Instead of calling sysbus_init_mmio() with a null region,
create a dummy region using the memory API.

After NACKing a read operation, a raising SCL should not trigger a new
read from the slave. Introduce a new state which just waits for a stop
or start condition after NACK.

Reqrite bitbanging I2C implementation. New code improves stop/start
condition handling, and gives more accurate input line level.
Introduce intermediate abstraction layer for I2C bitbanging that
is not connected via a GPIO port.

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.
