After ab23a53094, evas_object_size_hint_align_set()

to do so but we don't change the old behaviour.
This patch is an effort to make evas_object_size_hint_align_set()
to work with elm img again.

Thanks to dave for reporting and jpeg to show the right fix.
fixes T4635
Inside efl_part() we don't know whether we are dealing with a text
or content API, so we can't actually guess the proper alias.
The legacy API should have already dealt with aliasing at this point.
The EO API should not use those aliases.
This in theory should only affect the EO API usage. In EO
we don't want efl_part() to be used for NULL part. In other
words, there is no "default" part in EO objects. Instead, those
functions like text_set or content_set should simply be
implemented by the object themselves.
The legacy API on the other hand will make sure that the
"part" argument is set to a non-NULL value before reaching
this point.
This is a follow-up to a4b79fdbe1.
efl_part no longer supports NULL parts.
NULL text parts are now aliased in legacy code beforehand.

Omg this was a pain... The code is complete spaghetti and the
fact that the main menu is now in the framespace doesn't help
either. With this patch and the previous one (about ecore_evas_x)
Edi should be able to open correctly at the proper size and with
a visible menu.
This patch introduces a lot of changes so it'll need testing
before we accept it fully.
Fixes T5482
This should fix issues when the main menu is wider than the
window content. This assumes that the menu is horizontal and
aligned with the client content.
The theme should probably handle this case better but right
now I am lost in the spaghetti resizes happening between
edje, elm, evas and X...
I am not very happy with this patch, and I think border.edc
needs some love in order to make it more robust and simpler
to read.

This affects the legacy content_set/get/unset part APIs. This
should avoid some unwanted ERR messages in case an elm_object_
API is used on an elm widget that doesn't implement said API.
What this does is request the widget for the name of the default
part if NULL was passed in. Since some widgets are not elm_layout,
they have to override the API themselves, which is why I made it
an internal EO API (rather than a series of efl_isa()).
In theory, part should never be NULL when reaching the internal
implementation code in the widgets, at least for content.
In EO, efl_part(obj, NULL) should be invalid.

Also, "Efl.Text.Format" is shortened to now include the "_format"

"Efl.Text.Font" keeps the "_font" prefix, for better readability.
This should later be setup through the theme.
One option will be to use global text classes.
Until the above is finalized, at least set this font and size to make
setup of the widget a bit easier.
The following API is now supported with efl_part:
- Efl.Text.text { set; get; }
- Efl.Text.Cursor.cursor { get; }
- Efl.Text.Cursor.cursor_paragraph_first;
- Efl.Text.Cursor.cursor_paragraph_last;

- Efl.Text.Cursor.cursor_copy;
- Efl.Text.Cursor.cursor_content { get; }
- Efl.Text.Cursor.cursor_geometry { get; }
- Efl.Text.Cursor.cursor_text_insert;
Many of the 'part_text' functionality was moved to legacy, too.
See the edje_object.eo to see which ones are still supported.
Originally it was its own object.
There are some valid claims that there is no justification for it to
remain an object.
Furthermore, it's apparent that it added little benefit: changes of
each cursors, in practice, triggered a query for all objects of the
same textblock. There wasn't real advantage to have a finer resolution
of controlling the cursors with their own events.
This ports back a lot of code, and changes a lot of other code in the
higher-up widgets, such as Efl.Ui.Text and co.
The usage was replaces from:
efl_canvas_text_cursor_char_next(cur_obj)
to
efl_canvas_text_cursor_char_next(text_obj, cur_obj)
that is, it is an operations on the TEXT OBJECT, rather than on the
(now removed) cursor object.
So, one less efl object to worry about now.
Hopefully, the port went smooth.

Eina Debug is a layer aimed to bring a way to debug EFL applications by
providing a transport channel between a debug tool and the applications
of a device.
In order to be interrupted by EFL core as less as possible, the communication
is done in a separated thread.
The Ecore loop is not used there, as well as the Ecore helpers (socket...).
Debugging operations can be registered easily by any layer of the application.
To use it:
- Launch efl_debugd
- Launch the application to debug
- Launch Clouseau (the new version will be pushed soon) or another debug tool
supporting Eina Debug
The expected usage is efl_text_set(efl_part(layout, part), text);
Same for text_get.

This removes Evas.Modifier_Mask from EO.
This introduces two new types instead:
- Efl.Input.Modifier
- Efl.Input.Lock
Those are enums, not strings, containing all the known and

bit masks.
This effectively removes the ability for an application to
create and handle specific modifier or lock keys - with EO
API (legacy compatibility is unchanged, of course). I wonder
who ever required this?
This may be a bit more controversial...
But Evas_Coord really is just an int and all the internals
