Reasoning:
- implementation was unsound -- broke down when I added a fairly
basic macro definition expanding to a struct initializer in a *.c
file.
- made it way too easy (e.g. via otherwise totally innocuous git
commands) to end up with timestamps such that it always ran
MakeHeader.py but never used its output, leading to overbuild noise
when running what should be a null 'make'.
- but mostly: it's just an awkward way of dealing with C code.
Use configure.ac to handle platform differences where some
build hosts have only a python3, or only python, binary.

Extends the MakeHeader script to auto-generate correct "extern"
function declarations in some cases that it currently does not.

Header creation fails with non-utf8 locale and python3.
Simply set LC_ALL="C" and use python3 to reproduce the issue.
env LC_ALL="C" ./scripts/MakeHeader.py MetersPanel.c

This changes is python2 and python3 compatible
cStringIO.StringIO module is removed because it is not able to accept unicode strings
