hw/core/split-irq: Device that splits IRQ lines
In some board or SoC models it is necessary to split a qemu_irq line
so that one input can feed multiple outputs. We currently have
qemu_irq_split() for this, but that has several deficiencies:
* it can only handle splitting a line into two
* it unavoidably leaks memory, so it can't be used
in a device that can be deleted
Implement a qdev device that encapsulates splitting of IRQs, with a
configurable number of outputs. (This is in some ways the inverse of
the TYPE_OR_IRQ device.)
