cpp/io/basic ios/set rdbuf

Sets the associated stream buffer to without clearing the error state.

This member function is protected: it is called by the move constructors of the derived streams such as std or std, as the final step after constructing the base class and after moving the stream buffer: only the most derived stream class knows how to correctly move the stream buffer, but std needs to be made aware of the stream's new location so that its public member functions can access it.
