새로운 shared_future 를 생성합니다.

1) 기본 생성자. 빈 shared future를 생성하며, 공유 상태를 참조하지 않습니다. 즉 valid ( ) == false 입니다.
2) 동일한 공유 상태(있는 경우)를 참조하는 shared future를 생성합니다. 이는 other 와 동일한 상태를 참조합니다.
3,4) other 가 보유한 공유 상태를 * this 로 이전합니다. 생성 후에는 other. valid ( ) == false 이며, this - > valid ( ) 는 생성 전 other. valid ( ) 가 반환했던 값과 동일한 값을 반환합니다.
