File licensing issues

Background: See PR #23, this comment.
The following files are licensed under a license that prevents us using the Linux headers with them:

• read-seralno.h - LGPLv3+
• makestuff.h - LGPLv3+
• debug.h - LGPLv3+
• lstParse.py - LGPLv3+
• defs.h - LGPLv3+
• app.c - LGPLv3+
• examples/serial/serial.c - LGPLv3+
• {hdmi2usb,examples}/Makefile - LGPLv3+

• read-serialno.h is LGPLv2.1+ -- https://github.com/timvideos/HDMI2USB-fx2-firmware/blob/master/hdmi2usb/read-serialno.c

I think the rest seem correct.

The license header for read-serialno.h specifically says version 3+: https://github.com/timvideos/HDMI2USB-fx2-firmware/blob/master/hdmi2usb/read-serialno.h#L6

Fixed read-serialno.h

We should aim to replace the following files;

• makestuff.h - LGPLv3+

  • This just contains some simple defines, very easy to replace.

• debug.h - LGPLv3+

  • What in this file is currently used?

• lstParse.py - LGPLv3+

  • Any idea where this is used? It seems to talk about TDO/TDI stuff which is all JTAG related things.

• defs.h - LGPLv3+

  • All the defs in here should already be in fx2lib
  • These defs are silly;

// Defines to allow use of camelCase.
#define mainInit(x) main_init(x)
#define mainLoop(x) main_loop(x)
#define handleVendorCommand handle_vendorcommand

• app.c - LGPLv3+
  • This file should be replaceable with stuff from the example firmware in fx2lib.

debug.h is currently used in softserial.h, as it has the functions for writing to serial
