Marc-André Lureau 0457762e9e irq: add per-IRQ observer to fix qemu_irq_intercept_in leak ...

qemu_irq_intercept_in() saves original IRQ handlers by allocating
new QOM objects, which are never freed. On a PC machine, this leaks
IRQ objects (one per IOAPIC pin) on every qtest run.

Rather than tracking allocations to free later, avoid them: add an
"observer" field to IRQState, called by qemu_set_irq() after the
real handler. Interception sets the observer instead of rewriting
handlers, so there's nothing to save and nothing to leak.

Fix qemu_notirq() to route through qemu_set_irq() so inverted IRQs
trigger observers too. Drop the LSan suppression.
