f7d5419816 [libpng16] Avoid filter-selection heuristic sum calculations in cases where 
only one filter is a candidate for selection. This trades off code size (added

cfc19ff1b6 pngcp bug fixes 
The fixed size buffer for the file name being processed could have a byte
written beyond the end; a bug where the test was updated without changing the
size of the buffer.  This commit reduces the buffer to the system maximum.

png_getrowbytes could, in theory, return 0; probably only if there is a bug in
libpng but the code now checks.

54feb0ad2a pngimage: correct #define checking 
In libpng 1.7 pngimage needs to check PNG_WRITE_PNG_SUPPORTED (new in 1.7), not
PNG_WRITE_SUPPORTED because png_write_png can be disabled without disabling
PNG_WRITE_SUPPORTED.  Copied the approach from 1.6 pngcp.c (so this still works
in 1.6 as well.)

9957c45073 pngcp: add high resolution timing 
If PNG_PNGCP_TIMING_SUPPORTED is defined maximal resolution CPU time logging of
png_read_png and png_write_png is enabled via the --time command line option.
This is not on by default but is enabled by contrib/conftests/pngcp.dfa

0ac91cc657 pngcp: tool to copy PNG files 
This adds pngcp to the build together with a pngcp.dfa configuration test; the
test revealed some configuration bugs which are fixed by corrections to the
_SUPPORTED macros.

pngcp builds on all tested configurations and a number of bugs have been fixed
to make this happen relative to the version in libpng 1.7 contrib/examples.
pngcp.dfa will have to be different for 1.7 but pngcp.c should work fine (not
yet tested).  pngcp itself is still missing a usage message; this is a
preliminary version, although since it behaves the same way as 'cp' most unoids
shouldn't have a problem using it correctly.
