The buffer allocation rework will remove most of the methods in the Stream class. The methods who deals with buffers will be virtual and implemented in a subclass. This change adds the prototypes for the new interface with an empty default implementation. Once the new buffer allocation work is completed the two added prototypes here will be turned into pure virtual functions preventing the base Stream class from being instantiated.
