Deflate/inflate was reworked to move common zlib calls into single
functions [rw]util.c. A new shared keyword check routine was also added

possible to call png_inflate() incrementally.
possible to call png_inflate() incrementally. A warning is no longer
issued if the language tag or translated keyword in the iTXt chunk
has zero length.
If benign errors are disabled use maximum window on ancilliary inflate.

chunks could end up with a too-small windowBits value in the deflate
