#345
## Description of change
Most games will fail show a network error if there is no network adapter
with a valid IPv4 address
Detect this case in netfix code and show a warning message in log +
deferred error message.
## Testing
Tested with no network adapters, with IPv6 only adapter, and a
disconnected NIC.
## Link to GitHub Issue, if one exists
n/a
## Description of change
Mark the option as "sensitive" which censors the option value (adapter's
IP address)
Remove the log entry from spice
This isn't perfect because most of the games like to log the IP address
and subnet anyway, but at least spice itself will stop doing it.
## Testing
Tested 64 bit LDJ with parameter set.
