function fb_api_check_session in Drupal for Facebook 5.2

Same name and namespace in other branches

1. 6.3 fb.module \fb_api_check_session()
2. 6.2 fb.module \fb_api_check_session()
3. 7.3 fb.module \fb_api_check_session()

Sometimes calls to fb_api_init succeed, but calls to the client api will fail because cookies are obsolete or what have you. This function makes a call to facebook to test the session. Expensive, so use only when necessary.
