This is used by InnoDB to detect if CREATE...SELECT is used
Other things:
- Changed InnoDB to use thd_ddl_options()
- Removed lock checking code for create...select (Approved by Marko)
- Defining MariaDB_FUNCTION_PLUGIN
- Changing the code in /plugins/type_inet/ and /plugins/type_test/
to use MariaDB_FUNCTION_PLUGIN instead of MariaDB_FUNCTION_COLLECTION_PLUGIN.
- Changing maturity for the INET6 data type plugin from experimental to alpha.
