This commit changes hmp_cont() to loop through all block devices
and proactively set an encryption key for any encrypted device
missing a key.

This change is needed because QERR_DEVICE_ENCRYPTED is going to be
dropped by a future commit.

In the old QMP days, this code was used to find out QMP commands that
might be calling monitor_printf() down its call chain.

This is almost impossible to happen today, because the qapi converted

a year since I used this last time.

The current implementation of Interfaces is poorly designed.  Each interface
that an object implements ends up being an object that's tracked by the
implementing object.  There's all sorts of gymnastics to deal with casting
between these objects.

But an interface shouldn't be associated with an Object.  Interfaces are global
to a class.  This patch moves all Interface knowledge to ObjectClass eliminating
the relationship between Object and Interfaces.

Interfaces are now abstract (as they should be) but this is okay.  Interfaces
essentially act as additional parents for the classes and are treated as such.

With this new implementation, we should fully support derived interfaces
including reimplementing an inherited interface.

PC: Rebased against qom-next merge Jun-2012.

PC: Removed replication of cast logic for interfaces, i.e. there is only
one cast function - object_dynamic_cast() (and object_dynamic_cast_assert())

Re-implemented the interconnect between the Xilinx AXI ethernet and DMA
controllers. A QOM interface "stream" is created, for the two stream interfaces.

As per Edgars request, this is designed to be more generic than AXI-stream,
so in the future we may see more clients of this interface beyond AXI stream.

This is based primarily on Paolos original refactoring of the interconnect.

For each newly created RAM block, dirty bitmap is reallocated with g_realloc, which doesn't
make any promises on initial content of new extra data in returned buffer. In theory,
we initialize this new data with cpu_physical_memory_set_dirty_range() call. The
problem is, cpu_physical_memory_set_dirty_range() has a side effect of incrementing
ram_list.dirty_pages variable, but only for pages which are not already dirty. And
page "cleanliness" is determined using the same not yet uninitialized dirty bitmap
we've just reallocated. This results in inconsistency between real dirty page number
and value in ram_list.dirty_pages variable, which in turn could (and will) result
in errors during VM migration.
Zero initialize new dirty bitmap bytes to fix this problem.
