The powerpc version only supported 64 bit. Add some
code to switch decoding of fields during runtime so
we can kexec a 32 bit kernel from a 64 bit kernel and
vice versa.

Right now powerpc provides an implementation to read elf files
with the kexec_file_load() syscall. Make that available as a public
kexec interface so it can be re-used on other architectures.

With some corrupted vmcore files, the vmcore-dmesg.txt file may grow
forever till the kdump disk becomes full, and also probably causes
the disk error messages as follow:
...
sd 0:0:0:0: [sda] tag#6 FAILED Result: hostbyte=DID_BAD_TARGET
driverbyte=DRIVER_OK
sd 0:0:0:0: [sda] tag#6 CDB: Read(10)
Here, no need to wrap the read_elf() again, lets invoke it directly.
So remove the read_elf_kcore() and clean up redundant code.

[PATCH 1/4] Cleanup: remove the read_elf_kcore()
Here, no need to wrap the read_elf() again, lets invoke it directly.
So remove the read_elf_kcore() and clean up redundant code.
[PATCH 2/4] Fix an error definition about the variable 'fname'
The variable 'fname' is mistakenly defined two twice,
Some code related to vmcore-dmesg.c is put into the util_lib, which
is not very reasonable, so lets move it back and tidy up those code.
In addition, that will also help to limit the size of vmcore-dmesg.txt
in vmcore-dmesg.c instead of elf_info.c.

The variable 'fname' is mistakenly defined two twice, the first definition
is in the vmcore-dmesg.c, and the second definition is in the elf_info.c.
That is confused and incorrect although it's a static type, because the
value of variable 'fname' is not assigned(set) in elf_info.c. Anyway, its
