This enables checking if an object is being created, or has already been
finalized. This is useful in functions that you want to allow
only during the creation phase (i.e inside the eo_add()).
This function lets you hook at the end of eo_add and override it for a
class. This is essentially the first step towards killing custom
constructors. Instead of having a custom constructor, you should just
do:
eo_add(CLASS, parent, a_set(3), b_set("eou"));
eo_constructor is called at the beginning for pre-init things.
eo_finalize is called at the end, for actually finalizing and doing
things. This cleans up the API and possibly saves a lot of things that
would have been stupid and slow in the past, like loading an elm widget
with an existing theme, and then changing the theme.
** This breaks Eo ABI, please recompile elementary and everything else that
creates eo objects.
