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

This prevents legacy EO classes from being exposed through .eo.h headers
or .eo in share/eolian/includes. Also removes a slew of useless xxx_eo.h
intermediate headers.
Notes:
- elm_systray has no proper API: it's not clear if the EO API should be
released (in which case it needs to be renamed to efl_something) and
there is no legacy API to create a systray object.
- Some files have been placed in a "FIXME" section, as I believe they
are necessary within EO land, but at the same time still don't
conform to the interfaces (eg. name starts with elm_).
- elm_interface_scrollable is required by photocam. This means photocam
needs to be adapted to fit the EO scroller API (still to be
completed, I believe).
Bugs:
- This breaks most C++ examples. I KNOW. And I'm working on it.

This makes sure that
elementary_test -to "Window Plug"
exits nicely (with the exit policy on all window close) instead of
hanging forever with an invisible window.
@fix
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.
