Rearrange grub-core/kern/xen/init.c to prepare adding PVH mode support
to it. This includes putting some code under #ifdef GRUB_MACHINE_XEN

Initialize the grant tab in a dedicated function. This will enable
using it for PVH guests, too.
Call the new function from grub_machine_init() as this will later
be common between Xen PV and Xen PVH mode.

Support mkimage for xenpvh.
In order to avoid using plain integers for the ELF notes use the

Today the domain config info contains the cpupool name the domain was
started in only if the cpupool was specified at domain creation. Moving
the domain to another cpupool later won't change that information.
Correct that by modifying the domain config accordingly.

The Xen specific queue spinlock wait function has two issues which
could result in a hanging system.
They have a similar root cause of clearing a pending wakeup of a
waiting vcpu and later going to sleep waiting for the just cleared
wakeup event, which of course won't ever happen.
