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

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().

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

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.
I've tested this with PowerPC KVM and confirmed that it fixes virtio problems
when using non-TARGET_PAGE_SIZE pages in the guest.

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.
