        * exif.c: Use new format_raw_exif_offset() function to find Exif in
        raw files.
        * filelist.c: Add orf and pef to displayed file types.
        * format_canon.h, format_fuji.h: Update to new #define format.
        * format_fuji.c: Use same offset for Exif as the jpeg image as the
        Exif is always embedded in the jpeg and assuming offset of 12 is
        just broken.
        * format_nikon.h: Update to new #define format, and add pentax here
        as finding the jpeg will be same code.
        * format_olympus.[ch]: Support Olympus raw files with embedded jpegs,
        not all raw files will have a jpeg, but all appear to have Exif tags.
        * format_raw.[ch]: Add new camera types, and add a debugging facility
        to easily list all tags within tiff files (see format_raw.h to enable).
