instantiate the class with one of these arguments (or none):
- *path*, the path to a metadata file
- *fileobj* give a file-like object with metadata as content
- *mapping* is a dict-like object
- *scheme* is a version scheme name

Behavior is like `dict.update`: If `other` has a ``keys`` method,
they are looped over and ``self[key]`` is assigned ``other[key]``.
Else, ``other`` is an iterable of ``(key, value)`` iterables.
Keys that don't match a metadata field or that have an empty value are
dropped.
