Add support to automatic proxy events from Elementary to Edje using
callbacks described with Evas_Smart_Cb_Description and set to
Evas_Smart_Class or per-instance with
evas_object_smart_callbacks_descriptions_set().
Right now elm_widget is not subclassable, so there is no way to define
class signals, just instance signals.
Just doing it for button, lots of widgets to do... If you can help,
please follow the process:
* see example at src/lib/elm_button.c, copy it.
* read your widget documentation at Elementary.h
* grep for evas_object_smart_callback_call(), see if they are all
documented in Elementary.h, or if there are some missing. Fix Elementary.h
* paste and change based on fixed Elementary.h My recommendation is
to create "static const char []" variables and replace all
evas_object_smart_callback_call() with that, to force sync.
With callback descriptions pre-defined and using the same pointer with
a custom variation evas_object_smart_callback_call_ptr() we may later
optimize signal calling heavily, removing the requirement to call
eina_stringshare_add()/eina_stringshare_del() and also not mixing all
the callbacks in teh same list, instead having an array for defined
signals, and a list from there. These optimizations are not in, but
they are easily added later without breaking the API/ABI.

Now it is possible to change labels and lots of other parameters
directly through Edje's API.
BIG FAT NOTE: this is a convenience that comes with a reasonable
price. If you have hot paths, like loops, then avoid calling this
and use the object directly. This functions add a cost to check
edje, then find the part, then get the type, then get the
param_set/param_get methods, then calling it, then finding the
parameters using strcmp(), then checking the type and just then it
will call the actual method. So whenever possible, just call the
method directly.
Due the reasoning of the "big fat note" I'm adding this inside edje
externals only. The code would be almost the same to expose it in
Elementary.h as elm_widget_property_set/get, but then I know people
would misuse it... actually this kind of stuff could be easily ported
to Evas smart object, but then abuse and slowness will hunt us
foreveeeeer...
