TYPE_IOMMU_MEMORY_REGION is a direct subtype of TYPE_MEMORY_REGION.
Its instance struct is IOMMUMemoryRegion, and its first member is a
MemoryRegion. Correct. Its class struct is IOMMUMemoryRegionClass,
and its first member is a DeviceClass. Wrong. Messed up when commit
1221a47467 introduced the QOM type. It even included hw/qdev-core.h
just for that.
TYPE_MEMORY_REGION doesn't bother to define a class struct. This is
fine, it simply defaults to its super-type TYPE_OBJECT's class struct
ObjectClass. Changing IOMMUMemoryRegionClass's first member's type to
ObjectClass would be a minimal fix, if a bit brittle: if
TYPE_MEMORY_REGION ever acquired own class struct, we'd have to update
IOMMUMemoryRegionClass to use it.
Fix it the clean and robust way instead: give TYPE_MEMORY_REGION its
own class struct MemoryRegionClass now, and use it for
IOMMUMemoryRegionClass's first member.
Revert the include of hw/qdev-core.h, and fix the few files that have
come to rely on it.

pcnet_receive already checks the conditions and drop packets if false.
Due to the new semantics since 6e99c63 ("net/socket: Drop
net_socket_can_send"), having .can_receive returning 0 requires us to
explicitly flush the queued packets when the conditions are becoming
true, but queuing the packets when guest driver is not ready doesn't
make much sense.

All NICs have a cleanup function that, in most cases, zeroes the pointer
to the NICState. In some cases, it frees data belonging to the NIC.
However, this function is never called except when exiting from QEMU.
It is not necessary to NULL pointers and free data here; the right place
to do that would be in the device's unrealize function, after calling
qemu_del_nic. Zeroing the NIC multiple times is also wrong for multiqueue
devices.
This cleanup function gets in the way of making the NetClientStates for
the NIC hold an object_ref reference to the object, so get rid of it.

Add a qom property with the same name 'bootindex',
when we remove it form qdev property, things will
continue to work just fine, and we can use qom features
which are not supported by qdev property.
