kexec jump support for kexec-tools
To support memory backup/restore an option named --load-preserve-context is added to kexec. When it is specified toggether with --mem-max, most segments for crash dump support are loaded, and the memory range between mem_min to mem_max which has no segments loaded are loaded as backup segments. To support jump back from kexeced, options named --load-jump-back-helper and --entry are added to load a helper image with specified entry to jump back.
