 * @name FsRtlDissectDbcs
 * @implemented
 *
 * Dissects a given path name into first and remaining part.
 *
 * @param Name
 *        ANSI string to dissect.
 *
 * @param FirstPart
 *        Pointer to user supplied ANSI_STRING, that will later point
 *        to the first part of the original name.
 *
 * @param RemainingPart
 *        Pointer to user supplied ANSI_STRING, that will later point
 *        to the remaining part of the original name.
 *
 * @return None
 *
 * @remarks Example:
 *          Name:           \test1\test2\test3
 *          FirstPart:      test1
 *          RemainingPart:  test2\test3
