Add utility function to fixup Windows file paths
The idea is to iterate over a (canonicalized) path with forward slashes by components, i.e. file and directory names. Each name is then looked at by iterating over components, i.e. everything between dots. If a component is an illegal name, like COM1 or AUX, we add an underscore. If it contains illegal characters, like : or \, we re-map that character into unicode private use area. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
