Pull the latest headers for Xen which allow us to add support for ARM and use new features in FreeBSD. This is a verbatim copy of the xen/include/public so every headers which don't exits anymore in the Xen repositories have been dropped. Note the interface version hasn't been bumped, it will be done in a follow-up. Although, it requires fix in the code to get it compiled: - sys/xen/xen_intr.h: evtchn_port_t is already defined in the headers so drop it. - {amd64,i386}/include/intr_machdep.h: NR_EVENT_CHANNELS now depends on xen/interface/event_channel.h, so include it. - {amd64,i386}/{amd64,i386}/support.S: It's not neccessary to include machine/intr_machdep.h. This is also fixing build compilation with the new headers. - dev/xen/blkfront/blkfront.c: The typedef for blkif_request_segmenthas been dropped. So directly use struct blkif_request_segment Finally, modify xen/interface/xen-compat.h to throw a preprocessing error if __XEN_INTERFACE_VERSION__ is not set. This is allow us to catch any file where xen/xen-os.h is not correctly included.
