InflateInputStreambuf is an input stream filter, that inflates the input from the attached input stream.
Deflation/Inflation is a compression/decompression method used in gzip and zip. The zlib library is used to perform the actual inflation, this class only wraps the functionality in an input stream filter.

InflateInputStreambuf constructor.
inbuf | the streambuf to use for input. |
s_pos | a position to reset the inbuf to before reading. Specify -1 to read from the current position. |
del_inbuf | if true is specified inbuf will be deleted, when the InflateInputStreambuf is destructed. |
