Latest clippy version complains about our existing code for the
following reasons:
- trait objects without an explicit `dyn` are deprecated
- `...` range patterns are deprecated
- lint `clippy::const_static_lifetime` has been renamed to
`clippy::redundant_static_lifetimes`
- unnecessary `unsafe` block
- unneeded return statement
All these issues have been fixed through this patch, and rustfmt has
been run to cleanup potential formatting errors due to those changes.

Poor performance was observed when booting kernels with "console=ttyS0"
and the serial port disabled.
This change introduces a "null" console output mode and makes it the
default for the serial console. In this case the serial port
is advertised as per other output modes but there is no input and any
output is dropped.
Fixes: #163

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.

Some refactoring has taken place since the unit tests were written:
The read/write in BusDevice now take a base address and the interrupt
handling code has changed necessitating the need for a new TestInterrupt
struct.

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

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).

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.

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...).
