libutil: Add a stacked, recursive directory tree iterator
The concept is simple: Use the existing, platform dependent iterator
to walk a directory. If a directory entry is encountered, recurse into
it using the open_subdir handler, reconstruct the full path for any
entries discovered using the directory stack.
An additional function is added to skip a sub-hierarchy.
