The code was successfully tested with FreeBSD, Linux, Solaris and Windows
guests. This interface is predictably slower (about 2x) then virtio-net,
but it is very helpful for guests not supporting virtio-net by default.
Thanks to Jeremiah Lott and Peter Grehan for doing original heavy lifting.
It was useless before, but may improve performance now if multiple devices
are configured and guest supports this feature.

While old syntax is still supported, new syntax looks like this:

Add `WRAPPED_CTASSERT` macro by annotating CTASSERTs with __unused
to deal with -Wunused-local-typedefs warnings from gcc 4.8+.
All other compilers (clang, etc) use CTASSERT as-is. A more generic
solution for this issue will be proposed after ^/stable/11 is forked.
Consolidate all CTASSERTs under one block instead of inlining them in
functions.

this on the branch.
Original commit message:
Initial bhyve native graphics support.
This adds emulations for a raw framebuffer device, PS2 keyboard/mouse,
XHCI USB controller and a USB tablet.
A simple VNC server is provided for keyboard/mouse input, and graphics
output.
A VGA emulation is included, but is currently disconnected until an
additional bhyve change to block out VGA memory is committed.
Credits:
- raw framebuffer, VNC server, XHCI controller, USB bus/device emulation
and UEFI f/w support by Leon Dang
- VGA, console/g, initial VNC server by tychon@
- PS2 keyboard/mouse jointly done by tychon@ and Leon Dang
- hypervisor framebuffer mem support by neel@
Tested by: Michael Dexter, in a number of revisions of this code.
With the appropriate UEFI image, FreeBSD, Windows and Linux guests can
installed and run in graphics mode using the UEFI/GOP framebuffer.

A couple of minor memory size option related nits:
- use common name 'memsize' (instead of 'max-size' or just 'size')
- bhyve: update usage with memsize unit suffix, drop legacy "MB"
unit
- bhyveload: update usage with memsize unit suffix
- bhyve(8): document default size
- bhyveload(8): use memsize formatting like it's done
in bhyve(8)

Previously, many errors (such as the PCI device not being attached
to the ppt(4) driver) resulted in bhyve silently exiting without
starting the virtual machine. Now any errors encountered when
configuring a virtual slot for a PCI passthru device should be noted
on stderr.

The buffer length should be checked to avoid overflow, but there
is no API to get the slot length, so the hardcoded value is used.

This is used by UEFI (and potentially other BIOSs/firmware) to
