First cut at polymorphic serial port implementation. Split serialPort_t into uartPort_t and serialPort_t. Calls to uartWrite() can now be replaced with calls to serialWrite(). Replacing calls to serialWriteByte(softSerial_t*, char) with calls to serialWrite(serialPort_t*, char). This completes the proof of concept for polymorphic serial port implementations (uartPort and softSerialPort). Renaming isSerialAvailable to uartTotalBytesWaiting. Renaming serialAvailable to softSerialTotalBytesWaiting. Adding serialTotalBytesWaiting to serial API and updating calls to the former methods to use the serial API. Renaming serialRead to softSerialRead. Adding serialRead to serial API and updating calls to uartRead and softSerialRead to use the serial API. Renamed uartPrint to serialPrint which now works on any serialPort implementation. Replacing calls to isUartTransmitEmpty with isSoftSerialTransmitBufferEmpty. Replacing remaing calls to uartWrite with serialWrite. Adding isSoftSerialTransmitBufferEmpty to the serial API. Adding serialSet/GetBaudRate to the serial API. Since softSerial does not implement serialSetBaudRate some GPS serial initialisation code has been updated. At this point it is probably possible to switch around all the ports and use a software serial implementation if desired.
