Ian,
As we discussed previously,
http://patchwork.ozlabs.org/patch/457055/
now it's time to push this into on xen/tools side since all qemu stuffs
have been merged.

Ian,
Actually we had v3.5 online previously, which was reviewed by you.
http://permalink.gmane.org/gmane.comp.emulators.qemu/329100
So here I just bring a little bit to refine code just for patch #2
according to out last conversation.
v3:
* Refine some codes based on Campbell's feedback so thanks for Campbell's
kind guideline to patch #2
* Update the manpages in patch #2
v2:
* Refine patch #2's head description
* Improve codes quality inside patch #1 based on Wei's comments
* Refill the summary inside patch #0 based on Konrad and Wei's suggestion
When we're working to support IGD GFX passthrough with qemu
upstream, instead of "-gfx_passthru" we'd like to make that
a machine option, "-machine xxx,igd-passthru=on".
https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02050.html
This need to bring a change on tool side.
After a discussion with Campbell, we'd like to construct a table to record
all IGD devices we can support. If we hit that table, we should pass that
option. And so we also introduce a new field of type, 'gfx_passthru_kind',
to cooperate with 'gfx_passthru' to cover all scenarios like this,
gfx_passthru = 0 => sets build_info.u.gfx_passthru to false
gfx_passthru = 1 => sets build_info.u.gfx_passthru to true and
build_info.u.gfx_passthru_kind to DEFAULT
gfx_passthru = "igd" => sets build_info.u.gfx_passthru to false
and build_info.u.gfx_passthru_kind to IGD
And note actually that option "-gfx_passthru" is just introduced to
work for qemu-xen-traditional so we should get this away from
libxl__build_device_model_args_new() in the case of qemu upstream.
