JENA-1812: Switch to Murmur3 for blank node allocation
> Migrate blank node hash algorithm from MD5 to SHA-256

> MD5 is a deprecated hashing algorithm, and even though it is not used on
> sensitive data in the context of Jena, its usage is picked up by security
> softwares as a security flaw. This may reduce the incentive to use Jena in
> commercial products, and computing SHA-256 hashes is not prohibitively more
> expensive than MD5.
>
> Therefore, I suggest to migrate from using MD5 hashes to SHA-256.
