e1c09b66ba vmm: Replace device tree value when restoring DeviceManager 
When restoring replace the internal value of the device tree rather than
replacing the Arc<Mutex<DeviceTree>> itself. This is fixes an issue
where the AddressManager has a copy of the the original
Arc<Mutex<DeviceTree>> from when the DeviceManager was created. The
original restore path only replaced the DeviceManager's version of the
Arc<Mutex<DeviceTree>>. Instead replace the contents of the
Arc<Mutex<DeviceTree>> so all users see the updated version.

af770c814b block_util: provide and use AsyncAdaptor trait 
The observation is that the code in question was used to bridge
synchronized and asynchronized code.

We can group the functions for that purpose under an adaptor trait. To
limit the scope of locking, the users of the trait are required to
implement a method to return a MutexGuard for the underlying file.

This then allows us to use concrete types (QcowFile and Vhdx) in code,
which is easier to read than a bunch of traits.

No functional change intended.

a29e53e436 vmm: Move KVM clock saving to common Vm::restore() method 
Saving the KVM clock and restoring it is key for correct behaviour of
the VM when doing snapshot/restore or live migration. The clock is
restored to the KVM state as part of the Vm::resume() method prior to
that it must be extracted from the state object and stored for later use
by this method. This change simplifies the extraction and storage part
so that it is done in the same way for both snapshot/restore and live
migration.

00bb1ea1d5 tests: Enhance test for multiple PCI segments 
This commit enhances the integration test for multiple PCI segments
by:

(1) Enables the `test_virtio_fs_multi_segment` on AArch64.

(2) Adds a new integration test case for both x86_64 and AArch64 using
the direct kernel boot to test virtio-disk multiple PCI segments.
The test case does:
- Start a VM using direct kernel boot with 16 PCI segments and assign
the last PCI segment with a virtio-disk device.
- Check if the number of PCI host bridges equals to 16 after VM boots.
- Mount the virtio-disk device on the last PCI segment to the rootfs
and write/read data to the virtio-disk device.

90df54a245 aarch64: fdt: Create MSI mapping for PCI nodes 
Each PCI device under a root complex is uniquely identified by its
Requester ID (AKA RID). A Requester ID is a triplet of a Bus number,
Device number, and Function number.

MSIs may be distinguished in part through the use of sideband data
accompanying writes. In the case of PCI devices, this sideband data
may be derived from the Requester ID. A mechanism is required to
associate a device with both the MSI controllers it can address,
and the sideband data that will be associated with its writes to
those controllers.

This commit adds the `msi-map` property for PCI nodes, therefore
creating MSI mapping for each PCI device.
