alias GUIDs are those indicated in SM GUIDInfo attribute (other than index 0) and are created/removed via SA Set/Delete of GUIDInfoRecord per IBTA MgtWG errata RefIDs 4704-4706. Up to now, this attribute was unneeded by the SM as only base port GUIDs were supported (and are available from the SM NodeInfo attribute). In order to support alias GUIDs, a new alias GUID table is to be added indexed by alias GUID, each containing a pointer to the base port. The routines for creating and removing alias GUID table entries are added by this patch. Also, a pointer to the alias port GUIDs provided by the SM GUIDInfo attribute is added to the osm_physp_t structure.
