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.
Ref T5301
After reverting 8a21384759, I figured out how to move
the main menu back to the border group. This time the menu is in the
framespace and its layout algos have been adapted to allow non-zero
root coordinates.
