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.
