RFR: ChaCha20 and ChaCha20/Poly1305 Cipher implementations

Hello everyone,

This is a quick update to the previous webrev:

* When using the form of engineInit that does only takes op, key and 
random, the nonce will always be random even if the random parameter is 
null.  A default instance of SecureRandom will be used to create the 
nonce in this case, instead of all zeroes.

* Unused debug code was removed from the ChaCha20Cipher.java file

* ChaCha20Parameters.engineToString no longer obtains the line separator 
from a System property directly.  It calls System.lineSeparator() 
similar to how other AlgorithmParameter classes in 
com.sun.crypto.provider do it.
