libinterimap: SSL_fingerprint now supports a space-separate list of digests to pin.
And succeeds if, and only if, the peer certificate SPKI matches one of
the pinned digest values. Specifying multiple digest values can key
useful in key rollover scenarios and/or when the server supports
certificates of different types (for instance RSA+ECDSA).
