[SETUPLIB][USETUP] Transform the existing ConcatPaths() function into a variadic
function, and derive a CombinePaths() from it (plus their equivalent taking va_list).
This allows building concatenated paths with an arbitrary number of separated
components.
- Use the newly-introduced CombinePaths() and ConcatPaths() functions.
- Fix also few comments, and place some UNICODE_NULLs here & there.
