[Libguestfs] [PATCH 2/2] actions: turn some params into RelativePathnameList (RHBZ#1174551).
Use RelativePathnameList as type for lists of relative paths, as used in
some listing-alike APIs. This way we can ensure absolute paths in those
lists are rejects outright.
As a consequence, test-big-dirs.pl does not need to prepend the
directory name anymore before calling listing-alike APIs: previously
they didn't fail, but the returned lists contained only invalid
elements (and only their size was checked).

That is to say: is "foo/bar" permitted, or just "bar"?
