(element-type) should have a full name like Clutter.Actor rather than
a non-namespaced name like Actor. gobject-introspection has become
more strict about this with the recent scanner rewrite.

The marshallers we use for the signals are declared in a private header,
and it stands to reason that they should also be hidden in the shared
object by using the common '_' prefix. We are also using some direct
g_cclosure_marshal_* symbol from GLib, instead of consistently use the
clutter_marshal_* symbol.
clutter_container_create_child_meta() uses CLUTTER_IS_ACTOR on the
container parameter instead of the actor parameter.

Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.
Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.
As a side note: this commit closes the oldes bug in Clutter's bug
report tool.

It is conceivable that Container implementations might add children
outside of the Container::add() implementation - e.g. for packing at
a specific index. Since the addition (and removal) might happen outside
the common path we need to expose all the API that is implicitly called
by ClutterContainer when adding and removing a child - namely the
ChildMeta creation and destruction.
GLib 2.24 (but starting from the 2.23.2 unstable release) added a new
macro for collecting GValues from a va_list.
The newly added G_VALUE_COLLECT_INIT() macro should be used in place
of initializing the GValue and calling G_VALUE_COLLECT(), and improves
the collection performances by avoiding multiple checks, free and
initialization calls.
In the default implementation of container::destroy_child_meta Set child
meta qdata to NULL on the child and not the container, since the child
is the object that owns the data.
Since an actor can only be parented to one container we don't need
the extra complications of maintaining a list of ChildMeta objects
attached to an actor in the default implementation of the Container
interface.
Bug 1517 - clutter_container_foreach_with_internals()
This allows us to iterate over all children (for things like maintaining
map/realize invariants) or only children that apps added and care about.

Add annotations such as (transfer-none) (out) (element-type ClutterActor),
and so forth to the doc comments as appropriate.
The annotations added here are a combination of the annotations previously
in gir-repository for Clutter and annotations found in a review of all
return values with that were being parsed with a transfer of "full".

* clutter/clutter-container.[ch]: Add checks to the Container
interface invocation methods, to avoid crashing or corrupting
the stack when an actor does not implement every virtual
function of the Container interface vtable. GObject allows this
to happen so we must handle the case gracefully. This also means
that we can classify some virtual function as mandatory (as is
the case for ::add, ::remove and ::foreach) and some other
optional.
* clutter/clutter-child-meta.c:
(clutter_child_meta_set_property),
(clutter_child_meta_class_init): Make the :container and
:actor properties of ChildMeta construct-only, to allow
bindings to actually use ChildMeta without abusing the API.
* clutter/clutter-container.c (create_child_meta): Instead of
setting the members of the ChildMeta structure, use the
constructor properties.
Bug 882 - Allow child properties for containers implementing the
ClutterContainer interface (Øyvind Kolås)
* clutter/clutter-child-meta.[ch]: Base class for the metadata
of a ClutterActor inside a ClutterContainer; the ChildMeta
object implements a wrapper for storing data that is attached
to a ClutterActor only when it's part of a ClutterContainer.
The ChildMeta object is used to store the child properties
accessible through the ClutterContainer API.
* clutter/clutter-container.[ch]: Creates the ChildMeta for
each actor, in case the Container specifies the ChildMeta
type to use.
* clutter/Makefile.am: Add clutter-child-meta.[ch] to the build.
* clutter/clutter-marshal.list: Add the marshaller for the
ClutterContainer::child-notify signal.
* clutter/clutter-types.h: Declare ClutterContainer and
ClutterChildMeta to avoid recursive inclusion.
* clutter/clutter-container.c:
(clutter_container_get_type): Relax the precondition on the
implementations of ClutterContainer from ClutterActor to
GObject.
from interface (and all implementations of it) since this
functionality is now implemented using a global hash.
* clutter/clutter-box.c:
* clutter/clutter-group.c:
Language bindings will have problems with raise() and lower() bein in both
ClutterContainer and ClutterActor; hence, this patch renames
clutter_container_raise() and clutter_container_lower() to
clutter_container_raise_child() and clutter_container_lower_child(),
respectively.
Since ClutterActor directly calls ClutterGroup methods we need ClutterContainer
to provide them, so that every container actor behaves the same way.
This patch makes ::raise, ::lower and ::sort_depth_order virtual functions
of the ClutterContainer interface, implemented by ClutterGroup.
The documentation has been added and deprecation warnings have been added
as well.
Finding a child by its ID is a method that should be used by every container
and not only by ClutterGroup. This is needed to actually fix the picking in
ClutterStage.
