Fixed new Coverity defect, another NULL dereference of "ps" in pngwutil.c Fixed new Coverity defect, another NULL dereference of "ps" in pngwutil.c
Prevent the CMINFO optimization code from running twice on any PNG IDAT
stream longer than 2048 bytes; the second time could overwrite bytes
2048,2049, invalidating the output.
Fixed a (debug) checks that was slightly wrong (< when <= should have been
used) and this caused write to abort maybe 1 out of 2048 times.
Improved the contrib/examples/pngcp search mode. This is still a
work-in-progress, but it seems fairly stable (if not exactly 100%
optimal). pngcp now allows 'all' for some options which iterates
through all possible settings (this reliably produces the smallest
IDAT that libpng can produce with those settings.) It also contains
a "--search" command line option that attempts to optimize this by
skipping pointless tests; it is close, most of the time, but not perfect.
