pngstest: make error limits version specific
...
Splitting the machine generated error structs out to a file allows the values to
be updated without changing pngstest.c itself, since libpng 1.6 and 1.7 have
slightly different error limits this simplifies maintenance.

Back-port pngvalid corrections and enhancements
...
This is a patch for libpng16.
It incorporates fixes to the low-bit-depth gray background handling from
libpng17 and turns one of the low-bit-depth gray cases that does work (and,
indeed, did work before) in libpng16

[libpng16] tests backported from libpng 1.7
...
This updates libpng16 with all the test changes from libpng17,
including changes to pngvalid.c to ensure that the original,
distributed, version of contrib/visupng/cexcept.h can be used.
pngvalid contains the correction to the use of SAVE/STORE_
UNKNOWN_CHUNKS; a bug revealed by changes in libpng 1.7. More
tests contain the --strict option to detect warnings and the
pngvalid-standard test has been corrected so that it does not
turn on progresive-read (there is a separate test which does
that.)
Some signed/unsigned fixes have been made.

[libpng16] Fixed array size calculations to avoid warnings. At various points
...
in the code the number of elements in an array is calculated using
sizeof. This generates a compile time constant of type (size_t) which
is then typically assigned to an (unsigned int) or (int). Some versions
of GCC on 64-bit systems warn about the apparent narrowing, even though
the same compiler does apparently generate the correct, in-range,
numeric constant. This adds appropriate, safe, casts to make the
warnings go away.
