Subject: [PATCH 1/3] core: omit "dev -" for *_to_string of NMPlatformIP*
addresses and routes
The NMPlatformIP[46]Address and NMPlatformIP[46]Route structs have a
field 'dev'. Before this field was always printed in the *_to_string
functions and a missing device was signaled as ' dev -'.
This had the advantage, that the output contained the same fields
regardless whether there was a device set or not.
Change it, not to print the device if it is not set. This has the
advantage, that it looks better in the logfiles.
(cherry picked from commit 69d154012d5f144c97d07f965bad35e1d9306900)
