Code in this crate is conditional on this feature so it necessary to
expose as a new feature and use that feature as a dependency when the
feature is enabled on the vmm crate.

The "dhat-heap" feature needs to be enabled inside the vmm crate as a
depenency from the top-level as there is build time check for that
feature inside the vmm crate.

Update the vhost-user-backend crate version used along with related
crates (vhost and virtio-queue.) This requires minor changes to the
types used for the memory in the backends with the use of the
BitmapMmapRegion type for the Bitmap implementation.

This patch bumps the following crates, including `kvm-bindings@0.7.0`*,
`kvm-ioctls@0.16.0`**, `linux-loader@0.11.0`, `versionize@0.2.0`,
`versionize_derive@0.1.6`***, `vhost@0.10.0`,
`vhost-user-backend@0.13.1`, `virtio-queue@0.11.0`, `vm-memory@0.14.0`,
`vmm-sys-util@0.12.1`, and the latest of `vfio-bindings`, `vfio-ioctls`,
`mshv-bindings`,`mshv-ioctls`, and `vfio-user`.
* A fork of the `kvm-bindings` crate is being used to support
serialization of various structs for migration [1]. Also, code changes
are made to accommodate the updated `struct xsave` from the Linux
kernel. Note: these changes related to `struct xsave` break
live-upgrade.
** The new `kvm-ioctls` crate introduced breaking changes for
the `get/set_one_reg` API on `aarch64` [2], so code changes are made to
the new APIs.
*** A fork of the `versionize_derive` crate is being used to support
versionize on packed structs [3].

Add a 'rate_limit_groups' field to VmConfig that defines a set of
named RateLimiterGroups.
When the 'rate_limit_group' field of DiskConfig is defined, all
virtio-blk queues will be rate-limited by a shared RateLimiterGroup.
The lifecycle of all RateLimiterGroups is tied to the Vm.
A RateLimiterGroup may exist even if no Disks are configured to use
the RateLimiterGroup. Disks may be hot-added or hot-removed from the
RateLimiterGroup.
When the 'rate_limiter' field of DiskConfig is defined, we construct
an anonymous RateLimiterGroup whose lifecycle is tied to the Disk.
This is primarily done for api backwards compatability. Importantly,
the behavior is not the same! This implementation rate_limits the
aggregate bandwidth / iops of an individual disk rather than the
bandwidth / iops of an individual queue of a disk.
When neither the 'rate_limit_group' or the 'rate_limiter' fields of
DiskConfig is defined, the Disk is not rate-limited.

vmm: Add igvm module and loader module
Add a separate module named igvm to the vmm crate
with definitions to parse and load igvm to the guest memory.

This patch adds igvm to the Vm config and params as well as
the command line argument to pass igvm file to load into
guest memory. The file must maintain the IGVM format.
The CLI option is featured guarded by igvm feature gate.
The IGVM(Independent Guest Virtual Machine) file format
is designed to encapsulate all information required to
launch a virtual machine on any given virtualization stack,
with support for different isolation technologies such as
AMD SEV-SNP and Intel TDX.
At a conceptual level, this file format is a set of commands created
by the tool that generated the file, used by the loader to construct
the initial guest state. The file format also contains measurement
information that the underlying platform will use to confirm that
the file was loaded correctly and signed by the appropriate authorities.
The IGVM file is generated by the tool:

The IGVM file is parsed by the following crates:

Partially revert 111225a2a5
and add the new dbus and pvpanic arguments.
As we are switching back to clap observe the following changes.
A few examples:
1. `-v -v -v` needs to be written as`-vvv`
2. `--disk D1 --disk D2` and others need to be written as `--disk D1 D2`.
3. `--option value` needs to be written as `--option=value.`
Change integration tests to adapt to the breaking changes.

The 'derive' feature of `zerocopy` crate now is optional and requires to
be enabled explicitly [1]. Also, a version bump on `acpi_tables` is
needed to reply on a single version of `zerocopy` to avoid compilation
errors.

This commit builds on top of the `Monitor::subscribe` function and
makes it possible to broadcast events published from `event-monitor`
over D-Bus.
The broadcasting functionality is enabled if the D-Bus API is enabled
and users who wish to also enable the file based `event-monitor` can do
so with the CLI arg `--event-monitor`.
