This CL removes copy and assign support from Buffer and changes various parameters from Buffer to CopyOnWriteBuffer so they can be passed along and copied without actually copying the underlying data. With this changed some parameters to be "const" and fixed an issue when creating a CopyOnWriteBuffer with empty data.
