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.

Modify `Cargo.toml` in each member crate to follow the dependencies
specified in root `Cargo.toml` file.

Otherwise, you just see output like "Error running command: Server
responded with an error: InternalServerError", which isn't very
helpful. The response body used to be include with the message, but
was removed when the Error enum was converted to thiserror.

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].

Previously, the API response was always written to stdout, but that may
not be appropriate for all clients.
The client can now control this behaviour as the client API returns the
response in the `Result`.
Fixes: #4703.

The existing API client only allows access to "VM" operations, so added
a new `simple_api_full_command_with_fds()` that allows access to "VMM"
operations too.
Also added a `simple_api_full_command()` to avoid having to specify the
file descriptors, in a similar manner to `simple_api_command()`.
Fixes: #4701.

Handle the case `body_offset` is `None` instead of calling `unwrap()`
which leads to a panic.

Breaks the receive loop of the API client when the VMM shuts down the
socket connection. A shutdown is indicated by the return value 0 of the
`recv()` system call.[^1][^2] This case was not handled before, so the
API client tried infinitely to receive more bytes and did not return.

Rust 2021 edition has a few improvements over the 2018 edition. Migrate
the project to 2021 edition by following recommended migration steps.
Luckily, the code itself doesn't require fixing.
Bump MSRV to 1.56 as it is required by the 2021 edition. Also fix the
clap build dependency to make Cloud Hypervisor build again.

This doesn't really affect the build as we ship a Cargo.lock with fixed
versions in. However for clarity it makes sense to use fixed versions
throughout and let dependabot update them.
