Both functions had to be converted in a single patch because one
    implementation of send_break works via write.

    This also introduces remote_serial_send_break to handle error checking
    when attempting to send a break.  This was previously ignored.
