[v1.3.3-09] Add a new option "--split" for dumping multiple dumpfiles.
A new option "--split":
Split the dump data to multiple dumpfiles in parallel.
If specifying dumpfiles on different storage devices, a device can share
I/O load with other devices and it reduces time for saving the dump data.
The file size of each dumpfile is smaller than the system memory size which
is divided by the number of dumpfiles.
This feature supports only the kdump-compressed format.
Example:
# makedumpfile --split -d 31 -x vmlinux /proc/vmcore dumpfile1 dumpfile2
