[RFC,0/5] Using l_notice for low level IWD state information

Message

Lots is explained in the commit description but being able to run
tooling over IWD logs would be very useful to gather statistics on
how IWD is behaving with respect to connections, roaming, or whatever
else is desired. With these patches I've written a tool that monitors
only the NOTICE log level in the journal and spits out much more
concise information about IWD, for example running it against one of
the FT autotests:

James Prestwood (5):
  main: add runtime flag for setting the logger
  station: use l_notice for station_debug_event, allow arguments
  station: add additional station_debug_event's
  netdev: add notice events for connection timeouts
  doc: document use of l_log APIs
