Add new control messages for vcpu hotplug events. Via the
xm vcpu-hotplug sub-program, vcpus in domains can be enabled/disabled
when CONFIG_HOTPLUG_CPU is enabled in the target domain's kernel.

sched.h, xen.h, schedule.c, dom0_ops.c, hypercall.h, smpboot.c, process.c:
Extend the CONFIG_HOTPLUG_CPU behavior down into the hypervisor.
Adds two SCHEDOPS (vcpu_down/vcpu_up) which set/clear VCPU flag VCPU_down.
The domain_runnable() check now looks at this flag and subsequently the
vcpu is not scheduled when VCPU_down is set.

Subject: [Xen-devel] [PATCH] _perform_err
the declaration of _perform_err needs at least three arguments
(exlcuding self), but gets onky called with two args at many
places. This messes up xend-debug.log.
Patch is against 2.0-testing, but applied cleanly to unstable
as well, when I checked last.

When xend starts, it fires off xcs. If you're running on a slow
machine its possible that xcs started but xend didnt wait long
enough to notice. The attached patch loops several times while
waiting for xcs to come up. It seems to be working here while the
original is not (slow machine here).
