* fhandler_serial.cc (fhandler_serial::open): Avoid extraneous setting of res.
* termios.cc (tcsetattr): Correctly record errno after tcsetattr call.
* fhandler_serial.cc (fhandler_serial::tcsetattr): Add error-checking so that
if any Win32 SetComm*() calls fail, errno gets set to EINVAL and tcsetattr()
returns -1. Catch invalid bitrates, mostly. If baud rate setting is B0, just
drop DTR and leave Win32 DCB bitrate as-is since 0 is not a valid Win32
setting.
(fhandler_serial::tcgetattr): If DTR is low, populate the bitrate as B0,
otherwise get it from the DCB.
