This fixes a build error for PV guests (OpenBSD, NetBSD) where the use
of XEN_GUEST_HANDLE_64(uint8_t) leads to a build error because uint8_t
is a #define and not a typedef.

I have added CONFIG_PASSTHROUGH in ioemu/Makefile.target and
ioemu/hw/pc.c in attached vtd_tools2.patch. This should turn off
libpci usage by default until user specifically enables it.
This can be safely check-in without breaking builds for people who do
not care about pass-through devices. I will try to think of a better
way to enable this.

I don't know how significant this is (most of the NUMA node data seems
unused at this point), but anyway: enable proper operation of NUMA
emulation and the fake NUMA node in case there's no SRAT table on
x86-32. This will at least make the "Faking node ..." message not
print confusing information anymore.

I found that xend's memory usage grows considerably when running a
script such as
while true; do xm new foo ; sleep 2s; xm delete foo ; sleep 2s; done
XendAPIStore maintains a list of class instances and in the case of
new/create operation, an associated VMMetrics object is stashed in the
list but never removed on delete/shutdown. This patch removes the
instance by invoking XendBase.destroy() method.

This patch adds 'type vnc' to vfb device sexpr for HVM guests. PV
guests already contain this entry in sexpr, e.g.
(device
(vfb
(vncunused 1)
...
(type vnc)
...
)
)
Some tools, such as libvirt, look for device/vfb/type in sexpr before
publishing VNC port. More importantly, this patch provides
consistency in vfb device sexpr between HVM and PV guests.

__volatile__ in most places) and ensure we use volatile keyword
wherever we have an asm stmt that produces outputs but has other
unspecified side effects or dependencies other than the
explicitly-stated inputs.
Also added volatile in a few places where its not strictly necessary
but where it's unlikely to produce worse code and it makes our
intentions perfectly clear.
The original problem this patch fixes was tracked down by Joseph
Cihula <joseph.cihula@intel.com>.

This patch reduces the number of CR8 intercept to a fraction of the
number of CR8 intercepts without. First, CR8 read intercepts are
completely disabled since the SVM vTPR is kept kept in sync with the
HVM vLAPIC TPR. Second, CR8 write intercepts are enabled and disabled
based upon certain conditions. Most of the time, CR8 write intercepts
are disabled. They are enabled only when there is a pending interrupt
that can't be delivered because of either the current ISR or TPR (aka
PPR) because this is the only time the TPR matters.
With this patch, the number of CR8 intercepts dropped from around
10,000,000 to around 6,000 during boot of Windows 2003 Server 64-bit
(this is a rough estimate).
