zdump: Implement DFI interface for NGDump
The NGDump DFI interface enables zgetdump to read and mount dumps created
with NGDump stand-alone dump.
Under the hood, the NGDump DFI delegates the task of reading and
parsing of ELF dump files to the ELF DFI interface dfi_elf.
Usage example 1:
----------------
$ zgetdump -i /dev/nvme0n1p1
General dump info:
Dump format........: elf
Version............: 1
UTS node name......: t83lp49.lnxne.boe
UTS kernel release.: 5.14.0-20210819.rc6.git0.efb8a921eec7.300.fc34.s390x
UTS kernel version.: #1 SMP Thu Aug 19 00:22:04 CEST 2021
System arch........: s390x (64 bit)
CPU count (online).: 32
Dump memory range..: 16384 MB
Memory map:
0000000000000000 - 00000003ffffffff (16384 MB)
Usage example 2:
----------------
$ zgetdump /dev/nvme0n1p1 > dump.elf
