Replace qemu_allocate_irqs(foo, bar, 1)[0]
with qemu_allocate_irq(foo, bar, 0).
This avoids leaking the dereferenced qemu_irq *.

There are currently three types of object_property_add_link() callers:
1. The link property may be set at any time.
2. The link property of a DeviceState instance may only be set before
realize.
3. The link property may never be set, it is read-only.
Something similar can already be achieved with
object_property_add_str()'s set() argument. Follow its example and add
a check() argument to object_property_add_link().
Also provide default check() functions for case #1 and #2. Case #3 is
covered by passing a NULL function pointer.

Some object_property_add_link() callers expect property deletion to
unref the link property object. Other callers expect to manage the
refcount themselves. The former are currently broken and therefore leak
the link property object.
This patch adds a flags argument to object_property_add_link() so the
caller can specify which refcount behavior they require. The new
OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be
unreferenced when the property is deleted.
This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c,
s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c.
Rationale for refcount behavior:
* hw/core/qdev.c
- bus children are explicitly unreferenced, don't interfere
- parent_bus is essentially a read-only property that doesn't hold a
refcount, don't unref
- hotplug_handler is leaked, do unref
* hw/dma/xilinx_axidma.c
- rx stream "dma" links are set using set_link, therefore they
need unref
- tx streams are set using set_link, therefore they need unref
* hw/net/xilinx_axienet.c
- same reasoning as hw/dma/xilinx_axidma.c
* hw/pcmcia/pxa2xx.c
- pxa2xx bypasses set_link and therefore does not use refcounts
* hw/s390x/s390-virtio-bus.c
* hw/virtio/virtio-pci.c
* hw/virtio/virtio-rng.c
* ui/console.c
- set_link is used and there is no explicit unref, do unref
