 * Revision 1.8  2003/01/15 14:05:11  josh
 * directory structure shifting
 *
 * Revision 1.7  2002/03/19 19:36:12  josh
 * break down the main MIB tree so it doesn't include AgentX objects
 * anymore.  instead, the AgentX MIB objects are built into a separate
 * MIB tree file which will only be used when the AgentX code is included
 * in the project facility.
 *
 * Revision 1.6  2001/12/07 20:36:38  meister
 * ax_dyncfg_init should be ax_master_dyncfg_init
 *
 * Revision 1.5  2001/11/12 22:54:52  meister
 * Changed some DYNCFG_FUNCPTR's to DYNCFG_EXTERN_FUNCPTR's
 *
 * Revision 1.4  2001/11/08 22:18:33  meister
 * rework pathnames
 *
 * Revision 1.3  2001/11/06 21:50:52  josh
 * second (and hopefully final) pass of new path hacking
 *
 * Revision 1.2  2001/11/06 21:20:39  josh
 * revised new path hacking
 *
 * Revision 1.1.1.1  2001/11/05 17:47:49  tneale
 * Tornado shuffle
 *
 * Revision 1.1.2.11  2001/11/02 21:15:10  meister
 * envoy/h/vxprotos.h -> snmp/vxagent/h/vxprotos.h
 *
 * Revision 1.1.2.10  2001/11/02 17:14:02  meister
 * split out user and core dynamic config
 *
 * Revision 1.1.2.9  2001/10/19 21:50:48  meister
 * snmpdInstalledComponentsValue should be unsigned in all references.
 *
 * Revision 1.1.2.8  2001/10/19 21:34:17  meister
 * fix minor typos
 *
 * Revision 1.1.2.7  2001/10/19 21:09:33  meister
 * get rid of the message-queue method of communicating which components
 * are installed, in favor of a directly accessible bit-mask variable. We never
 * never used the message queue for anything the simple bit mask couldnt do.
 *
 * Revision 1.1.2.6  2001/10/16 20:18:05  meister
 * Add prototypes for axMasterIoInit, and snmpAxMonitorSpawn. They dont
 * belong here. axCfg.h needs to be fixed and then they can be removed from
 * here.
 *
 * Revision 1.1.2.5  2001/10/16 19:53:01  meister
 * Tornado 2 doesnt have a VX_USER_MODE #define.
 *
 * Revision 1.1.2.4  2001/10/16 18:31:18  meister
 * dynamic pointers for snmpdAxMonitorSpawn, initAxMonitor
 *
 * Revision 1.1.2.3  2001/09/27 01:10:15  meister
 * Split out coexistence support into V3 component
 *
 * Revision 1.1.2.2  2001/09/18 16:36:15  meister
 * snmpd config msgQ and mutex should have consistent names.
