Add an "UnknownSignal" value for the pinout signals
This needs to be added to the API because there are situations where the serial
line state is unknown. The two typical use cases are:
1) The syscall cannot retrieve the state for some reason.
2) The serial port is not open.
This has been (only build!) tested on Linux (Arch) with Qt 4 and then 5.
