Constructs a newshared_future.

1) Default constructor. Constructs an empty shared future, that doesn't refer to a shared state, that isvalid()==false.

2) Constructs a shared future that refers to the same shared state, if any, asother.

3,4) Transfers the shared state held byother to*this. After the construction,other.valid()==false, andthis->valid() returns the same value asother.valid() would have returned before the construction.
