Linux: Serial minor update (#1053)

- The symlink name for the PTY device is set using --my-serial-port
  making --my-serial-pty deprecated
- Replace MY_LINUX_IS_SERIAL_PTY with MY_LINUX_SERIAL_IS_PTY
- MY_DEBUGDEVICE can be used to print debug messages from MySensors
  (as it is currently in the other architectures)
- Rename SerialSimulator class to StdInOutStream
- Remove old deprecated option --my-radio

+ * The MySensors Arduino library handles the wireless radio link and protocol
+ * between your home built sensors/actuators and HA controller of choice.
+ * The sensors forms a self healing radio network with optional repeaters. Each
+ * repeater and gateway builds a routing tables in EEPROM which keeps track of the
+ * network topology allowing messages to be routed to nodes.
