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.

This typo was introduced in c/s c0b4a3f95dd80256cc6d7084436235e69b4933fb
It prevents a 32bit build of kexec from loading a 32bit crash image.

Correct various problems introduced by
08cf823704b0fa3b ("kexec/xen: directly load images images into Xen").
These all relate to the case here HAVE_LIBXENCTRL is not set.

Xen 4.4 has an improvided kexec hypercall ABI that allows images to be
loaded and executed without any kernel involvement. Use the API
provided by libxc to load images when running in a Xen guest.
Support for loading images via the kexec_load syscall in non-upstream
("classic") Xen kernels is no longer supported.
