Calls to the kvm crate have been replaced by calls to hypervisor and
devices::irqchip. Plugin is unchanged and still KVM-specific.
x86 creates and configures vcpus on the vcpu thread instead of the main
thread.
Code that still depends on kvm or kvm_sys:
- crosvm_plugin, plugin, and protos use kvm and kvm_sys if built with
the plugin feature
- devices::VfioGroup does a kvm_sys ioctl
- devices::irqchip and hypervisor use kvm_sys. hypervisor uses
kvm::Cap and kvm::CpuId internally for now.

For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.

Implemented the remaining IrqChip trait functions for the
KvmKernelIrqChip, including register/unregister_irq_event and irq
routing functions.
Added some irqchip tests for setting irq routes and servicing irq lines.
Also added tests for registering irq events.

This new module contains the irqchip trait and it's implementations. The
irqchips will work with the new hypervisor crate to abstract the
interaction between crosvm and kvm.
This just defines the irqchip trait and an empty implementation of the
KvmKernelIrqChip.
