5db4dede28 block_util, vhdx: vhdx crate integration with the cloud hypervisor
vhdx_sync.rs in block_util implements traits to represent the vhdx
crate as a supported block device in the cloud hypervisor. The vhdx
is added to the block device list in device_manager.rs at the vmm
crate so that it can automatically detect a vhdx disk and invoke the
corresponding crate.

4918c1ca7f block_util, vmm: Propagate error on QcowDiskSync creation
Instead of panicking with an expect() function, the QcowDiskSync::new
function now propagates the error properly. This ensures the VMM will
not panic, which might be the source of weird errors if only one thread
exits while the VMM continues to run.

1b87f332b0 block_util: Mark dirty pages manually with "VolatileSlice::as_ptr()"
As discussed in the working PR in the upstream vm-memory crate repo,
some special functions (e.g. return raw pointers to the wrapped guest
memory) require manual dirty page tracking from their users (e.g.the
VMM). One of the special functions is `VolatileSlice::as_ptr(), which is
used in our code base for supporting async block I/O. This patch
manually mark dirty for guest pages touched while reading from block
devices.

b5bcdbaf48 misc: Upgrade to use the vm-memory crate w/ dirty-page-tracking
As the first step to complete live-migration with tracking dirty-pages
written by the VMM, this commit patches the dependent vm-memory crate to
the upstream version with the dirty-page-tracking capability. Most
changes are due to the updated `GuestMemoryMmap`, `GuestRegionMmap`, and
`MmapRegion` structs which are taking an additional generic type
parameter to specify what 'bitmap backend' is used.

The above changes should be transparent to the rest of the code base,
e.g. all unit/integration tests should pass without additional changes.

b2e5dbaecb block_util, vmm: Add fixed VHD asynchronous implementation
This commit adds the asynchronous support for fixed VHD disk files.

It introduces FixedVhd as a new ImageType, moving the image type
detection to the block_util crate (instead of qcow crate).

It creates a new vhd module in the block_util crate in order to handle
VHD footer, following the VHD specification.

It creates a new fixed_vhd_async module in the block_util crate to
implement the asynchronous version of fixed VHD disk file. It relies on
io_uring.

060df69f07 block_util: Factorize common code for synchronous implementations
Since QCOW and RAW synchronous implementation are very close, it makes
sense to introduce some common functions that can be shared between
these two.

12e20effd7 block_util: Port synchronous QCOW file to AsyncIo trait
Based on the synchronous QCOW file implementation present in the qcow
crate, we created a new qcow_sync module in block_util that ports this
synchronous implementation to the AsyncIo trait.

The point is to reuse virtio-blk asynchronous implementation for both
synchronous and asynchronous backends.

da8ce25abf virtio-devices: Use asynchronous traits for virtio-blk io_uring
Based on the new DiskFile and AsyncIo traits, the implementation of
asynchronous block support does not have to be tied to io_uring anymore.
Instead, the only thing the virtio-blk implementation knows is that it
is using an asynchronous implementation of the underlying disk file.

30033bdaea block_util: Add new traits for handling disk files asynchronously
Both DiskFile and AsyncIo traits are introduced to allow all kind of
files (RAW, QCOW, VHD) to be able to handle asynchronous access to the
underlying file.
