This is VERY tricky.
For legacy, just create an internal class that has both. It's easier
this way. For parts that are handled by Layout directly, we know from
Edje which type to return.
For EO objects we should know from the part name which kind of part we
are dealing with:
- text (overridden by the widget)
- content (overridden by the widget)
- special (new efl_part based functions)
- generic (handled by Layout)
Note: Efl.Ui.Slider was handling "span size" on ALL parts. That's bad...
This is now limited to "span" only.
This means that ALL part handles inherit from the base part class
Efl.Ui.Widget.Part. Layout is the only exception where Efl.Part is
specially overridden.
This is a first step towards generic part APIs, including background in
all widgets.
For this patch I decided to add a pseudo legacy wrapper as the function
is called in a very large number of places. Fixing all those calls to
use the size2d form is a lot of work and a greater risk of b0rking
something.
In Edje and Elementary, we have part objects, which are what is returned
by the interface efl_part(). Those objects can't be of an opaque type as
this doesn't work nicely with strongly typed languages such as C++ or
C#. In JS, Lua, C the types are weak and mostly runtime-based so it
doesn't matter much.
As a consequence, the documentation and the types need to look nice in
this EO API. Thus, we remove the abusive term "internal" and explicitly
call all those classes "part" something.
Eventually we want the types to be declared in the EO file so bindings
(C#, C++, ...) can generate the proper access methods, returning the
best possible types.
Note that right now a few of those part types are used in the legacy API
but don't actually need to be exposed externally.
This is kind of a mega commit that does all the renaming at once, but
it's really just a big sed operation. The power of good IDEs :)

It's not beta. It's about to die.
Also, move #define ELM_WIDGET_BETA to the common header file, as it is
consequently required by ALL widgets. :(

This name makes more sense and one api does the job of two.
We never needed two apis at first place though.
Mark left/right_size_set as legacy apis too.
This patch also implements min_split_ratio on parts.

This allows user to set size hints to be respected and
request panes to ignore combined min size.
If this flag is set, the minimum size set by efl_gfx_size_hint_min_set()
is respected forcefully.

Some names have not been changed, hopefully making a distinction
between legacy APIs and internal code (elm_layout_blah) and valid EO
usages.
This means many internal functions are still elm_layout_ as their
sole purpose is to support the legacy API.
Ref T5315
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.
