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.
