Implement buffer lazy initialization before writeBuffer This patch implements buffer lazy initialization before writeBuffer(): if the buffer is not initialized and writeBuffer() doesn't cover the whole buffer, the buffer will be cleared to 0, otherwise the buffer shouldn't be cleared. This patch also introduces a toggle LazyClearBufferOnFirstUse for the development of buffer lazy initialization: before buffer lazy initialization being completely supported, all the related code will only be enabled behind this toggle to prevent the buffers with valid content being unexpectedly cleared.
