network.subr: Cleanups and minor improvements

* Localize variables in all functions.
* Better name several variables (e.g., $i -> $_if).
* Simplify several test and case usages.
* Use the newly added "-n" option for ifconfig(8) in ifexists().
* Improve comments, debug messages, and styles.
* Print a message when calling rtsol(8) to auto configure an interface,
  since it may take several seconds.
