Version 1.6.32beta12 [August 11, 2017]

Added a set of "huge_xxxx_chunk.png" files to contrib/testpngs/crashers,
one for each known chunk type, with length = 2GB-1.
Check for 0 return from png_get_rowbytes() in contrib/pngminus/*.c to stop
some Coverity issues (162705, 162706, and 162707).
Check for 0 return from png_get_rowbytes() and added some (size_t) typecasts
in contrib/pngminus/*.c to stop some Coverity issues (162705, 162706,

Renamed chunks in contrib/testpngs/crashers to avoid having files whose
names differ only in case; this causes problems with some platforms
(github issue #172).
