Otherwise, it just looks odd:
"not priority 31265 from 0.0.0.0/0 fwmark 0xcb87 table 52103"
Better is:
"priority 31265 not from 0.0.0.0/0 fwmark 0xcb87 table 52103"
The "not" specifier should come after the priority. It makes more sense
to read it that way. As far as parsing the string is concerned, the
order does not matter. So this change in behavior is no problem.

We should prefer the cleanup macors nm_auto*() because they express
ownership in code.
Also, they allow to return early without additional cleanup code.
That way we can refactor if-else blocks.
Also, in cases where we intentionally pass on the reference, we use
g_steal_pointer(), which literally spells out what happens in code.
If we find a matching connection, ensure it's exactly as we want it
before actually proceeding to activate it. Fixes this problem:
# nmcli dev wifi connect "Network of Doom" password santa <-- bad
Error: Connection activation failed: (7) Invalid secrets
# nmcli dev wifi connect "Network of Doom" password satan <-- correct
Error: Connection activation failed: (7) Invalid secrets
The password is now correct, but nmcli chose to re-activate the wrong
connection it created previously.
Do not check for password when creating a simple connection object for
"nmcli dev wifi connect".
This makes no difference in practice. The password is checked for
existence later on and the connection instance is created anyway. This
just makes things look a bit more consistent.
They should be "static" and only visible to this source file.
Also, they should be "const", that allows the linker to place them
into read-only memory.

For better or worse, the API does not require the value to be a
UTF-8 string. We cannot just concatenate binary to a string.
Instead, backslash escape it with utf8safe-escape.
Also, this will shut up a (wrong) coverity warning at this place.
(cherry picked from commit 55143dad95)
I was aware that this code is not reachable. But for consistency, it
seems better to be explict about it (to avoid future bugs when refactoring).
Anyway, Coverity complains about it. So assert instead.

priv->start_buttons and priv->end_buttons are initialized at
construction and never changed and so the checks are not needed.

These are special -- initramfs configured them and killed dhclient. Bad
things would happen if we let the addresses expire though.
Let's act as if initramfs actually passed the configuration to us.
It actually tries to do so by the means of writing an ifcfg file, but
that one is too broken to be useful, so the ifcfg-rh plugin ignores it.
Notably, it doesn't have the actual addresses or correct BOOTPROTO.
The generated connection is better.

When we build n-dhcp4 for NetworkManager we get a compiler warning.
This can also be reproduced by building n-dhcp4 alone:
