kexec: implemented XEN KEXEC STATUS to determine if an image is loaded
Instead of the scripts having to poke at various fields we can
provide that functionality via the -S parameter.
kexec_loaded/kexec_crash_loaded exposes Linux kernel kexec/crash
state. It does not say anything about Xen kexec/crash state. So,
we need a special approach to get the latter. Though for
compatibility we provide similar functionality in kexec-tools
for the former.
This change enables the --status or -S option to work either
with or without Xen.
Returns 0 if the payload is loaded. Can be used in combination
with -l or -p to get the state of the proper kexec image.
