1d658302f8 * libtiff/tif_swab.c: if DISABLE_CHECK_TIFFSWABMACROS is defined, do not do 
the #ifdef TIFFSwabXXX checks. Make it easier for GDAL to rename the symbols
of its internal libtiff copy.

6281927e03 * libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(), 
and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
to behave differently depending on whether the codec is enabled or not, and
thus can avoid stack based buffer overflows in a number of TIFF utilities
such as tiffsplit, tiffcmp, thumbnail, etc.
