>+        Use std::unique_ptr instead of PassOwnPtr in MediaPlayerFoo classes
>+        https://bugs.webkit.org/show_bug.cgi?id=137765
>+
>+        Reviewed by NOBODY (OOPS!).
>+
>+        As a step to use std::unique_ptr|make_unique<>, this patch changes use of OwnPtr|PassOwnPtr with
>+        std::unique_ptr<>|make_unique<>. However we have to set constructor to public in order to use
>+        std::make_unique<>. This change will conflict with MediaPlayerFoo's create() factory function
>+        because there are two object creation methods. Thus this patch removes create() factory function
>+        in MediaPlayerFoo classes and also lets MediaPlayerFactory create MediaPlayerFoo using std::make_unique<>
>+        instead of the create() factory functions.
>+
>+        No new tests, no behavior changes.
