Change default PCI class of virtio-blk to PCI_CLASS_STORAGE_SCSI

Windows virtio driver cannot pass DTM (certification) tests while the
storage class is PCI_CLASS_STORAGE_UNKNOWN.

A new qdev type is introduced to allow devices using the old class
to be created for compatibility with qemu-0.10.x....

Change default PCI class of virtio-console to PCI_CLASS_SERIAL_OTHER

We're using PCI_CLASS_DISPLAY_OTHER now, but qemu-kvm.git is using
PCI_CLASS_OTHERS because:

"As a PCI_CLASS_DISPLAY_OTHER, it reduces primary display somehow on
   Windows XP (possibly Windows disables acceleration since it fails...

qemu/virtio: mark msi vectors used on load

Usage of msi vectors is controlled by the guest and so needs to be
restored on load. Do this for msi vectors used by the virtio device.

qdev: update pci device registration.

Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch
of parameters. Also adds config_read and config_write callbacks to
PCIDeviceInfo, so drivers needing these can be converted to the qdev
device API too....

Revert "Introduce reset notifier order"

This reverts commit 8217606e6edb49591b4a6fd5a0d1229cebe470a9 (and
updates later added users of qemu_register_reset), we solved the
problem it originally addressed less invasively.

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...

Rename pci_register_io_region() to pci_register_bar()

This function is used to manage a PCI BAR, so make the more generic
pci_register_io_region() available to other uses.

Hardware convenience library

The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target...
