Virtio: added drivers for PCI busses, bus manager and block device.
* the Virtio PCI bus driver exposes a Virtio controller to the Virtio bus manager,
which in turn exposes a Virtio device consumed by Virtio drivers. Drivers follow the
new driver model.
* virtio_block handles Virtio block devices under disk/virtual/virtio_block/x/raw.
* Here is the Qemu command line option for Virtio disk devices:
-drive file=haiku.image,if=virtio
* the PCI bus driver currently supports only legacy interrupts (no MSI(-X) yet).
* There is room for improvements in the bus manager:
- it notifies the host for each queued request, which isn't optimal.
- transfer descriptors should probably be simply preallocated (they are nicely
leaked at the moment).
- indirect descriptors are not supported yet.
and in the block driver:
- get the id of the disk.
- implements flushing the cache.
- improves dma restrictions.
- do_io() should use a page for header descriptors instead of malloc(), which
could cross boundaries.
* The device manager tries to guess the driver based on the PCI device type, this
implies having to declare the "busses/virtio" path for each possible type
provided by Virtio. Thus future driver additions might require patching the device
manager.
* virtio.h is still private, the API is subject to changes.
* virtio_pci.h, virtio_blk.h, virtio_ring.h are copied unchanged from FreeBSD.
