	Reorganized the way JPEG comments and metadata are loaded.
	
	* plug-ins/jpeg/jpeg-load.c (load_image): sanitize comments
	containing invalid UTF-8 instead of discarding them.  If there is
	more than one EXIF block in a file, merge all of them instead of
	keeping only the block that contains a thumbnail image (see also
	bug #446809 and bug #358117).  Process XMP after EXIF.

	* plug-ins/jpeg/jpeg.h: include two null characters as part of the
	EXIF header.

	* plug-ins/jpeg/jpeg-exif.c: added jpeg_exif_get_orientation(),
	removed jpeg_apply_exif_data_to_image() because this is now done
	directly in jpeg-load.c.

	* plug-ins/jpeg/jpeg-icc.c
	* plug-ins/jpeg/jpeg-icc.h: removed jpeg_icc_setup_read_profile()
