bookmarks: drop deprecated methods (API)

The ProgrammingError prevents accidental usage of the dict base class methods.

.. api::

   The following deprecated methods have been removed from bookmarks:
   __setitem__(), __delitem__(), update(), and recordchange().  Use
   bookmarks.applychanges() instead.
