61e57e1cb1 misc: Further improve imports styling
By introducing `imports_granularity="Module"` format strategy,
effectively groups imports from the same module into one line or block,
improving maintainability and readability.

88a9f79944 misc: Adapt consistent import style formatting
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.

a69d8c63b3 vmm: speed up JSON load when reading snap files
We found that it's slow to load JSON when reading snap files. As
described in [1], using from_slice instead of from_reader can fix
this.

Also, fix the error type being returned.

5b3bcfa233 vm-migration: Snapshot should have a unique SnapshotDataSection
There's no reason to carry a HashMap of SnapshotDataSection per
Snapshot. And given we now provide at most one SnapshotDataSection per
Snapshot, there's no need to keep the id part of the SnapshotDataSection
structure.

cefbf6b4a3 vmm: guest_debug: Mark coredump functionality x86_64 only
The coredump functionality is only implemented for x86_64 so it should
only be compiled in there.

90034fd6ba vmm: add GuestDebuggable trait
It's useful to dump the guest, which named coredump so that crash
tool can be used to analysize it when guest hung up.

Let's add GuestDebuggable trait and Coredumpxxx error to support
coredump firstly.

10676b74dc vmm: Split VM config and VM state for snapshot/restore
In order to allow for human readable output for the VM configuration, we
pull it out of the snapshot, which becomes effectively the list of
states from the VM. The configuration is stored through a dedicated file
in JSON format (not including any binary output).

Having the ability to read and modify the VM configuration manually
between the snapshot and restore phases makes debugging easier, as well
as empowers users for extending the use cases relying on the
snapshot/restore feature.

8038161861 vmm: Get and set clock during pause and resume operations
In order to maintain correct time when doing pause/resume and
snapshot/restore operations, this patch stores the clock value
on pause, and restore it on resume. Because snapshot/restore
expects a VM to be paused before the snapshot and paused after
the restore, this covers the migration use case too.
