tunables to modify the default cpu topology advertised by bhyve.
Also add a tunable "hw.vmm.topology.cpuid_leaf_b" to disable the CPUID
leaf 0xb. This is intended for testing guest behavior when it falls back
on using CPUID leaf 0x4 to deduce CPU topology.
The default behavior is to advertise each vcpu as a core in a separate soket.
the vcpu had no caches at all. This causes problems when executing applications
in the guest compiled with the Intel compiler.

The Qualcomm Atheros reference design code goes through significant
hacks to shut down RX before TX. It doesn't even try do do it in the
driver - it actually makes the DMA stop routines in the HAL shut down
RX before shutting down TX.
So, to make this work for chips that aren't the AR9380 and later, do
it in the driver. Shuffle the TX stop/drain HAL calls to be called
*after* the RX stop HAL call.
Tested:
* AR5413 (STA)
* AR5212 (STA)
* AR5416 (STA)
* AR9380 (STA)
* AR9331 (AP)
* AR9341 (AP)
TODO:
* test ar92xx series NIC and the AR5210/AR5211, in case there's something
even odder about those.

There were situations where the cursor was not erased/redrawn or its
position was marked as dirty even though it's not displayed. The code is
now more straightforward.
At the same, add a function to determine if the cursor covers a given
area. This is used by backends to know if they need to draw the cursor.
This new function should be paired with a new state in struct vt_device,
called vd_mshown, which indicates if the cursor should be displayed.
This again simplifies vd_bitblt_text_t callback's API.

In textmode, no font is loaded, thus the page fault in
vt_mark_mouse_position_as_dirty() when it wants the font width/height.
For now, create a fake area for the textmode. This needs to be modified
if vt_vga gains mouse support in textmode.
While here, fix a build failure when SC_NO_CUTPASTE is defined:
vt_mark_mouse_position_as_dirty() must not be included in this case.

- It was decided to change the driver name to if_ixl for FreeBSD
- This release adds the VF Driver to the tree, it can be built into
the kernel or as the if_ixlv module
- The VF driver is independent for the first time, this will be
desireable when full SRIOV capability is added to the OS.
- Thanks to my new coworker Eric Joyner for his superb work in
both the core and vf driver code.
Enjoy everyone!

This patch contains the following fixes for netback:
- Only unbind the evtchn if it has been bound.
- Set xnb->bridge to NULL after free to prevent double-freeing it.
- Set the MAC address for the host-facing interface to a dummy value.

This is needed so when running under Xen the calls to pci_child_added
can be intercepted and a custom Xen method can be used to register
those devices with Xen. This should not include any functional
change, since the Xen implementation will be added in a following
patch and the native implementation is a noop.
