Problem: SHOW CREATE TABLE printed garbage in table name for tables having TURKISH I (i.e. LATIN CAPITABLE LETTER I WITH DOT ABOVE) when lower-case-table-name=1. Reason: In some cases during lower/upper conversion in utf8, the result string can be shorter the original string (including the above letter). Old implementation of caseup_str() and casedn_str() didn't handle the result length properly, assuming that length cannot change. This fix changes the result type of cs->cset->casedn_str() and cs->cset->caseup_str() from VOID to UINT, to return the result length, as well as put '\0' terminator on a proper place. Also, my_caseup_str_utf8() and my_casedn_str_utf8() were rewritten not to use strlen() for performance purposes. It was done with help of adding of new functions - my_utf8_uni_no_range() and my_uni_utf8_no_range() - for null terminated strings.
