Log Message:
Update to 4.0.4

Changelog:
2015-06-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff 4.0.4 released.

	* configure.ac: Add a HAVE_FOO Automake conditional for each
	add-on library.

	* test/Makefile.am (JPEG_DEPENDENT_CHECK_PROG): raw_decode
	requires JPEG support to compile.  Use Automake conditional to
	only include it when JPEG support is available.

	* html/build.html: Try to improve the nmake-based VC++ build
	description.

	* libtiff/tiffconf.vc.h: Build fixes based on testing.

	* libtiff/tif_config.vc.h: Build fixes based on testing.

	* libtiff/libtiff.def: TIFFRasterScanline does not exist so remove
	export for it.

2015-06-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tif_config.vc.h: Make adjustments to match the new
	definitions that configure produces, including for WIN64.  Still
	needs to be tested.

	* configure.ac: For 64-bit MinGW, fix SSIZE_FORMAT formatting
	specifier.  64-bit MinGW supports 'long long' but support for
	'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.

	* test/raw_decode.c (XMD_H): Avoid conflicting typedefs for INT32
	and boolean in MinGW build due to including jpeglib.h.

	* test/rewrite_tag.c (main): Fix problem with location of variable
	declaration.

	* libtiff/libtiff.def: Added exports for TIFFGetConfiguredCODECs,
	TIFFReadRGBAImageOriented, TIFFSetCompressionScheme,
	TIFFSwabArrayOfTriples, TIFFVGetFieldDefaulted, _TIFFCheckRealloc,
	TIFFRasterScanline, TIFFSetErrorHandlerExt,
	TIFFSetWarningHandlerExt, TIFFNumberOfDirectories,
	TIFFCreateCustomDirectory, TIFFCreateEXIFDirectory,
	TIFFWriteCustomDirectory, _TIFFRewriteField as recommended by
	Roger Leigh and justified by use in libtiff tests, documentation,
	and changelog notes.  Also sorted symbol list and removed
	duplicate entries.
