Rob Bradford c622278030 config, device_manager: Add support for disabling io_uring for testing

Rob Bradford fb70baece0 tests: Make integration test use vhost_user_{net,block} binaries 
With the removal of vhost-user self-spawning support we should migrate

from the cloud-hypervisor binary itself.

Rob Bradford 3ac9b6c404 vmm: Implement live migration 
Now the VM is paused/resumed by the migration process itself.

0. The guest configuration is sent to the destination
1. Dirty page log tracking is started by start_memory_dirty_log()
2. All guest memory is sent to the destination
3. Up to 5 attempts are made to send the dirty guest memory to the
   destination...
4. ...before the VM is paused
5. One last set of dirty pages is sent to the destination
6. The guest is snapshotted and sent to the destination
7. When the migration is completed the destination unpauses the received
   VM.

Rob Bradford 11a69450ba vm-migration, vmm: Send configuration in separate step 
Prior to sending the memory the full state is not needed only the
configuration. This is sufficient to create the appropriate structures
in the guest and have the memory allocations ready for filling.

Update the protocol documentation to add a separate config step and move
the state to after the memory is transferred. As the VM is created in a
separate step to restoring it the requires a slightly different
constructor as well as saving the VM object for the subsequent commands.

Rob Bradford c62e409827 memory_manager: Generate a MemoryRangeTable for dirty ranges 
In order to do this we must extend the MemoryManager API to add the
ability to specify the tracking of the dirty pages when creating the
userspace mappings and also keep track of the userspace mappings that
have been created for RAM regions.

Currently the dirty pages are collected into ranges based on a block
level of 64 pages. The algorithm could be tweaked to create smaller
ranges but for now if any page in the block of 64 is dirty the whole
block is added to the range.

Rob Bradford 46e736973e hypervisor: kvm: Correctly share VmmOps between Kvm{Vm,Vcpu} 
Cloning the ArcSwapOption (like the ArcSwap) does not act like a
.clone() on an Arc, instead an entirely new ArcSwap is created with the
same contents. To correctly share the ArcSwap needs to be placed inside
an Arc.

See: https://github.com/vorner/arc-swap/commit/2433d5719be341dc520a8bb93d9d3ce7f141a80d#diff-6c6d94533c44c19bd1416ef17bad1a878e63dca6e98d59181228fbe8f967c62bR6

Due to this being wrongly used ::clone() was removed from
ArcSwap/ArcSwapOption in 1.0.0.

Rob Bradford ca60adda70 vmm: Add support for sending and receiving migration if VM is paused 
This is tested by:

Source VMM:

target/debug/cloud-hypervisor --kernel ~/src/linux/vmlinux \
--pmem file=~/workloads/focal.raw --cpus boot=1 \
--memory size=2048M \
--cmdline"root=/dev/pmem0p1 console=ttyS0" --serial tty --console off \
--api-socket=/tmp/api1 -v

Destination VMM:

target/debug/cloud-hypervisor --api-socket=/tmp/api2 -v

And the following commands:

target/debug/ch-remote --api-socket=/tmp/api1 pause
target/debug/ch-remote --api-socket=/tmp/api2 receive-migration unix:/tmp/foo &
target/debug/ch-remote --api-socket=/tmp/api1 send-migration unix:/tmp/foo
target/debug/ch-remote --api-socket=/tmp/api2 resume

The VM is then responsive on the destination VMM.

Due to a known limitation in OpenAPITools/openapi-generator tool,
it's impossible to send go zero types, like false and 0 to

`omitempty` from the json tag.
