This implements a simple DFS locator in listing structures.
It is interoperable with the Rust standard library paths, we also build our
own errors to restrict path values to reasonable secure defaults, e.g.
relative paths with no `..` component.
Tests are added for this new feature for a positive and a negative
check.
In addition, a path validation test was added. The Windows-style prefix
is gated on the Windows platform as UNIX does not parse `C:\\` as a
`Component::Prefix(_)` but as a `Component::Normal(_)`.

.ls files are useful to seek in a NAR without parsing it entirely.
The responsibility of validating the files is on the caller.
