"getGeneratedKeys() does not work with FEDERATED table"
mysql_insert() expected the storage engine to update the row data
during the write_row() operation with the value of the new auto-
increment field. The field must be updated when only one row has
been inserted as mysql_insert() would ignore the thd->last_insert.
This patch implements HA_STATUS_AUTO support in ha_federated::info()
and ensures that ha_federated::write_row() does update the row's
auto-increment value.
The test case was written in C as the protocol's 'id' value is
accessible through libmysqlclient and not via SQL statements.
mysql-test-run.pl was extended to enable running the test binary.
