Add InnoDB version in these places:
 
* In INFORMATION_SCHEMA.PLUGINS.PLUGIN_VERSION, only 1.2 out of 1.2.3
  because MySQL supports only one dot there
 
* At startup:
  "080501 12:28:06 InnoDB Plugin 1.0.1 started; log sequence number 46509"

* In a server variable innodb_version;
  mysql> select @@innodb_version;
  +------------------+
  | @@innodb_version |

  | 1.0.1            |
