pngstest: make error limits version specific

Browse Source 
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
