Add SocketCAN support (#1228)

Browse Source 
* Add SocketCAN support

A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other's applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but it can also be used in many other contexts. For each device, the data in a frame is transmitted sequentially but in such a way that if more than one device transmits at the same time, the highest priority device can continue while the others back off. Frames are received by all devices, including by the transmitting device.

* Update also for GS_USB support

There is a port of the candleLight USB to CAN firmware for CANable. The port works very well under Linux using the gs_usb driver. This firmware does not use slcan, so it is not interchangeable with the stock firmware. However, the CANable appears as a CAN interface natively in Linux

With the candlelight firmware, simply plug in the CANable and the device will enumerate as can0. Set the baud rate and bring the interface up with the following command, and you're good to go!

ip link set can0 up type can bitrate 500000
