valgrind reports a lot more memory leaks which are related to
function qemu_allocate_irqs. In many cases, its return value
should be free'd. g_malloc / g_free can be avoided by adding
a new function

void qemu_init_irqs(qemu_irq_handler handler, void *opaque,
                     qemu_irq *irqs, int n);

If this is ok, I'll send patches which add and use the new
function instead of qemu_allocate_irqs, too.
