[PATCH 6/7] station: use iwd_notice for state/event information

[James Prestwood <prestwoj@gmail.com>]

For anyone debugging or trying to identify network infrastructure
problems the IWD DBus API isn't all that useful and ultimately
requires going through debug logs to figure out exactly what
happened. Having a concise set of debug logs containing only
relavent information would be very useful. In addition, having
some kind of syntax for these logs to be parsed by tooling could
automate these tasks.

This is being done, starting with station, by using iwd_notice
which internally uses l_notice. The use of the notice log level
(5) in IWD will be strictly for the type of messages described
above.
