Calls to the kvm crate have been replaced by calls to hypervisor and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.

Move GuestAddress and GuestMemory to a new crate for VM memory. This
will make separating sys_util and crosvm independent making it easier
to use sys_util functions outside of crosvm.

Add methods for making RunnableVcpus, requesting vmexits on a vcpu,
injecting interrupts, and setting I/O data. This code is unchanged
from the kvm crate.
A new Vcpu::handle_io_events method delivers pending IO events. This is
for hypervisors that handle IO events in userspace. On KVM it's a
no-op.

Modified ioapic implementation for the hypervisor abstraction layer.
This implementation has the same functionality and tests as the existing
one, but accepts a vec of resample_events instead of a GsiRelay. It also
takes a list of irqfds instead of creating them itself.
This will be used by the KvmSplitIrqChip, and will eventualy be modified
again to support an ApicBus when we want to support a UserspaceIrqChip.

Copied and slightly modified pic implementation in the irqchip
submodule. It uses the PicState defined in the hypervisor crate and has
a register_resample_events function instead of a register_relay
function.
Some function signatures have been slightly changed to take &self and
&mut self where before they would take a PicState. This was done so
that the Pic struct itself would be the only object that needs access
to the resample_events rather than each PicState needing it's own copy
or clone.
This will later be used by the the KvmSplitIrqChip.
