legacy mouse event handlers are registered in the new core,
so they receive events submitted to the new input core.
legacy kbd_mouse_event() continues to use the old code paths.
So new-core event handlers wouldn't see events submitted via
kbd_mouse_event.
This leads to the constrain that we we must transition all
kbd_mouse_event() users first to keep things working. But
that is easier to handle than translating legacy mouse events
into new-core mouse events ;)

Transform absolute mouse events according to graphic_rotate.
Legacy input code does it for both absolute and relative events,
but the logic is broken for relative coordinates, so this is
most likely not used anyway.

Define input event types, using qapi. So we get nicely autogenerated
types for our input events. And when it comes to qmp support some day
things will be a lot easier.
Types are modeled after the linux input layer. There are separate
event types for each value. There is a sync to indicate the end
of a event group.
Mouse events are split into motion events (one for each axis) and
button events, which are grouped by sync.
Keyboard events are using the existing KeyValue type.

This makes use of @cpu_dt_id and related API in:
1. emulated XICS hypercall handlers as they receive fixed CPU indexes;
2. XICS-KVM to enable in-kernel XICS on right CPU;
3. device-tree renderer.
This removes @cpu_index fixup as @cpu_dt_id is used instead so QEMU monitor
can accept command-line CPU indexes again.
This changes kvm_arch_vcpu_id() to use ppc_get_vcpu_dt_id() as at the moment
KVM CPU id and device tree ID are calculated using the same algorithm.

Normally CPUState::cpu_index is used to pick the right CPU for various
operations. However default consecutive numbering does not always work
for POWERPC.
These indexes are reflected in /proc/device-tree/cpus/PowerPC,POWER7@XX
and used to call KVM VCPU's ioctls. In order to achieve this,
kvmppc_fixup_cpu() was introduced. Roughly speaking, it multiplies
cpu_index by the number of threads per core.
This approach has disadvantages such as:
1. NUMA configuration stays broken after the fixup;
2. CPU-targeted commands from the QEMU Monitor do not work properly as
CPU indexes have been fixed and there is no clear way for the user to
know what the new CPU indexes are.
This introduces a @cpu_dt_id field in the CPUPPCState struct which
is initialized from @cpu_index by default and can be fixed later
to meet the device tree requirements.
This adds an API to handle @cpu_dt_id.
This removes kvmppc_fixup_cpu() as it is not more needed, @cpu_dt_id
is calculated in ppc_cpu_realize().
This will be used later in machine code.

We currently size the msi window trap page according to the host's page

Existing code in the VROTATE, VSL and VSR macros for the Altivec rotate and shift
helpers uses a formula to compute a bit mask used to extract the rotate/shift
amount from the VRB register. What is desired is:
mask = (1 << (3 + log2(sizeof(element)))) - 1
but what is implemented is:
mask = (1 << (3 + (sizeof(element)/2))) - 1
This produces correct answers when "element" is uint8_t, uint16_t or uint_32t. But
it breaks down when element is uint64_t.
This patch corrects the situation. Since the mask is known at compile time, the
macros are changed to simply accept the mask as an argument.
Subsequent patches in this series will add double-word variants of rotates and
shifts and thus take advantage of this fix.
