Since memory chunks can overlap for vr-kernel dumps stored in elf format (ngdump, zfcpdump), we need to consider this when converting to s390 dump output format. For that sort DFI memory chunks by start address and adjust dfo_s390 logic for identifying memory gaps. Otherwise we might end up with bogus DFO memory chunks being created.
