[libpng15] Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left the sBIT fields in the test pixel as 0, which resulted in a floating point division by zero which was irrelevant but causes systems where FP exceptions cause a crash. Added code to pngvalid to turn on FP exceptions if the appropriate glibc support is there to ensure this is tested in the future.
