Constructs new synchronized output stream
1-4) constructs the private member std::basic_syncbuf using the buffer and the allocator provided, and initializes the base class with a pointer to the member std::basic_streambuf.
5) Move constructor. Move-constructs the std::basic_ostream base and the std::basic_syncbuf member from the corresponding subobjects of 
other, then calls set_rdbuf with the pointer to the newly-constructed underlying std::basic_syncbuf to complete the initialization of the base. After this move constructor, other.get_wrapped() returns nullptr and destruction of other produces no output.Parameters
| buf | - | pointer to the std::basic_streambuf that will be wrapped | 
| os | - | reference to a std::basic_ostream, whose rdbuf() will be wrapped | 
| a | - | the allocator to pass to the constructor of the member std::basic_syncbuf | 
| other | - | another osyncstream to move from |
