mod_bookmarks2: Use max_items='max' on trunk, with fallback check_node_config() throws an error attempting to compare the pep_max_items number with the 'max' string, which allows detecting and support using 'max' where available. Unsure what happens when you upgrade, that seems a problem for a future commit! :)

This module discards typing notifications sent to a bare host JID,
preventing error replies to be sent. These errors are harmless but can
be annoying sometimes if your client shows them prominently.
