This was done in, among other things: - thd->db and thd->db_length - TABLE_LIST tablename, db, alias and schema_name - Audit plugin database name - lex->db - All db and table names in Alter_table_ctx - st_select_lex db Other things: - Changed a lot of functions to take const LEX_CSTRING* as argument for db, table_name and alias. See init_one_table() as an example. - Changed some function arguments from LEX_CSTRING to const LEX_CSTRING - Changed some lists from LEX_STRING to LEX_CSTRING - threads_mysql.result changed because process list_db wasn't always correctly updated - New append_identifier() function that takes LEX_CSTRING* as arguments - Added new element tmp_buff to Alter_table_ctx to separate temp name handling from temporary space - Ensure we store the length after my_casedn_str() of table/db names - Removed not used version of rename_table_in_stat_tables() - Changed Natural_join_column::table_name and db_name() to never return NULL (used for print) - thd->get_db() now returns db as a printable string (thd->db.str or "")
