Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.
By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

As per VirtIO spec 1.2 section 5.2.6, the `status` field is a byte, not
u32. cloud-hypervisor writes an `u32` to guest memory, which
accidentally zeros out the following 3 bytes, and may corrupt guest OS
internal state.

In 42e9632c53 a fix was made to address a
typo in the taplo configuration file. Fixing this typo indicated that
many Cargo.toml files were no longer adhering to the formatting rules.
Fix the formatting by running `taplo fmt`.

Impose a limit on the maximum nesting of file formats that can open more
files. For example, a qcow2 file can have a backing file, which could be
another qcow2 file with a backing file (or even the same file as the
original), potentially causing unbounded recursion.

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.
Signed-off-by: Rob Bradford <rbradford@rivosinc.com>
Replace the specific Bitmap implementation from the type signature used
for functions that take memory. This allows more flexibility when using
these functions in particular when these functions are used by the
vhost-user-block backend. An updated vhost-user-backend crate requires
extra constraints on the Bitmap implementation used (it must support
BitmapReplace which AtomicBitmap does not.)

Prefix field with an _ to indicate that this is intentionally unused.

With the nightly toolchain (2024-02-18) cargo check will flag up
redundant imports either because they are pulled in by the prelude on
earlier match.
Remove those redundant imports.

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].
