394e3bd088 Fix CARP when in use in a HyperV environment:
- Bump link state when stopping or starting the interface;
 - Don't handle SIOCGIFADDR specially, similar to r277103.

This change is based on a previous revision from Andy Zhang
(Microsoft) who did the diagnostic work and many thanks to
them for their help in supporting the HyperV work.

85c9dd9d89 Prevent overflow issues in timeout processing
Previously, any timeout value for which (timeout * hz) will overflow the
signed integer, will give weird results, since callout(9) routines will
convert negative values of ticks to '1'. For unsigned integer overflow we
will get sufficiently smaller timeout values than expected.

Switch from callout_reset, which requires conversion to int based ticks
to callout_reset_sbt to avoid this.

Also correct isci to correctly resolve ccb timeout.

This was based on the original work done by Eygene Ryabinkin
<rea@freebsd.org> back in 5 Aug 2011 which used a macro to help avoid
the overlow.

833e8dc5ab Remove struct arpcom. It is unused by most interface types, that allocate
it, except Ethernet, where it carried ng_ether(4) pointer.
For now carry the pointer in if_l2com directly.

e72055b7fe Import HyperV Key-Value Pair (KVP) driver and daemon code by Microsoft,
many thanks for their continued support of FreeBSD.

While I'm there, also implement a new build knob, WITHOUT_HYPERV to
disable building and installing of the HyperV utilities when necessary.

The HyperV utilities are only built for i386 and amd64 targets.

This is a stable/10 candidate for inclusion with 10.1-RELEASE.

3e5a6bd16d 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.

feeec74df7 More BUS_PROBE_NOWILDCARD sweeping. Some devices here (if_ath_ahb and siba)
resist easy conversion since they implement a great deal of their attach
logic inside probe(). Some of this could be fixed by moving it to attach(),
but some requires something more subtle than BUS_PROBE_NOWILDCARD.

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.

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.
