565bbb8698 Move the ioapic device model from userspace into vmm.ko. This is needed for 
upcoming in-kernel device emulations like the HPET.

The ioctls VM_IOAPIC_ASSERT_IRQ and VM_IOAPIC_DEASSERT_IRQ are used to
manipulate the ioapic pin state.

03cd05011f Remove the 'vdev' abstraction that was meant to sit on top of device models 
in the kernel. This abstraction was redundant because the only device emulated
inside vmm.ko is the local apic and it is always at a fixed guest physical
address.

b01c203325 Corral all the host state associated with the virtual machine into its own file. 
This state is independent of the type of hardware assist used so there is
really no need for it to be in Intel-specific code.

a2da7af6bc Add support for trapping MMIO writes to local apic registers and emulating them. 
The default behavior is still to present the local apic to the guest in the
x2apic mode.

d7e0c54045 BHyVe's vmm.ko can now be built with the in-tree binutils. 
Many thanks to jhb@ for making this happen.

6c212efc25 Missed this in the previous commit to add 'show vmcs': add opt_ddb.h as 
a source file.

17debe0d59 Remove misleading macro definition (-DOLD_BINUTILS) from CFLAGS. 
At this point we require binutils from ports that understands how to
assemble the VT-x instructions.

BHyVe reference branch to HEAD.

366f60834f Import of bhyve hypervisor and utilities, part 1. 
vmm.ko - kernel module for VT-x, VT-d and hypervisor control
  bhyve  - user-space sequencer and i/o emulation
  vmmctl - dump of hypervisor register state
  libvmm - front-end to vmm.ko chardev interface

bhyve was designed and implemented by Neel Natu.

Thanks to the following folk from NetApp who helped to make this available:
	Joe CaraDonna
	Peter Snyder
	Jeff Heller
	Sandeep Mann
	Steve Miller
