Pylint under 3.6 does not believe that Collection is subscriptable at
runtime. It is, making this a Pylint
bug. https://github.com/PyCQA/pylint/issues/2377

This patch creates a new type, QAPIExpression, which represents a parsed
expression complete with QAPIDoc and QAPISourceInfo.
This patch turns parser.exprs into a list of QAPIExpression instead,
and adjusts expr.py to match.
This allows the types we specify in parser.py to be "r

Introduce support for emulating CPUID for Xen HVM guests. It doesn't make
sense to advertise the KVM leaves to a Xen guest, so do Xen unconditionally
when the xen-version machine property is set.

Introduce support for one shot and periodic mode of Xen PV timers,
whereby timer interrupts come through a special virq event channel
with deadlines being set through:
1) set_timer_op hypercall (only oneshot)
2) vcpu_op hypercall for {set,stop}_{singleshot,periodic}_timer

This is simply when guest tries to register a vcpu_info
and since vcpu_info placement is optional in the minimum ABI
therefore we can just fail with -ENOSYS

The HVMOP_set_evtchn_upcall_vector hypercall sets the per-vCPU upcall
vector, to be delivered to the local APIC just like an MSI (with an EOI).
This takes precedence over the system-wide delivery method set by the
HVMOP_set_param hypercall with HVM_PARAM_CALLBACK_IRQ. It's used

This means handling the new exit reason for Xen but still
crashing on purpose. As we implement each of the hypercalls
we will then return the right return code.

It isn't strictly mandatory but Linux guests at least will only map
their grant tables over the dummy BAR that it provides, and don't have
sufficient wit to map them in any other unused part of their guest
address space. So include it by default for minimal surprise factor.
