We need to rely on the latest kvm-ioctls version to benefit from the
recent addition of unregister_ioevent(), allowing us to detach a
previously registered eventfd to a PIO or MMIO guest address.
Because of this update, we had to modify the current constraint we had
on the vmm-sys-util crate, using ">= 0.1.1" instead of being strictly
tied to "0.2.0".
Once the dependency conflict resolved, this commit took care of fixing
build issues caused by recent modification of kvm-ioctls relying on
EventFd reference instead of RawFd.

The command "cargo build --no-default-features" does not recursively
disable the default features across the workspace. Instead add an acpi
feature at the top-level, making it default, and then make that feature
conditional on all the crate acpi features.

Add an I/O port "device" to handle requests from the kernel to shutdown
or trigger a reboot, borrowing an I/O used for ACPI on the Q35 platform.
The details of this I/O port are included in the FADT
(SLEEP_STATUS_REG/SLEEP_CONTROL_REG/RESET_REG) with the details of the
value to write in the FADT for reset (RESET_VALUE) and in the DSDT for
shutdown (S5 -> 0x05)

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.

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.

Some refactoring has taken place since the unit tests were written:
The read/write in BusDevice now take a base address and the interrupt

struct.

When resolving an IO address to a device, return the range base address,
the offset, and the device itself.
This is needed for devices with multiple IO regions to find out which
region an IO/MMIO exit is coming from.
We also use this change as an opportunity to rename get_device to
resolve as we're doing more than just getting a device.

The goal for cloud-hypervisor is to keep the host safe. With this in
mind, we want to emulate as much as possible in userspace instead of
in kernel directly.
The IOAPIC is a good candidate to move from kernel to userspace, which
is why this commit introduces a userspace implementation of the IOAPIC
82093AA based on the documentation:
https://pdos.csail.mit.edu/6.828/2016/readings/ia32/ioapic.pdf
This code is inspired from the files devices/src/ioapic.rs and
devices/src/split_irqchip_common.rs from the crosvm codebase. The
reference version used being 6c1e23eee3065b3f3d6fc4fb992ac9884dbabf68.

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).
