1fc6d50f3e misc: Make Bus::write() return an Option<Arc<Barrier>>
This can be uses to indicate to the caller that it should wait on the
barrier before returning as there is some asynchronous activity
triggered by the write which requires the KVM exit to block until it's
completed.

This is useful for having vCPU thread wait for the VMM thread to proceed
to activate the virtio devices.

See #1863

15025d71b1 devices, vm-device: Move BusDevice and Bus into vm-device
This removes the dependency of the pci crate on the devices crate which
now only contains the device implementations themselves.

ae66a44d26 vmm: Support both reset and shutdown
Add a 2nd EventFd to the VM to control resetting (rebooting) the VM this
supplements the EventFd used for managing shutdown of the VM.

The default behaviour on i8042 or triple-fault based reset is currently
unchanged i.e. it will trigger a shutdown.

In order to support restarting the VM it was necessary to make start()
function take a reference to the config.

9caad7394d build, misc: Bump vmm-sys-util dependency
The structure of the vmm-sys-util crate has changed with lots of code
moving to submodules.

This change adjusts the use of the imported structs to reference the
submodules.

Fixes: #145

8173e1ccd7 devices: Extend the Bus trait to carry the device range base
With the range base for the IO/MMIO vm exit address, a device with
multiple ranges has all the needed information for resolving which of
its range the exit is coming from

Fixes: #87

342bdc3619 devices: Add support for i8042 reset device
Introduce emulation of i8042 device to allow the guest to stop the
VM by issuing a reset event.

The device has been copied over from the Crosvm code base, relying on
the commit 0268e26e1ac9e09aa51d733482c5df139cd8d588.
