bouncycastle: add support for PKCS5S2 algorithm parameters

Java 8 allows to specify a PBE key using only the password (as opposed
to password + salt + iteration count) and generate the encryption key
later by specifying the rest of the parameters in an AlgorithmParameters
object.

Adding these AlgorithmParameters in BouncyCastle together with support
in ciphers.
