the kernel, so I can't use -kernel with it.

When giving KVM a slot of a size not on page boundary, it chokes. So let's
just round up the VGA BIOS size so nobody complains anymore and we don't need
to implement sub-page slots.

KVM can have an in-kernel pit or irqchip. While we don't implement it
yet, having a way for test for it (that always returns zero) will allow us
to reuse code in qemu-kvm that tests for it.

on_vcpu is a qemu-kvm function that will make sure that a specific
piece of code will run on a requested cpu. We don't need that because
we're restricted to -smp 1 right now, but those days are likely to end soon.
So for the benefit of having qemu-kvm share more code with us, I'm
introducing our own version of on_vcpu(). Right now, we either run
a function on the current cpu, or abort the execution, because it would
mean something is seriously wrong.
As an example code, I "ported" kvm_update_guest_debug to use it,
with some slight differences from qemu-kvm.
This is probably 0.12 material

Replace the use of atoi which is used for pattern parsing currently with
strtol. Atoi won't parse sedecimal pattern values (it always returns 0),
but qemu-iotests use such pattern values. Also reject every pattern
that is not a unsigned char as we pass the pattern to memset which
expect a bye value (despite having the pattern argument declared as int).
Based on an earlier patch by Stefan Weil which did not include the
error handling.

The alloc command in qemu-io is mostly useless currently. Instead of doing a
single call to bdrv_is_allocated, we must call bdrv_is_allocated in a loop
until we have found out for each requested sector if it is allocated or not
(bdrv_is_allocated returns a number of sectors that are known to be in the same
state as the first one, but it is not required to include all of them)
This changes the output format of the alloc command so that a change to the
expected output of qemu-iotests 019 is necessary once this is included.

Instead of storing the backing file in its own BlockDriverState, VMDK uses the
BlockDriverState of the raw image file it opened. This is wrong and breaks
functions that access the backing file or protocols. This fix replaces all
occurrences of s->hd->backing_* with bs->backing_*.
This fixes qemu-iotests failure in 020 (Commit changes to backing file).

Some KVM platforms don't support dirty logging yet, like IA64 and PPC,
so in order to still have screen updates on those, we need to fake it.
This patch just tells the getter function for dirty bitmaps, that all
pages within a slot are dirty when the slot has dirty logging enabled.
That way we can implement dirty logging on those platforms sometime when
it drags down performance, but share the rest of the code with dirty
logging capable platforms.
