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
to find a driver)."
While this is valid, many versions of X will get confused by it.
Class major number of 0 gets treated as a possibly prehistoric VGA
device, and then the autoconfig logic gets confused trying to figure
out whether the virtio console or the pv vga device are the real VGA.
We should really set a proper class ID. 0x0780 (serial / other) seems
most appropriate. This shouldn't require any kernel changes, the
modalias for virtio looks like:
alias: pci:v00001AF4d*sv*sd*bc*sc*i*
so won't care what the base class or subclass are.
It shows up in the guest as:
00:05.0 Communication controller: Qumranet, Inc. Virtio console
A new qdev type is introduced to allow devices using the old class
to be created for compatibility with qemu-0.10.x.

destroy_nic() requires that NICInfo::private by a PCIDevice pointer,
but then goes on to require that the same pointer matches
VLANClientState::opaque.
That is no longer the case for virtio-net since qdev and wasn't
previously the case for rtl8139, ne2k_pci or eepro100.
Make the situation a lot more clear by maintaining a VLANClientState
pointer in NICInfo.

Yes, the device name is redundant. Only for drivers converted
to qdev already though. Once all drivers are converted we can
and should kill it.

The only purpose DeviceType serves is creating a linked list of
DeviceInfo structs. This removes DeviceType and add a next field to
DeviceInfo instead, so the DeviceInfo structs can be changed that way.
Elimitates a pointless extra level of indirection.

BusInfo is filled with name and size (pretty much like I did for
DeviceInfo as well). There is also a function pointer to print
bus-specific device information to the monitor. sysbus is hooked
up there, I've also added a print function for PCI.
Device creation is slightly modified as well: The device type search
loop now also checks the bus type while scanning the list instead of
complaining thereafter in case of a mismatch. This effectively gives
each bus a private namespace for device names.
