Add easy access to MessageDigests in DigestHashFunction

Move the message-digest cloning to DigestHashFunction and out of Fingerprint, to make it possible to configure Fingerprint to use different hash functions. We keep the default MD5 for now, we'd like it to use the global default but want to isolate the configuration change from any change adding potential contention.

RELNOTES: None.
