02f9c2f9c7 Remove unnecessary complexity
Opam 2 only supports md5, sha256 and sha512. We don't need the extra
complexity of other hash algorithms. Opam 2 will fail to parse such an
opam file anyway.

6490801ce1 Update dependencies, refactor
- Tar.3.0.0 was released! So we can drop the pin and depend on it
  directly.
- Use digestif in favor of the bygone mirage-crypto hash
- Move most of the hashing logic into archive_checksum.ml
- When checking the checksum we should check the checksum chosen, too. I
  believe this was a bug that was hidden due to opam packages always
  using one of md5, sha256 or sha512 for checksums.

8e326ecbc5 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.

24dda11659 Hash cache
The block devie is partitioned into a tar rw filesystem and two hash map
cache partitions. The latter store the computes maps from {md5,sha512}
checksums to sha256 checksums to speed up the boot process.
