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()).
as stated in f92e5d50, instead of using eo_add_custom() thus a custom
constructor and maybe overriding the default constructor to block it,
- use the default constructor to build the object
- add calls to eo_add(), to initialize the object
eo_add(class, parent, val_a_set(1), val_b_set(2), ... );
- override eo_finalize to validate the object and if needed,
use eo_error_set(obj) to abort object construction
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.

Summary:
2 threads run 'eo2_do(o, a(), b());'
- A goes first, creates an object, enters 'eo2_do(o, a(), b());'
in a() call, it blocks, releases B and waits for it.
- B when released, creates an object, enters 'eo2_do(o, a(), b());'
in a() call, it joins and releases A, then blocks.
- A returns from a(); and enters b() using current call stack frame,
which is the one pushed by B! then pop the frame and releases B.
- B does as above using the stack pushed by A!
as we don't support multiple composites of the same class,
and know at class elaboration how many composites we should have,
we can create the composites array and pack it at the end of the object.
eo_composite_attach fail if the class of the composite is not
listed in the parent class extensions, or if there is already a
composite of the same class. The later because calls are
forwarded to the first responding composite, see _eo_op_internal().
This reverts commit 1714fe93f4.
We actually want this type, it makes things clearer.

We want to introduce a new mechanism concerning the data of the Eo
objects.
The goal is to improve the memory management by defragmenting the memory
banks used by the Eo objects. The first phase has been done by raster
and consists in allocating the objects into a separate memory region
that the one used by malloc. So now, we know where our objects are
located.
Now, moving objects means moving data of objects. The issue we have here
is that a lot of data pointers are stored into data of other objects,
e.g Evas Object data into lists for rendering...
We need a way to reference the data and eo_data_get doesn't provide us
that. So we need to improve the API for data extraction by requesting
from the developer if the data will be stored or not. Five functions are
supplied:
- eo_data_scope_get: no referencing, the data pointer is no more used after
exiting the function.
- eo_data_ref: reference the data of the object. It means that while the
data is referenced, the object cannot be moved.
- eo_data_xref: reference the data of the object but for debug purpose,
we associate the objects that references. Same behavior as eo_data_ref
for non-debug.
- eo_data_unref: unreference the data of an object.
- eo_data_xunref: unreference the data of an object previously
referenced by another object.
I deprecated the eo_data_get function. Most of the time,
eo_data_scope_get needs to be used.
In the next patches, I changed the eo_data_get to the corresponding
functions, according to the usage of the data pointer.
The next step is to find all the places in the code where the data is
stored but not yet referenced. This will be done by:
- requesting from every object to unreference all data to other objects.
- moving all the objects from one region to another
- requesting from every object to rerefenrence the data.
- debugging by hunting the segmentation faults and other weird
creatures.
These functions let you pass an array of callbacks instead of just one.
It's more memory efficient to use this if you just add a bulk of events
on the same object.
This commits breaks ABI, and breaks API of the EO_EV_CALLBACK_ADD/DEL
signals (the event info passed).
We now need to pass the current class to eo_do_super. This is faster and
more memory efficient and generally lets us do things better.
Using the eo_benchmarks we get ~20% speed-up.
This was stupid from the start, but now it casuse even more issues.
We'll have to just add a configure option to it when the time comes.

It doesn't affect proto/eobj so no need to do it there too.
There are things we only test if NDEBUG is not passed to Eo. Eo itself was
compiled with NDEBUG but the tests were not notified about it so those tests
failed.
Many thanks to Vincent and Stefan for bugging me about it non-stop, without
you guys, I may never have gotten to it.
