Adapted a patch set from NEC and Fujitsu that introduces support
    for an alternative compressed dumpfile format created by the
    diskdump facility.  When the diskdump facility is configured to
    use compression, the dumpfile will not be an ELF vmcore file,
    but rather a compressed dumpfile image, derived from the LKCD
    dumpfile format.
