Switch to using DAOS to allocate object IDs, via daos_cont_alloc_oids. Encode DAOS private bits into the haddr_t form of OIDs. Note that this places an upper limit of 30 bits of object IDs before API functions that use haddr_t stop working. H5Oopen also has this restriction for now (though it will disappear once tokens are implemented).
