Remove the unscoped #pragma GCC diagnostic ignored "-Wdeprecated-declarations" from include/violite.h and replace all sprintf/vsprintf calls with snprintf/vsnprintf across the codebase. Where possible, pass actual buffer sizes as function parameters instead of using hardcoded constants or recomputing strlen(). Notable API changes: - get_date(): added to_len parameter for buffer size - nice_time(), end_timer() in client/mysql.cc: added buff_size - generate_new_name(): added name_size parameter - calc_md5(): added buffer_size parameter (fixes off-by-one) - MD5_HASH_TO_STRING macro: added _size parameter - Added MYSQL_UDF_MAX_RESULT_LENGTH constant in mysql_com.h Also fixed a pre-existing bug in sql/rpl_mi.cc where the ellipsis "..." was written to the wrong buffer (dbuff instead of buff). Vendored code is excluded: extra/readline, extra/wolfssl, wsrep-lib, libmariadb, storage/mroonga/vendor, zlib.
