The expected usage is efl_text_set(efl_part(layout, part), text);
Same for text_get.
Also, added an example how to make API easier with providing
efl_text_set/get for the widget itself, in efl_ui_button. Please see
this example.
This reverts commit 584e17ae84.
After talking to @herdsman (before xmas) we concluded that we
didn't necessarily want a generic version of efl_text_set/get
for elm_layout. Instead, each widget that should have a default
text part should implement text_set/get themselves (very simple).
Note that Efl.Ui.Text somehow does not "implement" efl_text when
looking at the eolian files. It works by composition.
This implements support for efl_text_set() for the default
part (NULL). This also adds support for efl_text_set(efl_part())
for layouts. This should cover a LOT of widgets :)
The next step is to remove Elm.Layout.text but it's used in too
many places at the moment. @herdsman!!
This touches Edje and also Elementary where part names are used.
This commit blew up in size since now all content part APIs
(get, set, unset) require to use Efl.Part instead.
This is a big refactoring commit, but no logic should
have been changed. Fingers crossed.
