Description

write out a list of special dump files per dump run that downloaders may want

[WIP] Needs some refactoring.

A list of special files that aren't the output files from a particular
dump job. These include things like status files, checksum listings, etc.
Downloaders and mirrors may want them. This list will be useful for
rsyncing partly complete runs; we want these files along with any
complete output files.
