SHOW STATUS are not anymore put in slow query log because of no index usage. Implemntation done by removing orig_sql_command and moving logic of SHOW STATUS to mysql_excute_command() This simplifies code and allows us to remove some if statements all over the code. Upgraded uc_update_queries[] to sql_command_flags and added more bitmaps to better categorize commands. This allowed some overall simplifaction when testing sql_command. Fixes bugs: Bug#10210: running SHOW STATUS increments counters it shouldn't Bug#19764: SHOW commands end up in the slow log as table scans
