This is only for EO obviously. style_set and theme_set should only be
called when the object is being created, not after. On-the-fly style
changes are complex to handle and in most cases it should be easy to
simply repopulate the object after creating a new one with a new style.
There are only a few cases where style_set is used long after creation
of an object, like changing how a label slides, or in the evas 3d map
examples. Menu seems to change the hover style a lot, so rewriting it in
pure EO would need some extra work, maybe.

This removes an argument that was false only for a single widget:
naviframe. Hopefully this logic is now simpler, even though it involves
a small hack within naviframe itself.

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.
