History
Dr. David Alan Gilbert 76b004d10d serial: Open non-block 
On a real serial device, the open can block if the handshake
lines are in a particular state.  If a QEMU is passing the serial
device to the guest, the QEMU startup is blocked opening the device
(with a symptom seen as a timeout from libvirt).

Open the serial port with O_NONBLOCK.
