Make some unwise casts. On i386 these casts wind up being safe. Rather
than disturb the API, go with these casts to shut gcc up.

  methods.

Remove custom bus scanner code and fix use of CAM's default scanner.

This fixes kernel panic during boot, caused by incompatibility of recent

Fix a lock-order reversal in the net driver by dropping the lock
  and holding a reference prior to calling further into the hyperv
  stack.

  Added missing FreeBSD idents.

716c2031c7 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.

c8195f5331 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.
