The datamover suite had no EC coverage for the mpifileutils tools, and
no object-level dsync test at all. Add dcp, dsync and daos-serialize
variants to DmvrObjEcTest, and a dsync test to DmvrObjSmallTest.

DmvrObjEcTest now writes byte granular whole stripes and punches some of
them, and dataset_verify_ec checks the io map rather than just the
bytes. Add IORequest.insert_recx, fetch_recx and fetch_recx_map, plus
daos_iom_t to daos_cref, to make that possible.

dataset_gen and dataset_verify learn punch_extents and
punch_tail_extents, used by DmvrObjSmallTest to make its arrays sparse.
