Allow guests to use the MSI capability in devices that support it. Emulate the MSI capability, which is simpler than MSI-X as it doesn't rely on external tables. Reuse most of the MSI-X code. Guests may choose between MSI and MSI-X at runtime since we present both capabilities, but they cannot enable MSI and MSI-X at the same time (forbidden by PCI).
