Added new methods File.GetFileId and Directory.GetFileId that returns a unique file or directory identifier that can be used to determine if two paths refer to the same directory (symbolic links and junctions) or to the same file (symbolic links or hard links). The methods are compatible with FAT, NTFS and ReFS file systems.

To support ReFS file system (Windows 8+) this identifier is composed of 64-bit volume serial number and 128-bit file system entry identifier (see WINAPI structure FILE_ID_INFO and functions GetFileInformationByHandle and GetFileInformationByHandleEx - https://msdn.microsoft.com/cs-cz/library/windows/desktop/hh802691(v=vs.85).aspx)
