This supports more test cases and a reduced licence keyword (now licensing).
The extra text cases require more slack in pngstest.c

This patch adds code to 'makepng' to allow the generation of smaller images that
also give better test case coverage. It also adds copyright and licence to the
generated images, reflecting the fact that they are original works of the author
of the code. The licence used is the Creative Commons Public Domain one,
appropriate to a non-source-code work.
The resultant image were used to generate the updated pngstest-errors.h file in
a prior commit.

Splitting the machine generated error structs out to a file allows the values to
be updated without changing pngstest.c itself, sine libpng 1.6 and 1.7 have
slightly different error limits this simplifies maintenance.
makepngs.sh has also been updated to more accurately reflect current problems in
libpng 1.7
