This problem with this function is that it is not reversible - it is
impossible to know where things are registered and unregister them
exactly.  As there are no more users, we can remove it.

sysbus_init_mmio_cb() uses the destructive IO_MEM_UNASSIGNED to remove a
region.  Provide an alternative that calls an unmap callback, so the removal
may be done non-destructively.

Allow registering sysbus device memory using a MemoryRegion.  Once all users
are converted, sysbus_init_mmio() and sysbus_init_mmio_cb() will be removed.

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b.

Some not so obvious bits, slirp and Xen were left alone for the time

Sorry folks, but it has to be.  One more of these invasive qdev patches.

We have a serious design bug in the qdev interface:  device init
callbacks can't signal failure because the init() callback has no
return value.  This patch fixes it.

We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault.  This patch fixes it.

With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.

Record device property types, and provide a list of properties at device
registration time.

Add a "device" property type that holds a reference to annother device.
