Add PQencryptPasswordConn function to libpq, use it in psql and createuser.

Browse Source 
The new function supports creating SCRAM verifiers, in addition to md5
hashes. The algorithm is chosen based on password_encryption, by default.

This fixes the issue reported by Jeff Janes, that there was previously
no way to create a SCRAM verifier with "\password".
