-Fix potentially uninitialized value.
-
-Depending on what ReadOK does it's possible for |dircount16| to be used without
-being initialized. The read code calls back into PDFium specific code which then
-calls into the stream reading code.
-
-Initialize the value to be sure it is set.

-[libtiff] Validate refblackwhite values
-
-The td_refblackwhite value is currently assigned without validation. This
-may pose an issue as the image can specify the value as nan. This will cause
-problems later when we use the nan in calcluations.
-
-This CL validates each of the float values are not nan and if they are sets
-them to the default provided by the TIFF spec v6.

-Fix leak in PredictorSetupDecode by calling tif_cleanup on failure
-
-tif_data and tif_cleanup are both set on the TIFFInit methods, see for
-instance TIFFInitPixarLog. If PredictorSetupDecode fails, whatever was
-filled on tif_data should be cleaned up. The previous leak fix from
-PixarLogSetupDecode is no longer necessary.

-Libtiff: Prevent OOM in TIFFFillStrip
-
-In TIFFFillStrip, calls to TIFFReadBufferSetup may allocate large amounts of
-memory. In this CL we do sanity checks on the claimed size of the raw strip
-data before that happens, to prevent out-of-memory.
