DEBUG: Allow debug_fn to process __FILE__ and __LINE__

In preparation for enabling journald support for the DEBUG logs, we
will need to be able to pass in certain additional arguments that will
be required, specifically the code file and line number.

We will be able to optionally enable this in the file-based logs as well
if we so choose, but for right now we will avoid breaking the log
format on disk.
