Subject: [PATCH 01/10] device: rework device's _NMLOG() logging macro
- if the interface-name is NULL, print [null], to distinguish
it from (ifname).
- evaluate the ifname only once.
(cherry picked from commit f10b95880666fe611fb2d0c27d49bfe3988ec9ec)
(cherry picked from commit 60ce882419201f75ac762e559854c85926263fe1)

Subject: [PATCH 04/10] manager: add logging macro _NMLOG2() for logging device
messages
It unifies the way how we print the logging prefix, but also it
passes the ifname down for structured logging.

Subject: [PATCH 05/10] manager: add logging macro _NMLOG3() for logging
connection messages
It unifies the way how we print the logging prefix, but also it
passes the con_uuid down for structured logging.

Subject: [PATCH 08/10] device: remove logging for emitting RECHECK_ASSUME
signal
The device's RECHECK_ASSUME signal has only NMManager as subscriber
and it immediately calls recheck_assume_connection().
With the previous commit, recheck_assume_connection() always logs
a debug message, so we don't need this duplicate message anymore.

Subject: [PATCH 10/10] device: suppress logging and return error reason from
nm_device_generate_connection()
Don't log in a function that basically just inspects state, without
mutating it. Instead, pass the reason why a connection could not be
generated to the caller so that we have one sensible log message.
