 * 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.
