Subject: [PATCH] - CURLOPT_COOKIELIST needs curl 7.15 - fixed  typo in
 phpstr.h - reimplemented encoding api - removed
 http_gzencode()/http_gzdecode(); zlib *can* do that - http_deflate() accepts
 various flags now, pass   HTTP_DEFLATE_TYPE_GZIP for gzip encoding;  
 HTTP_DEFLATE_TYPE_ZLIB (default) for HTTP deflate (AKA zlib) encoding  
 HTTP_DEFLATE_TYPE_RAW for raw deflate encoding (same as PHPs gzdeflate); -
 http_inflate() can decode all 3 formats
