5. VolInfo interface

This should turn into the volume location server.

ViceGetVolumeInfo
        VRDB.find by name
        if not found try to find by id (VRDB.find nasty casts)
        if found: call
             vrent::GetVolumeInfo for the entry 
                     fills in VSGADD stuff
                     special case for canonicalize
                     fills in the replica volid's in INFO           
        else 
             VGetVolumeInfo
                     gets it out of the VLDB_fd
             if successful and ROVOL: calculate GetVSGAddress
             elseif RWVOL lookup the volumeinfo for a replicated volume
        return information
