785e09b08f In sys/dev/hyperv, fix a number of gcc warnings about usage of anonymous
union members in strict C99, by giving them names.  While here, add some
FreeBSD keywords where they were missing.

bf57e9793a Correct panic caused by attaching both Xen PV and HyperV virtualization
aware drivers on Xen hypervisors that advertise support for some
HyperV features.

x86/xen/hvm.c:
	When running in HVM mode on a Xen hypervisor, set vm_guest
	to VM_GUEST_XEN so other virtualization aware components in
	the FreeBSD kernel can detect this mode is active.

dev/hyperv/vmbus/hv_hv.c:
	Use vm_guest to ignore Xen's HyperV emulation when Xen is
	detected and Xen PV drivers are active.

- change the SI_SUB_RUN_SCHEDULER sysinits in hv_utilc and
hv_netvsc_drv_freebsd.c to SI_SUB_KTHREAD_IDLE, since the
former is no longer in FreeBSD.
  The use of these SYSINITs can probably be removed.

cc759c1995 Microsoft have changed their policy on how the hyper-v code will
be pulled into FreeBSD. From now, FreeBSD will be considered the
upstream repo.

First step: move the drivers away from the contrib area and into
the base system.

A follow-on commit will include the drivers in the amd64 GENERIC kernel.
