 * dsgw_utf8casecmp: case-insensitive string compare for UTF-8 strings

 *                   0, if the two strings are identical ignoring the case
 *                   negative number, if s1 is after s0
 *
 * Rules: If both UTF-8 strings are NULL or 0-length, 0 is returned.
 *        If one of the strings is NULL or 0-length, the NULL/0-length
 *            string is smaller.
 *        If one or both of the strings are not UTF-8, system provided
 *            strcasecmp is used.
 *        If one of the two strings contains no 8-bit characters,
 *            strcasecmp is used.
 *        The strings are compared after converted to lower-case UTF-8.
 *        Each character is compared from the beginning.
 *            Evaluation goes in this order:
 *            If the length of one character is shorter then the other,
 *                the difference of the two lengths is returned.
 *            If the length of the corresponsing characters is same,
 *                each byte in the characters is compared.
 *                If there's a difference between two bytes,
 *                the diff is returned.
 *            If one string is shorter then the other, the diff is returned.
 *
 * Notes: Don't use this function for collation
 *        1) there's no notion of locale in this function.
 *        2) it's UTF-8 code order, which is different from the locale
 *           based collation.
