    Fixes for adding users with friendscontrol set to 'auto' (bug #861985)

    Adding users who automatically accept friends failed when the page
    from which the form was submitted was out of date. This change fixes
    the case where a user adds a friend who has changed their friendscontrol
    setting since the page was loaded. If they have turned friendscontrol
    back to 'auth', the submission will fail with an error; if they have in
    the meantime added a friend request to the user who's submitting the
    form, it will succeed, and if a user with an open friend request somehow
    submits the 'addfriend' form, the friend request will be removed.
