Also split the isa bits into a separate source file, so we don't drag in
a dependency for isa-bus.o for machines which want ne2k_pci only.

Like isa_create_simple, but doesn't call qdev_init, so one can set
properties after creating and before initializing the device.

isa-bus owns the isa irqs now, so it can hand them out directly.
There is no need for the separate isa_connect_irqs step, drop it.
Also hard-code isa interrupts which can't be configured anyway.

Lot of ISA devices work at fixed addresses, so having iobase
as bus property doesn't make much sense. Devices which can
have different iobases will get a device property.
Also simply hard-code stuff which can't be configured anyway.

PCI device entries have to have a default version, not 2, because they are
used in the midle of other structures that can have _any_ version number.
We can't use proper versioning here until we have SubSections support.
Why we didn't noticed before? Because in a PC, the only device ported with
a version less that 2 is piix_pm, and for that one, default pci values are
right. If you use a virtio-console, you will see that its state it is not
loaded back.
Thanks to Amit Shah for reporting the problem and help debug the fix.

Doing this will make the vcpu ioctl be issued from the I/O thread, instead
of cpu thread. The correct behaviour is to call it from within the cpu thread,
as soon as we are ready to go.

The RTC emulation does not set the IRQ flags independent of the IRQ enable bits.
The original MC146818A datasheet from 1984 notes:
"flag bits in Register C [...] are set independent of the
state of the corresponding enable bits in Register B"
Similar sections can be found in newer documentation e.g. in rtc82885.
Qemu and Bochs set the IRQ flags only if they are enabled,
which breaks drivers polling on them.
The following patch corrects this for the update-ended-flag in Qemu only.
It does not fix the handling of the other flags.

Correct the logic of determining devices that supports
extended TxCB: only the 82557 do not support it.

Full coverage with properties and everything. You can add virtual usb
sticks this way now:
-drive if=none,id=pendrive,path=/some/where
-device usb-storage,drive=pendrive
-usbdevice disk:/path/to/image continues to work.
Other side effects:
usb storage is listed in 'info block' now.
kvm tree should be able to boot from usb via extboot (untested though).

Drop num_ports argument for usb_ohci_init_pci(), everybody
calls it with num_ports == 3, so it is pointless.
Convert ohci pci device into qdev.
TODO: convert non-pci ohci adapters.
You can add a OHCI USB Controller to your virtual pc now using
'-device pci-ohci'. Specifying a id is a good idea, so you can
attach usb devices to it, like this:
-device pci-ohci,id=ohci
-device usb-mouse,bus=ohci.0

Move usb code from vl.c to usb-bus.c and make it use the new data
structures added by qdev conversion. qemu usb core should be able
to handle multiple USB busses just fine now (untested though).

instead.
