Handle possible new line in device name

[XMadFoX]

I did helper function to replace all (or most) special characters which can cause new line in device name Not sure about structure, maybe util.c should be moved to /common or /utils directory

I'm not sure if device_name even used somewhere in GUI 🤔

It's not used in GUI.

I think maybe it's better to escape \n to things like \\n, so it's still the same char in json.

And maybe just move the function into main.c, we don't use it anywhere.

Or just simply remove device_name from JSON.

@AlynxZhou and do you plan to use it in GUI?

If not, well... yeah, I think it should be just removed.
