Other things, mainly to get create_mysqld_error_find_printf_error tool to work: - Added protection to not include mysqld_error.h twice - Include "unireg.h" instead of "mysqld_error.h" in server - Added protection if ER_XX messages are already defined - Removed wrong calls to my_error(ER_OUTOFMEMORY) as my_malloc() and my_alloc will do this automatically - Added missing %s to ER_DUP_QUERY_NAME - Removed old and wrong calls to my_strerror() when using MY_ERROR_ON_RENAME (wrong merge) - Fixed deadlock error message from Galera. Before the extra information given to ER_LOCK_DEADLOCK was missing because ER_LOCK_DEADLOCK doesn't provide any extra information. I kept #ifdef mysqld_error_find_printf_error_used in sql_acl.h to make it easy to do this kind of check again in the future
