WIP partial writes
...
If possible, downloads are streamed to disk in the /pending/ directory
in the tar filesystem. If the download is successful and the checksums
match the file is renamed to its sha256 hash. Otherwise, it is moved
under /to-delete/ so it can be deleted by an operator.
Before downloading we check if it has been downloaded before, but we
need to check as well if it is being downloaded (in /pending/) or if we
unsuccessfully downloaded it before (e.g. failed checksum, stored in
/to-delete/).
It is not very elegant code, and it could do with a thorough review or
rewrite.
