Now vmbus_channel_on_offer() -> vmbus_channel_process_offer() can
safely run on the global hv_vmbus_g_connection.work_queue now.
We remove the per-channel control_work_queue to achieve the proper
serialization of the message handling.
I removed the bogus TODO in vmbus_channel_on_offer(): a vmbus offer
can only come from the parent partition, i.e., the host.

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.

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.
