Merge to XFA: Clear decoders after the image decoder in the /Filter array.
During decoding, when an image decoder is encountered, any subsequent decoders are ignored, but remain in the array. However, later on CPDF_DIBSource::ValidateDictParam expects the image decoder to be the last in the array, causing issues. A check is also added in CPDF_DIBSource::GetScanline to ensure that the calculated pitch value is <= the (4-aligned) pitch value in the cached bitmap to prevent future issues. Also cleans up some NULL usages. BUG=552046 TBR=tsepez@chromium.org Review URL: https://codereview.chromium.org/1406943005 . (cherry picked from commit 182d129bcee8f7731b9bbfde0064295ad3b37271) Review URL: https://codereview.chromium.org/1436153003 .
