Alexander Graf 61de36761b qdev: Keep global allocation counter per bus 
When we have 2 separate qdev devices that both create a qbus of the
same type without specifying a bus name or device name, we end up
with two buses of the same name, such as ide.0 on the Mac machines:

  dev: macio-ide, id ""
    bus: ide.0
      type IDE
  dev: macio-ide, id ""
    bus: ide.0
      type IDE

If we now spawn a device that connects to a ide.0 the last created
bus gets the device, with the first created bus inaccessible to the
command line.

After some discussion on IRC we concluded that the best quick fix way
forward for this is to make automated bus-class type based allocation
count a global counter. That's what this patch implements. With this
we instead get

  dev: macio-ide, id ""
    bus: ide.1
      type IDE
  dev: macio-ide, id ""
    bus: ide.0
      type IDE

on the example mentioned above.

This also means that if you did -device ...,bus=ide.0 you got a device
on the first bus (the last created one) before this patch and get that
device on the second one (the first created one) now.  Breaks
migration unless you change bus=ide.0 to bus=ide.1 on the destination.

This is intended and makes the bus enumeration work as expected.

As per review request follows a list of otherwise affected boards and
the reasoning for the conclusion that they are ok:

   target      machine         bus id              times
   ------      -------         ------              -----

   aarch64     n800            i2c-bus.0           2
   aarch64     n810            i2c-bus.0           2
   arm         n800            i2c-bus.0           2
   arm         n810            i2c-bus.0           2

-> Devices are only created explicitly on one of the two buses, using
   s->mpu->i2c[0], so no change to the guest.

   aarch64     vexpress-a15    virtio-mmio-bus.0   4
   aarch64     vexpress-a9     virtio-mmio-bus.0   4
   aarch64     virt            virtio-mmio-bus.0   32
   arm         vexpress-a15    virtio-mmio-bus.0   4
   arm         vexpress-a9     virtio-mmio-bus.0   4
   arm         virt            virtio-mmio-bus.0   32

-> Makes -device bus= work for all virtio-mmio buses.  Breaks
   migration.  Workaround for migration from old to new: specify
   virtio-mmio-bus.4 or .32 respectively rather than .0 on the
   destination.

   aarch64     xilinx-zynq-a9  usb-bus.0           2
   arm         xilinx-zynq-a9  usb-bus.0           2
   mips64el    fulong2e        usb-bus.0           2

-> Normal USB operation not affected. Migration driver needs command
   line to use the other bus.

   x86_64      isapc           ide.0               2

   ppc64       prep            ide.0               2

-> Makes -device bus= work for all IDE buses.  Breaks migration.
   Workaround for migration from old to new: specify ide.1 rather than
   ide.0 on the destination.
