tdf#114939 sfx2: notify user of non-interoperable passwords
For ODF 1.1 encryption, SHA1 is used as the start-key digest algorithm
of PBKDF2.
For the ODF export password-to-modify "feature", PBKDF2 is used
without a start-key digest round, so the UTF-8 encoded password
is directly the input.
In both cases, if the user entered a password with a known problematic
length, reject it and request a new one.
