vmm: interrupt: fix msi mask irq causing kernel panic on AMD
When mask a msi irq, we set the entry.masked to be true, so kvm
hypervisor will not pass the gsi to kernel through KVM_SET_GSI_ROUTING
ioctl which update kvm->irq_routing. This will trigger kernel
panic on AMD platform when the gsi is the largest one in kernel

To solve this problem, move route.disable() before set_gsi_routes() to
remove the gsi from irqfds.items first.
This problem only exists on AMD platform, 'cause on Intel platform
kernel just return when update irte while it only prints a warning on
AMD.
Also, this patch adjusts the order of enable() and set_gsi_routes() in
unmask(), which should do no harm.

vmm: Ensure that PIO and MMIO exits complete before pausing
As per this kernel documentation:
For KVM_EXIT_IO, KVM_EXIT_MMIO, KVM_EXIT_OSI, KVM_EXIT_PAPR, KVM_EXIT_XEN,
KVM_EXIT_EPR, KVM_EXIT_X86_RDMSR and KVM_EXIT_X86_WRMSR the corresponding
operations are complete (and guest state is consistent) only after userspace
has re-entered the kernel with KVM_RUN. The kernel side will first finish
incomplete operations and then check for pending signals.
The pending state of the operation is not preserved in state which is
visible to userspace, thus userspace should ensure that the operation is
completed before performing a live migration. Userspace can re-enter the
guest with an unmasked signal pending or with the immediate_exit field set
to complete pending operations without allowing any further instructions
to be executed.
Since we capture the state as part of the pause and override it as part
of the resume we must ensure the state is consistent otherwise we will
lose the results of the MMIO or PIO operation that caused the exit from
which we paused.
Fixes: #3658

vmm: Avoid deadlock between virtio device activation and vcpu pausing
Ensure all pending virtio activations (as triggered by MMIO write on the vCPU threads leading to a barrier wait) are completed before pausing the vCPUs as otherwise there will a deadlock with the VMM waiting for the vCPU to acknowledge it's pause and the vCPU waiting for the VMM to activate the device and release the barrier.

vmm: Send FDs across unix socket for migration when in local mode
When in local migration mode send the FDs for the guest memory over the socket along with the slot that the FD is associated with. This removes the requirement for copying the guest RAM and gives significantly faster live migration performance (of the order of 3s to 60ms).

When using this code on the Kata Containers side we'd be hit by a non expected behaviour of cloud-hypervisor, as even when using a different method to initialise the `tuntap` device the code would be treated as if using `--net tap` (which is a valid use-case).
