M18: Use appropriate logging levels
===================================
An appropriate log level should be used depending on the type of message
being logged. Logging is done using the l_log APIs in ELL:
l_error An unexpected condition ocurred. These are generally fatal to the
current connection/protocol that is running but not generally to IWD's
overall operation.
l_warn An unexpected, but non-fatal condition ocurred
l_notice Should not be used directly. This log level is reserved for special
event type notifications which is handled by iwd_notice().
l_info Information that is expected during normal operation. l_info's use
should be very limited so non-debug logs are concise
l_debug General debugging. These can be used relatively freely but should
provide some piece of useful information.
