- Added sql/mariadb.h file that should be included first by files in sql directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables that must be done before my_global.h is included) - Removed a lot of include my_global.h from include files - Removed include's of some files that my_global.h automatically includes - Removed duplicated include's of my_sys.h - Replaced include my_config.h with my_global.h
