Buffer cumulate(BufferAllocator alloc,
                Buffer cumulation,
                Buffer in)

Cumulate the given Buffers and return the Buffer that holds the cumulated bytes. The implementation is responsible to correctly handle the life-cycle of the given Buffers and so call Resource.close() if a Buffer is fully consumed.
