This is a duplicate of what's done in be-secure-openssl.c, and it does
not strike me as a good idea to do that potentially twice.
git diff --check complains.

I think that the split done in this patch makes the HMAC handling in
the core code messier:
- SCRAM makes use of HMAC internally, and we should try to use the
HMAC of OpenSSL if building with it even for SCRAM.
- For the first reason, I think that we should also have a fallback
implementation.
- This API layer should not depend directly on the SHA2 used (SCRAM
uses SHA256 with HMAC).
FWIW, I got plans to work on that once I am done with the business
around MD5 and OpenSSL.
The refactoring done with the ciphers moved from pgcrypto to
src/common/ should be a separate patch. In short, it would be good to
rework this patch and split it into pieces that are independently
useful. This would make the review much easier as well.
