inflate() for file i/o applications, in that it avoids copying between the

output and the sliding window by simply making the window itself the output

buffers. inflateBack() trusts the application to not change the output

inflateBackInit() must be called first to allocate the internal state
|

and to initialize the state with the user-provided window buffer.
