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.)

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].

This preserves any data that the backing file had on a cluster when
doing a write to a subset of that cluster. These writes cause a
performance penalty on creating new clusters if a backing file is
present.

Reads to qcow files with backing files will fall through to the backing
file if there is no allocated cluster. As of this change, a write will
still trash the cluster and hide any data already present.
