 *

 * @details

 *

 * Previously, the mysql_priv.h file contained a number of conditional

 * #ifdef DRIZZLE_SERVER blocks which made it very difficult to determine

 * which headers and definitions were actually necessary for plugins to 

 * include.  The file, and NOT mysql_priv.h, should now be the main included

 * header for storage engine plugins, as it contains all definitions and 

 * declarations needed by the plugin and nothing more.
