Mikhail Zaslonko 6f82c5792a zdump: Drop support of non-extended single volume DASD dumpers
Since DASD standalone dumper does not support non-extended s390 dump
format for years, drop zgetdump support of non-extended s390 single volume
DASD dump-tool:
- Merge dt_390sv_ext.c and dt_s390sv.c counterparts.
- Update DT vector of supported dump tools removing dt_s390sv entry and
  keeping dt_s390sv_ext entry for s390 single volume extended dump tool.
- Remove dt_s390sv.c source and update the Makefile accordingly.
- Remove magic constants relevant to non-extended s390 single volume DASD
  dumper.
- Drop s390 single volume DASD dumper version 5 in df_s390_dumper_read().

Note: We still need support of non-extended s390 dump format since such
output dump files can be produced by 'zgetdump -f s390' via dfo_s390. Thus,
both dfi_s390 and dfi_s390_ext DFI vector entries remain in order to
process s390 dumps files as well as s390_ext dumps on the DASD partition.

Alexander Egorenkov 0466760ec1 zdump: Implement DT interface for NGDump
The NGDump DT interface enables zgetdump to display various meta
information contained within a dump partition prepared for NGDump
stand-alone dump.

Usage example:
--------------

No dump yet made
----------------

$ zgetdump -d /dev/nvme0n1
Dump device info:
  Dump tool.........: Next Generation (NGDump) dump tool
  Version...........: 1
  Architecture......: s390x (64 bit)

Partition info:
  Partition number..: 1

Dump present
------------

$ zgetdump -d /dev/nvme0n1
Dump device info:
  Dump tool.........: Next Generation (NGDump) dump tool
  Version...........: 1
  Architecture......: s390x (64 bit)

Partition info:
  Partition number..: 1
Meta info:
  File..............: dump.elf

Alternative disk path
---------------------

$ zgetdump -d /dev/disk/by-id/nvme-eui.01000000010000005cd2e4c5bc845051
Dump device info:
  Dump tool.........: Next Generation (NGDump) dump tool
  Version...........: 1
