Thomas Martitz cae4ae2c71 Second try: Introduce plugin_crt0.c that every plugin links.
It handles exit() properly, calling the handler also when the plugin returns
normally (also make exit() more standard compliant while at it).
It also holds PLUGIN_HEADER, so that it doesn't need to be in each plugin anymore.

To work better together with callbacks passed to rb->default_event_handler_ex() introduce exit_on_usb() which will call the exit handler before showing the usb screen and exit() after it.
In most cases rb->default_event_handler_ex() was passed a callback which was manually called at all other return points. This can now be done via atexit().

In future plugin_crt0.c could also handle clearing bss, initializing iram and more.

about the text viewer plugin.

Limitation
    for the target which PLUGIN_BUFFER_SIZE < 0x13000 (i.e., archos series),
    can only be read up to 999 pages.


Difference between viewer.rock
    [settings file]
       - the global setting, 'tv_global.dat' is stored.
       - Settings and bookmarks for each file, 'tv_file.dat' is stored.

      Note: when viewer.dat(viewer_file.dat) exists, tv_global.dat(tv_file.dat) is created by
            using viewer.dat(viewer_file.dat).

    [wod wrap]
          - add the following characters which can be split the line.
                '!', ',', '.', ':', ';', '?', 
                U+00b7, U+2010, U+3000, U+3001, U+3002, U+30fb, U+30fc, 
                U+ff01, U+ff0c, U+ff0d, U+ff0e, U+ff1a, U+ff1b, U+ff1f.

          - when the line split, if the line length is short ( < 0.75 * display width), 
            split the line in display width. (thus, maybe split a word)

    [line mode]
       [join]
           - break line condition has changed.
               - If the next line is a blank line or spaces only line, this line breaks.

       [reflow]
           - indent changes is two spaces (changable in the settings).
           - supports the player which does not define HAVE_LCD_BITMAP.

    [alignment]
           - the right alignment supports the player which does not define HAVE_LCD_BITMAP.

    [bookmark]
           - increased to 16 the number of bookmarks that can be registered.


TODO list
  - for the target which PLUGIN_BUFFER_SIZE < 0x13000 (i.e., archos series),   
    supports more than 999 pages of text.

  - add History feature.

  - draw images that are linked to the text. (<img src="...">)

  - play audios that are linked to the text. (<audio src="...">)

  - more treatments of line breaking, word wrappings.
    (for example, period does not appear the top of line.)
