Introduce serialport_write_nonblock()
It seems useful to have a generic and platform-independent method to read and write to a serial port without blocking. This is the write part. This allows to get rid of the explicit temporary disabling of blocking I/O in serprog's sp_synchronize(). Corresponding to flashrom svn r1662.
