causing circular header deps.

Just move the declaration of qemu_irq to the beginning of qemu-common.h
and leave the rest of files untouched. That also fixes the circular 
dependency.

I already have a patch that does this, so you can integrate it in your 
series
instead of this one.

No doubt it's more simpler way, but IMHO It's more of a hack than fixing
problem.
It works for now but doesn't alleviate problem with header nightmare in qemu,
where everything is included in qemu-common.h and everything includes it as
well.

Any way if majority prefer simple move, I'll drop this patch in favor of yours.
