Add eXIf support to push mode
...
libpng already supports eXIf as of v1.6.31.
However, it seems like support was added for normal mode and not added
to push mode.
Notice PNG_READ_eXIfJSUPPORTED is in pngread.c:
https://github.com/pnggroup/libpng/blob/libpng16/pngread.c#L178
but is missing from pngpread.c:
https://github.com/pnggroup/libpng/blob/libpng16/pngpread.c#L274
This commit adds eXIf support to push mode.

Replace the remaining uses of PNG_CONST with const
...
In v1.6.0, compiler support for const became a requirement.
It should be used consistently. To maintain backwards compatibility,
PNG_CONST is still maintained in deprecated form.

Fix inconsistent handling of invalid zlib data
...
In libpng 1.6 zlib initialization was changed to use the window size in the zlib
stream, not a fixed value. This causes some invalid images, ones where CINFO is
too large, to display 'correctly' if the rest of the data is valid. This
provides a work-round for zlib versions where the error arises (ones that
support the API change to use the window size in the stream).
