function fb_exit in Drupal for Facebook 6.3

Same name and namespace in other branches

1. 5.2 fb.module \fb_exit()
2. 5 fb.module \fb_exit()
3. 6.2 fb.module \fb_exit()
4. 7.3 fb.module \fb_exit()

Implements hook_exit().

When completing a canvas page we need special processing for the session. See fb_session.inc.

Also invoke hook_fb(FB_OP_EXIT), so that other modules can handle special cases (in particular form support in fb_canvas.module.

TODO: remove this hook, for compatibility with Drupal's aggressive caching. Modules that currently look for FB_OP_EXIT will need to implement hook_exit on their own.
