[PATCH 01/15] service: Add 'service_log_pac' function.

Logs the network service interface name and type at the info level
when the proxy auto-configuration (PAC) URL is set or cleared.

Frequently, a spurious, misconfigured, or otherwise incorrect PAC URL
is the source of connectivity problems, particularly for online
reachability checks.
