qdev-ify virtio-blk.

First user of the new drive property. With this patch applied host
and guest config can be specified separately, like this:

-drive if=none,id=disk1,file=/path/to/disk.img
  -device virtio-blk-pci,drive=disk1

You can set any property for virtio-blk-pci now. You can set the pci...

qemu/virtio: virtio support for many interrupt vectors

Extend virtio to support many interrupt vectors, and rearrange code in
preparation for multi-vector support (mostly move reset out to bindings,
because we will have to reset the vectors in transport-specific code)....

virtio: add support for indirect ring entries

Support a new feature flag for indirect ring entries. These are ring
entries which point to a table of buffer descriptors.

The idea here is to increase the ring capacity by allowing a larger
effective ring size whereby the ring size dictates the number of...

Fix oops on 2.6.25 guest (Rusty Russell)

I believe this is behind the following:
https://bugs.edge.launchpad.net/ubuntu/jaunty/+source/linux/+bug/331128

virtio_pci in 2.6.25 didn't do feature negotiation correctly: it acked every
bit. Fortunately, we can detect this....

Add and use #defines for PCI device classes

This patch adds and uses #defines for PCI device classes and subclases,
using a new pci_config_set_class() function, similar to the recently
added pci_config_set_vendor_id() and pci_config_set_device_id().

Change since v1: fixed compilation of hw/sun4u.c...

Make struct iovec universally available

Vectored IO APIs will require some sort of vector argument. It makes sense to
use struct iovec and just define it globally for Windows.

Remove TARGET_PAGE_SIZE from virtio interface (Hollis Blanchard)

TARGET_PAGE_SIZE should only be used internal to qemu, not in guest/host
interfaces. The virtio frontend code in Linux uses two constants (PFN shift
and vring alignment) for the interface, so update qemu to match....

Virtio core support

This patch adds core support for VirtIO. VirtIO is a paravirtualization
framework that has been in Linux since 2.6.21. A PCI transport has been
available since 2.6.25. Network drivers are also available for Windows.
