8571580aae cmd/ctrld: fatal if failed to get default iface name
So it left a chance for system service manager to bring up ctrld for us.
Without default iface name, ctrld could not work properly anyway.

318fec27de cmd/ctrld: fatal loudly if listen failed
For address already in use error when listening, we have a workaround to
spawn a new listener on different port. However, if that case does not
match, we must fatal to notice the error to user.

eb0dd6235e cmd/ctrld: use NetworkManager to disable DNS manager
Currently, ctrld force NetworkManager ignore auto DNS setup from DHCP
per connection. This does not work well, because an interface can be
attached to many connections. So if `ctrld` started with a connection,
then user connect to new one, the DNS configured by ctrld will be
override.

Instead, we can force NetworkManager not to manage DNS by:

 - Using dns=none
 - Set systemd-resolved=false

So NetworkManager won't attempt to send DNS setup to systemd-resolved,
leaving what ctrld set as-is.

61156453b2 cmd/ctrld: workaround setting DNS issue on Linux
On some Ubuntu systems, we experiment with DNS is not set even though
systemd-resolved log indicates that it set them. To ensure the DNS will
be set, after setting them, double check the current DNS for interface
is actually the value was set, if not, attempting to set again.

While at it, also make sure the DNS is set when ctrld start on Linux.

c82a0e2562 cmd/ctrld: optimizing set/reset DNS
Currently, when reset DNS, ctrld always find the net.Interface by
interface name. This may produce unexpected error because the interface
table may be cleared at the time ctrld is being stopped.

Instead, we can get the net interface only once, and use that interface
for restoring the DNS before shutting down.

While at it, also making logging message clearer.

837563dcd5 all: wait for network up before running
If ctrld setup the interface correctly, the interface DNS is set to
ctrld listener address. At boot time, the ctrld is not up yet, so it
would break the processing Control D config fetching.

Fixing this by waiting for network up before doing the query.
