definitions that configure produces, including for WIN64. Still
needs to be tested.
'lld' is not assured by the run-time DLLs and so GCC warns.
Add TIFF_SIZE_T and TIFF_SIZE_FORMAT to provide a type definition
and printf format specifier to deal with printing values of
'size_t' type. In particular, this was necessary for WIN64.
Added a configure test for if the system headers provide 'optarg'
(normal case) and block out the many explicit 'extern' statements
in the utilities. This was found to be necessary under Windows
when getopt is in a DLL and the symbols are already imported with
dllimport via standard header files.

* 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.
