Split configuration into a separate file.
This saves space and CPU. The configuration can't change (by design) in
a log file, so it was previously being duplicated. In some cases with
lots of forwarded messages and nodes, rotating was triggering
recompression of enough configuration information that we were falling
behind.
Note: on purpose, we aren't storing a link from the log file to the
header. We don't store links between parts either. It up to the user
to provide the config in the list of files and folders provided.
