crate it is no longer compiled differently based on the mmio or pci

Move NetQueuePair and the related NetCounters into the net_util crate.
This means that the vhost_user_net crate now no longer depends on
virtio-devices and so does not depend on the pci, qcow or other similar
crates. This significantly simplifies the build chain for this backend.

By moving the code for opening the two RX and TX queues into a shared
location we are starting to remove the requirement for the
vhost-user-net backend to depend on the virtio-devices crate which in of
itself depends on many other crates that are not necessary for the
backend to function.

This commit store balloon size to MemoryConfig.
After reboot, virtio-balloon can use this size to inflate back to
the size before reboot.
Signed-off-by: Hui Zhu <teawater@antfin.com>
The implementation of the virtio-balloon was slightly wrong as it was
generating the GPA (Guest Physical Address) from the PFN (Page Frame
Number) which was a u32. That means the GPA was created as a u32, and
later a cast was done to extend it to a u64 type. Unfortunately, by
doing so, the GPA was wrong if the value was supposedly more than 32
bits.
That's why the PFN is casted into a u64 before the GPA is generated,
which creates the GPA on 64 bits directly.
Additionally, this patch simplifies the process_queue() function,
relying on multiple vm-memory helpers.

This commit adds a Jenkins stage for AArch64 integration test,

The compiled AArch64 linux kernel by running `make` is in PE format
instead of vmlinux, vmlinux.pvh and bzImage format. Therefore we
need to add integration test for this case.

This commit adds supporting components and code for enabling the
AArch64 integration tests, including:
1. A Linux kernel config file to build kernel on AArch64 machines.
2. Refactoring the `run_integration_test.sh` to architecture
specific scripts for readability.

Remove the vmm dependency from vhost_user_block and vhost_user_net where
it was existing to use config::OptionParser. By moving the OptionParser
to its own crate at the top-level we can remove the very heavy
dependency that these vhost-user backends had.

In order to move the hypervisor specific parts of the VM exit handling
path, we're defining a generic, hypervisor agnostic VM exit enum.
This is what the hypervisor's Vcpu run() call should return when the VM
exit can not be completely handled through the hypervisor specific bits.
For KVM based hypervisors, this means directly forwarding the IO related
exits back to the VMM itself. For other hypervisors that e.g. rely on the
VMM to decode and emulate instructions, this means the decoding itself
would happen in the hypervisor crate exclusively, and the rest of the VM
exit handling would be handled through the VMM device model implementation.
