* UnixDriveInfo.cs: Properties should generate an InvalidOperationException,

    not an IOException.  Users can use IsReady to avoid exception generation.
  * UnixIOException.cs: Create a custom message that embeds the error name
    within the text, e.g. "Permission denied [EACCES]."
  * UnixSymbolicLinkInfo.cs: This really should create the file FullPath, not
    OriginalPath.  Created files shouldn't ever be relative to the current
    working directory, as this can change at any time.
