Summary:
historically there have been two methods of calculating sizes in elm:
* elm_layout_sizing_eval
* evas_object_smart_calculate (now efl_canvas_group_calculate)
the former was used to set size hints on widgets, while the latter was
used to perform internal size calcs for the widget. for things to
work correctly, these functions had to be triggered in just the right
order at just the right time. many hard-to-fix bugs related to widget
sizing over the years have been the result of this split
this patch removes elm_layout_sizing_eval implementations so that all
widgets perform both internal size calcs and size hint setting all
in the same function, ensuring that these are always in sync
the result is that in the vast majority of cases, far fewer recalcs
happen for widgets, and they are quicker to achieve their final size

this takes the current generated output from eolian for legacy code in
efl and adds it to the tree, then removes legacy references from the
corresponding eo files. in the case where the entire eo file was for
a legacy object, that eo file has been removed from the tree

It is my understanding that some items view are created with efl_add directly
and manipulate VIEW directly with Eo new API. This clash with the inconsistent
behavior that evas_object_del expect. To work around this, we track object life
by explictely relying on efl_wref_add while holding the pointer to the object.
This changes a lot of things all across the EFL. Previously,
methods tagged @const had both their external prototype and
internal impl generated with const on object, while property
getters only had const on the external API. This is now changed
and it all has const everywhere.
Ref T6859.
This thing is used by only 2 EO APIs that are marked as @beta. I wonder
if the @beta tag or the ptr() expression made it work for eolian,
because it simply wasn't defined in EO.
I'm renaming it just so that it's more consistent with the new names
used by atspi (and EO API in general).
This will be used to solve issues around style_set:
if the widget is legacy or pure eo we may need to select a different
style. So in the constructor we need to know whether we are legacy or
eo. Note that calling style_set in finalize only is too late as we would
lose information such as efl_text_set() called inside efl_add().
This factorizes the code and makes most widgets handle key down events
in the same way:
- check that the object is not disabled, event is not on hold
- figure out the key binding based on the class name
- mark event as on hold
The class name is usually MY_CLASS_NAME but in some cases it was
MY_CLASS_NAME_LEGACY which may be different from the EO class name (eg.
elm_win vs. Efl.Ui.Win). In that case the key bindings are broken.
This breaks key bindings for the following widgets:
- Win (focus)
- Image ("clicked")
- Video (move, play)
This fixes key bindings for the following widgets:
- Nstate
Some widgets remain broken:
- Photocam / Efl.Ui.Image.Zoomable
A patch will be applied to restore the key bindings for the above
breaks.
This is an internal function that should probably become an overridable
protected method, as it's required for proper event handling in widgets.
Next step: use eo_event_info in the widgets implementations. Then remove
legacy event struct.
Ref T5363
elm_layout_sizing_eval() marks an object as requiring recalc.
Unfortunately, it's been massively abused by various widgets into
actually doing the calc, or the min calc. So we end up with one API
that has 3 different definitions depending on the widget type:
1. Mark as requiring recalc (correct, respects doc, elm_layout)
2. Calculate min size and other size hints
3. Actually do some geometry modification
I believe we need to clarify these 3 requirements into 3 very clear
and specific APIs in elementary. Right now we have similar functions
in evas for 1 (evas_object_smart_changed) and 3 (smart_calculate).
But their exact definition also isn't necessarily what we want for
elementary.
Another clear problem is that layout_eval does not do any calculation
(in theory), so the "eval" word is a bit of a stretch here.
Once we're sure about the exact API we want, we can add this back to
EO and make it work across our EO widgets. For now let's just keep
the legacy API, and its EO overrides, as is.

Summary:
Elm.Widget.event_callback_add conflicts with Efl.Object.event_callback_add.
To solve this problem, "widget_" prefix is added to methods starting with
"event".

This fixes compilation for terminology for example.
Thanks to @Etrunko for the report.
Note: My builds originally worked fine because my installed
include folder contained the old files :(
Efl.Object.event_callback_call no longer calls legacy smart callbacks;
calling only event callbacks registered with the given event description
pointer.
Create the method Efl.Object.event_callback_legacy_call to inherit the old
behavior from Efl.Object.event_callback_call, calling both Efl.Object events
and legacy smart callbacks.
Update all other files accordingly in order to still supply legacy
callbacks while they are necessary.
This reverts commit 546ff7bbba.
It seems that eo_del() is useful and removing it was creating bugs.
The issue is that the way we defined parents in eo, both the parent and
the programmer share a reference to the object. When we eo_unref() that
reference as the programmer, eo has no way to know it's this specific
reference we are freeing, and not a general one, so in some
circumstances, for example:
eo_ref(child);
eo_unref(child); // trying to delete here
eo_unref(container); // container is deleted here
eo_unref(child); // child already has 0 refs before this point.
We would have an issue with references and objects being freed too soon
and in general, issue with the references.
Having eo_del() solves that, because this one explicitly unparents if
there is a parent, meaning the reference ownership is explicitly taken
by the programmer.
eo_del() is essentially a convenience function around "check if has
parent, and if so unparent, otherwise, unref". Which should be used when
you want to delete an object although it has a parent, and is equivalent
to eo_unref() when it doesn't have one.
We used to have eo_del() as the mirrored action to eo_add(). No longer,
now you just always eo_unref() to delete an object. This change makes it
so the reference of the parent is shared with the reference the
programmer has. So eo_parent_set(obj, NULL) can free an object, and so
does eo_unref() (even if there is a parent).
This means Eo no longer complains if you have a parent during deletion.
