[E-devel] Changing Elementary Python bindings to use ctypedef from the C headers

[Kai H. <kai...@gm...>]

I have attached here a patch which changes the py-elm declarations to
use extern from C header and ctypedef for the C types, instead of
importing and using them from evas. This adds a small amount of code
duplication but simplifies using the C types. Any objections to this?
