This patch contains the following possible cleanups:
- #if 0 the following unused functions:
- zlib_deflate/deflate.c: zlib_deflateSetDictionary
- zlib_deflate/deflate.c: zlib_deflateParams
- zlib_deflate/deflate.c: zlib_deflateCopy
- zlib_inflate/infblock.c: zlib_inflate_set_dictionary
- zlib_inflate/infblock.c: zlib_inflate_blocks_sync_point
- zlib_inflate/inflate_sync.c: zlib_inflateSync
- zlib_inflate/inflate_sync.c: zlib_inflateSyncPoint
- remove the following unneeded EXPORT_SYMBOL's:
- zlib_deflate/deflate_syms.c: zlib_deflateCopy
- zlib_deflate/deflate_syms.c: zlib_deflateParams
- zlib_inflate/inflate_syms.c: zlib_inflateSync
- zlib_inflate/inflate_syms.c: zlib_inflateSyncPoint
