[PATCH] lib/zlib*: cleanups

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
