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

c8c4a4d444 devices: Create Interrupt trait to abstract interrupt delivery
This commit anticipate the future need from having support for both
in kernel and userspace IOAPIC. The way to signal an interrupt from
the serial device will vary depending on the use case, but this should
be independent from the serial implementation itself.

That's why this patch provides a generic trait for the serial device
to call from, so that it can trigger interrupts independently from the
IOAPIC type chosen (in kernel vs userspace).

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.

1853b350ee cloud-hypervisor: Add devices crate
Based on the Firecracker devices crate from commit 9cdb5b2.

It is a trimmed down version compared to the Firecracker one, to remove
a bunch of pulled dependencies (logger, metrics, rate limiter, etc...).
