Subject: src/config.c: Add junk callback to config_file_walk()
This can be used if we care about junk, such as empty lines and
comments. Currently unused since we skip these when parsing
configuration settings. This makes sense if we want to make slight
modifications to the configuration file without losing formatting and
comments, though.
