Under terms of MDEV 27490 we'll add support for non-BMP identifiers and upgrade casefolding information to Unicode version 14.0.0. In Unicode-14.0.0 conversion to lower and upper cases can increase octet length of the string, so conversion won't be possible in-place any more. This patch removes virtual functions performing in-place casefolding: - my_charset_handler_st::casedn_str() - my_charset_handler_st::caseup_str() and fixes the code to use the non-inplace functions instead: - my_charset_handler_st::casedn() - my_charset_handler_st::caseup()
