scroller: Introducing Efl.Ui.Scroller

scrollable widgets had a interface_scrollable as a mixin so that the
widgets had a 'is-a' relation with interface_scrollabe. however, new
scroller concept don't have 'is-a' relationship, but 'has-a'
relationship. scrollable widgets should have a scroll manager inside
them, then scroll manager handles event from user and api
implementations. and also we cut the features such as paging because
there will be aka 'elm_pager'.

we are expecting that the new concept make us to maintain the scroller
easier. please excuse for many unorganized code and logics. : (

Note by @jpeg:
Unfortunately this patch comes in a massive single blob, after too many
rebase operations. It has now come to a point where I think the API is
nice and it works as I'd expect.
Now I only wonder how applicable this will be for Efl.Ui.List. As we can
see Photocam (legacy and unified API) could be transformed to use this
new API.
