For god-knows-what reason, at-spi is trying various formats
of strings when registering listeners, triggering an ugly
(gnome-shell:4411): Clutter-WARNING **: invalid object type create
warning in .xsession-errors. Stop doing that.
Also don't leak temporary string arrays that are a side-effect
of passing parameters around as formatted strings.

A bunch of private functions we use when parsing got exposed accidentaly
to the list of public symbols by virtue of not having the leading '_'
that we use to filter them out of the shared object — all the while the
header that declares them is a private, non installed one.
Let's rectify this situation with a bit of minor surgery on the code.
The priv->text field cannot ever be NULL, so we don't need to check for
that in a series of places. We also need to assert() that pre-condition
in the couple of places where we set the contents of the ClutterText
actor, namely in set_text_internal() and set_markup_internal().
Based on a patch by: Dan Winship <danw@gnome.org>

Setting :use-markup and :text is currently not idempotent, and it
depends on the ordering, e.g.:
g_object_set (actor, "use-markup", TRUE, "text", value, NULL);
does not yield the same results as:
g_object_set (actor, "text", value, "use-markup", TRUE, NULL);
This is particularly jarring when using ClutterText from ClutterScript,
but in general GObject properties should not rely on the order when used
from g_object_set().
The fix is to store the contents of the ClutterText as a separate string
from the displayed text, and use the contents, instead of the displayed
text, when toggling the :use-markup property.
Let's also add a unit test for good measure, to try and catch
regressions.

There is no prebuilt package for ATK 2.1.5 which Clutter now depends
on so let's build it from source instead. The ATK packages don't have
a .gz version so this patch also changes it to download the .bz2
version of json-glib to avoid having to accept both formats.
The easing test is a nice example of what ClutterAnimation and
clutter_actor_animate() can do. The "tween ball to the pointer
event coordinates" is a bit of a staple in animation libraries
and their documentation.
