Since DASD standalone dumper does not support non-extended s390 multi-volume dumps for years, drop zgetdump support of non-extended s390_mv DASD dumps and dump-tools: - Merge dfi_s390mv_ext and dt_s390mv_ext with related dfi_s390mv and dt_s390mv counterparts. - Update DFI and DT vectors of supported dump formats and dump-tools removing dfi_s390mv and dt_s390mv entries and keeping dt_s390mv_ext and dfi_s390mv_ext ones for s390_mv extended dump and dump-tool accordingly. - Remove dfi_s390mv.c and dt_s390mv.c sources and update the Makefile. - Make dfi_s390mv_ext_init() and dfi_s390mv_info() static. - Remove magic number relevant to non-extended s390_mv DASD dumper. - Completely drop DASD dumper version 5 case in df_s390_dumper_read(). Note: Since non-extended s390 multi-volume dumps can reside on DASD partitions only and cannot be produced via DFO interface, we can drop this dump format entirely.
