Add basic flow control to stream. A stream slave may return short, indicating
that it is not capable of accepting any more data at the present time. Polling
or a callback can be used via the can_push() function to determine when the
slave can receive again.

This device is used for kvm unit tests,
currently it supports testing performance of ioeventfd.
Using updated kvm unittest, here's an example output:
mmio-no-eventfd:pci-mem 8796
mmio-wildcard-eventfd:pci-mem 3609
mmio-datamatch-eventfd:pci-mem 3685

Since commit 249d41720b (qdev: Prepare
"realized" property) setting realized = true would register the device's
VMStateDescription, but realized = false would not unregister it. Fix that.
Moving the code from unparenting also revealed that we were calling
DeviceClass::init through DeviceClass::realize as interim solution but
DeviceClass::exit still at unparenting time with a realized check.
Make this symmetrical by implementing DeviceClass::unrealize to call it,
while we're setting realized = false in the unparenting path.
The only other unrealize user is mac_nvram, which can safely override it.
Thus, mark DeviceClass::exit as obsolete, new devices should implement
DeviceClass::unrealize instead.

This fix the broken aliases, by renaming the devices.
So: * virtio-blk => virtio-blk-device.
* virtio-balloon => virtio-balloon-device.
* virtio-scsi => virtio-scsi-device.
All virtio-*-pci, virtio-*-s390, virtio-*-ccw didn't change.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
