The current path of the Xen headers at /sys/xen/interface/ is not correct, as those headers are imported verbatim from the Xen sources and shouldn't be modified, as any modifications would be lost when a new version is imported. Changes to the public headers must be first done in Xen upstream so that they can be backported and new imports will already carry them. Import Xen 4.16 headers in sys/contrib/xen/. It's unlikely that we will import different Xen code, so don't place them inside of any subdirectory. If in the future other pieces of Xen code need to be imported the headers will need to move into an include/ subdirectory. Note that this commit does not yet modify the include path to use the newly imported headers. Sponsored by: Citrix Systems R&D
