support/download: add explicit no-hash support
Add support to explicitly state that an archive has no hash. This can be used for archives downloaded from a repository, like a git-clone or a subversion checkout, or using the github helper. This will come in handy when we'll eventually make hashes mandatory as soon as a .hash file exists: for some packages, like gcc, some versions are downloaded as archives from upstream, while other versions may come from a GitHub repository (via the github herlper). In this case, a .hash file would exist, that contains hashes for the downloaded tarballs, but archives downloaded from the repository would not have a hash (since it is currently not possible to have reproducible such archives). So, we'd need a way to explicitly state there is no hash, on purpose, for those archives. So, add 'none' as a new type of hash. Signed-off-by: "Yann E.
