23929f41a7 vfio: Don't override MSI Enable bit through VFIO ioctl
This commit ensures device's PCI config space is being written after
MSI/MSI-X interrupts have been enabled/disabled. In case of MSI, when
the interrupts are enabled through VFIO (using VFIO_DEVICE_SET_IRQS),
the MSI Enable bit in the MSI capability structure found in the PCI
config space is disabled by default. That's why when the guest is
enabling this bit, we first need to enable the MSI interrupts with
VFIO through VFIO_DEVICE_SET_IRQS ioctl, and only after we can write
to the device region to update the MSI Enable bit.

Fixes #460

08258d5dad vfio: pci: Allow multiple devices to be passed through
The KVM_SET_GSI_ROUTING ioctl is very simple, it overrides the previous
routes configuration with the new ones being applied. This means the
caller, in this case cloud-hypervisor, needs to maintain the list of all
interrupts which needs to be active at all times. This allows to
correctly support multiple devices to be passed through the VM and being
functional at the same time.

669d9a8ae8 vhost_user_backend: fix memory region offsetting
The way in which offsets are currently use in memory regions is
derived from QEMU's contrib/libvhost-user, but while this one works
mainly by translating vmm va's to local va's, vm-memory expects us to
use proper guest addresses and thus, define memory regions that
actually match the guest's memory disposition.

With this change, we create the memory regions with the proper length
and offsets, extend AddrMapping to store the guest physical address,
and use the latter instead of offset in vmm_va_to_gpa().

0f21781fbe cargo: Bump the kvm and vmm-sys-util crates
Since the kvm crates now depend on vmm-sys-util, the bump must be
atomic.
The kvm-bindings and ioctls 0.2.0 and 0.4.0 crates come with a few API
changes, one of them being the use of a kvm_ioctls specific error type.
Porting our code to that type makes for a fairly large diff stat.
