To simplify writing native VirtIO drivers for Genode add helper classes representing VirtIO device and queue. The queue implementation should be platform independant. The device abstraction however is closely tied to the VirtIO transport being used (PCI/MMIO). Both PCI and MMIO implementations expose the same public API so the actual driver logic should be the same regardless of which transport is used. Its also important to note that the PCI version of Virtio::Device currently does not support MSI-X interrupts. Unfortunately my kowledge about PCI bus is very limited and my main area of interest was to get VirtIO drivers working on virt_qemu ARM/Aarch64 platform. As such all the VirtIO drivers I plan to submit will work with PCI bus, but might not use some extended capabilities. Ref #3825
