Walk location returning the same tuples as os.walk but with a different
behavior:
- always walk top-down, breadth-first.
- always ignore and never follow symlinks (unless `follow_symlinks` is True),
- always ignore special files (FIFOs, etc.)
- optionally ignore files and directories by invoking the `ignored`
callable on files and directories returning True if it should be ignored.
- location is a directory or a file: for a file, the file is returned.
If `follow_symlinks` is True, then symlinks will not be ignored and be
collected like regular files and directories
