* libtiff/tif_dir.c: TIFFSetField(): refuse to set negative values for
TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION that cause asserts when writing
the directory
* libtiff/tif_dirread.c: TIFFReadDirectory(): refuse to read ColorMap or
TransferFunction if BitsPerSample has not yet been read, otherwise reading
it later will cause user code to crash if BitsPerSample > 1
* libtiff/tif_getimage.c: TIFFRGBAImageOK(): return FALSE if LOGLUV with
SamplesPerPixel != 3, or if CIELAB with SamplesPerPixel != 3 or BitsPerSample != 8
* libtiff/tif_next.c: in the "run mode", use tilewidth for tiled images
instead of imagewidth to avoid crash
* tools/bmp2tiff.c: fix crash due to int overflow related to input BMP dimensions
* tools/tiff2pdf.c: fix crash due to invalid tile count (should likely be checked by
libtiff too). Detect invalid settings of BitsPerSample/SamplesPerPixel for CIELAB / ITULAB
* tools/tiffcrop.c: fix crash due to invalid TileWidth/TileHeight
* tools/tiffdump.c: fix crash due to overflow of entry count.
sp->dec_codetab in LZWPreDecode (bug #2459)
* libtiff/tif_read.c: in TIFFReadBufferSetup(), avoid passing -1 size
to TIFFmalloc() if passed user buffer size is 0 (bug #2459)
* libtiff/tif_ojpeg.c: make Coverity happier (not a bug, #2459)
* libtiff/tif_dir.c: in _TIFFVGetField() and _TIFFVSetField(), make
Coverity happier (not a bug, #2459)
* libtiff/tif_dirread.c: in TIFFFetchNormalTag(), make Coverity happier
(not a bug, #2459)
* tools/tiff2pdf.c: close PDF file (bug #2479)
* tools/fax2ps.c: check malloc()/realloc() result (bug #2470)
* tools/tiffdump.c: detect cycle in TIFF directory chaining (bug #2463)
and avoid passing a NULL pointer to read() if seek() failed before (bug #2459)
* tools/tiffcrop.c: fix segfault if bad value passed to -Z option
(bug #2459) and add missing va_end in dump_info (#2459)
* tools/gif2tif.c: apply patch for CVE-2013-4243 (#2451)
TIFF_UINT64_FORMAT appropriately for MinGW32.
* tools/tiffdump.c (ReadDirectory): MinGW32 needs to use WIN32
printf conventions for 64-bit types because it uses the WIN32 CRT.
* libtiff/{tif_dumpmode.c,tif_luv.c,tif_lzw.c,tif_print.c,
tif_read.c,tif_strip.c,tif_thunder.c}: MinGW32 needs to use WIN32
printf conventions for 64-bit types because it uses the WIN32 CRT.
* tools/tiff2pdf.c (t2p_write_pdf_string): Fix printf syntax not
understood by WIN32 CRT.
consistent (__int64) casting when testing if _lseeki64 has
successfully seeked as requested. This is necessary for large
file support to work since off_t is only 32-bit.
