Fills out support for the pci assignment API.  Added:

PCIINTxRoute ich9_route_intx_pin_to_irq(void *opaque, int pirq_pin)

Add calls to pci_bus_fire_intx_routing_notifier() when routing changes
are made.

Starting with release 1.4 we have a fully functional q35 machine type,
i.e. "qemu -M q35" JustWorks[tm].  Update machine type names to reflect
that:

  * pc-1.4 becomes pc-i440fx-1.4
  * q35-next becomes pc-q35-1.4

The pc-1.3 (+older) names are maintained for compatibility reasons.
For the same reason the "pc" and "q35" aliases are kept.  pc-piix-1.4
continues to be the default machine type, again for compatibility
reasons.

Also updated the description (shown by "qemu -M ?") with host bridge
name, south bridge name and chipset release year.

pc q35 based chipset emulator to support pci express natively. Based on
Anthony Liguori's suggestion, the machine name is 'q35-next', with an alias
of 'q35'. At this point, there are no compatibility guarantees. When the
chipset stabilizes more, we will begin to version the machine names.

Major features which still need to be added:

-Migration support (mostly around ahci)
-ACPI hotplug support (pcie hotplug support is working)
-Passthrough support
