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.
