(a filtered version of) the default logger which we implemented in the library but was no longer accessible. This makes it much easier for the caller to turn logging on by just passing this default log handler callback pointer into xmpp_ctx_new() instead of having to always implement boilerplate. Another option would have been xmpp_get_default_log_level(ctx, level) to change the filter level of the build in logger, which is installed if you pass NULL to xmpp_ctx_new(). In this method the logger would filter everything by default.
