API renaming

A couple of points:

1.  Quite a while ago, we (the team at the time) made a decision to
    have all new APIs prefixed with 'OPENSSL_' or 'OSSL_'.  It seems
    that we never voted on it, though, but still.

2.  The new RAND API hasn't been merged yet, so it's not like we're
    renaming something that already exists.

So in terms of "it's just a prefix", OSSL_ would be just as suitable.
It's a bit more blatantly "OpenSSL", though.
