* Removed integer_fields check * Reworked Vers_parse_info::check_sys_fields() * Misc renames * versioned as vers_sys_type_t * Removed versioned_by_sql(), versioned_by_engine() versioned() works as before; versioned(VERS_TIMESTAMP) is versioned_by_sql(); versioned(VERS_TRX_ID) is versioned_by_engine(). * create_tmp_table() fix * Foreign constraints for timestamp-based * Range auto-specifier fix * SQL: 1-row partition rotation fix [fixes #260] * Fix 'drop system versioning, algorithm=inplace'
