f821a3c174 zdump: Drop support of 32-bit dump architecture
- Initialize dump and dump-tool architecture to DFI_ARCH_64 at the start
  of dfi_init() and dt_init() respectively.
- Bail out if any dump architecture other than ARCH_64 has been detected
  in s390_ext or s390mv_ext DASD dump header.
- Remove redundant dfi_arch_set() and dt_arch_set() functions.
- Get rid of l.arch local variables in dfi* and dt* source files and
  drop dfi_arch() function.
- Drop the usage of DFI_ARCH_32 and compeletely remove DFI_ARCH_UNKNOWN.
- Drop special register and lowcore processing functions used
  for DFI_ARCH_32.
- Drop df_s390_from_dfi_arch() and df_s390_to_dfi_arch() funcitons.
- Update the man file for zgetdump.

ee4cb78dc2 zdump: Drop non-extended multi-volume DASD dump support
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.

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.

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
