Please note that on a related thread that I have begun yesterday,
Heikki has suggested some changes in the way we handle the opaque data
used by each cryptohash implementation.
https://www.postgresql.org/message-id/6ebe7f1f-bf37-2688-2ac1-a081d278367c@iki.fi

As the design used on this thread for HMAC is similar to what I did
for cryptohashes, it would be good to conclude first on the interface
there, and then come back here so as a consistent design is used.  As
a whole, I don't think that there is any need to rush for this stuff.
I would rather wait more and make sure that we agree on an interface
people are happy enough with.
