From: Marc Zyngier <marc.zyngier@xxxxxxx>
The ARM GIC emulation needs to be told the number of interrupts
it has to support. As commit 1c262fa1dc7bc ("kvm tools: irq: make
irq__alloc_line generic") made the interrupt counter private,
add a new accessor returning the number of interrupt lines we've
allocated so far.
