*
* Validate a string as UTF-8 encoded according to RFC 3629
*
* Simply, a unicode code point (up to 21-bits long) is encoded as follows:
*
* Char. number range | UTF-8 octet sequence
* (hexadecimal) | (binary)
* --------------------+---------------------------------------------
* 0000 0000-0000 007F | 0xxxxxxx

* 0001 0000-0010 FFFF | 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx
*
* Validation is done left-to-right, and an error condition, if any, refers to
* only the left-most problem in the string.
*
* Return values:
* UTF8_VALID: Valid UTF-8 encoded string
* UTF8_OVERLONG: Using more bytes than needed for a code point
* UTF8_SHORT_TAIL: Not enough bytes in a multi-byte sequence
* UTF8_LONG_TAIL: Too many bytes in a multi-byte sequence
