Methods get told which hashes are expected by the acquire system, which means we can use this list to restrict what we calculate in the methods as any extra we are calculating is wasted effort as we can't compare it with anything anyway. Adding support for a new hash algorithm is therefore 'free' now and if a algorithm is no longer provided in a repository for a file, we automatically stop calculating it. In practice this results in a speed-up in Debian as we don't have SHA512 here (so far), so we practically stop calculating it.
