Constructs new file stream.
1-2) Associates the stream with a file after the constriction. Calls clear() on success or setstate(failbit) on failure.
The first version effectively calls rdbuf()->open(filename, mode).
The second version effectively calls open(filename.c_str(), mode).
3) Move constructor. Constructs the file stream with the state of other using move semantics.
