Sebastien Boeuf 950bd205c6 devices: Add userspace IOAPIC implementation ...

The goal for cloud-hypervisor is to keep the host safe. With this in
mind, we want to emulate as much as possible in userspace instead of
in kernel directly.

The IOAPIC is a good candidate to move from kernel to userspace, which
is why this commit introduces a userspace implementation of the IOAPIC
82093AA based on the documentation:
https://pdos.csail.mit.edu/6.828/2016/readings/ia32/ioapic.pdf

This code is inspired from the files devices/src/ioapic.rs and
devices/src/split_irqchip_common.rs from the crosvm codebase. The
reference version used being 6c1e23eee3065b3f3d6fc4fb992ac9884dbabf68.
