util: move md5 back next to sha1 and allow to call it without an argument

This effectively backs out changeset 908c5906091b.

The API change is done so that both util.sha1 and util.md5 can be called the
same way. The function is moved in order to use it for md5 checksumming for
an upcoming bundle2 feature.
