[libpng16] Removed one of the GCC-7.1.0 'strict-overflow' warnings that
result when integers appear on both sides of a compare. Worked around the others by forcing the strict-overflow setting in the relevant functions to a level where they are not reported. Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like the space. Worked around some C-style casts from (void*) because g++ 5.4.0 objects to them. Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint overflow' check that is on by default with -Wall -Wextra.
