Patch by Hyowon Kim <hw1008.kim@samsung.com> on 2014-03-20
Reviewed by Gyuyoung Kim.

EflUniquePtr is a template alias of std::unique_ptr
with a custom deleter for each Efl Objects, which is motivated by GUniquePtr.
This patch replaces uses of OwnPtr and PassOwnPtr for Efl objects with EflUniquePtr.
