There is no reason for every user to have to write the same code

Thanks. I'll merge this change. I think we don't need to declare prototypes in spdylay_gzip.h because they are declared in spdylay.h. Also I will change the signatures of the functions to match the convention of the existing code:

• z_stream spdylay_new_inflate_stream() -> int spdylay_gzip_inflate_stream_init(z_stream )
  • The new function expects z_stream is allocated by the caller.
• void spdylay_free_inflate_stream(z_stream* stream) -> void spdylay_gzip_inflate_stream_free(z_stream *)
  • The new function expects z_stream is deallocated by the caller after the call.
• int spdylay_inflate_data(...) -> int spdylay_gzip_inflate_stream(...)

I realized that current API does not expose zlib to the application. I want to keep this property. To achieve this, z_stream would be encapsulated in spdylay_gzip struct and its implementation is hidden from the application. The API will be:

• int spdylay_gzip_inflate_new(spdylay_gzip **)
• void spdylay_gzip_inflate_free(spdylay_gzip *)
• int spdylay_gzip_inflate(spdylay_gzip *, ...)
