Hello Tachibana-san,

Since there's certain time until Tachibana-san's review, I made some
cleanups and bugfixes to the previous version. Could you review this
instead to reduce the review time?

The following series implements Fujitsu stand-alone dump (sadump)
format support for makedumpfile, converting sadump-related formats
into kdump-compressed format.

Based on makedumpfile version 1.4.0.

Here is summary of the changes.

No debug information on sadump-related formats

Unlike other dump mechanisms, VMCORE created by sadump has NO debug
information including VMCOREINFO. So, -x VMLINUX is definitely

Debug information gained from VMLINUX is used for:

    1. creating VMCOREINFO dynamically, saved in resulting dumpfiles
       in kdump-compressed format, and

    2. gaining symbolic and type information necessary to refer to ELF
       note information contained in VMCORE generated by kdump at
       crash, and to estimate phys_base value.

If no VMLINUX is specified, dumpfile with no VMCOREINFO and ELF note
is generated on the current implementation.

Command-line interface change

Introduce --diskset=VMCORE to pass multiple VMCOREs in a single
commnad-line input.

    makedumpfile [OPTION] -x VMLINUX --diskset=VMCORE1 --diskset=VMCORE2 \
    [--diskset=VMCORE3 ..] DUMPFILE


X86 and X86_64.

On the other unsupported architectures, sadump-related source files
are never compiled and linked into makedumpfile executable.
