UnixFile doesn't exist in 1.1.13.  It was in 1.1.12.

Those aren't direct equivalents.  UnixSymbolicLinkInfo.ContentsPath is
equivalent to UnixFile.ReadLink() -- it will throw an exception if there
was an error reading the link.  UnixFile.TryReadLink() can be simulated:

        // 1.1.12 Code:
        string target = UnixFile.TryReadLink ("sym-link");
        // 1.1.13 Code:
        UnixSymbolicLinkInfo symlink = new UnixSymbolicLinkInfo ("sym-link");
        string target = symlink.HasContents ? symlink.ContentsPath :
