Safe JCE Cipher input/output streams and AEAD support for LW Cipher input/output streams

_Some of the new tests here will fail on issues fixed by https://github.com/bcgit/bc-java/pull/31_

Two parts to this:
1.  rewrites of JCE javax.crypto.CipherInputStream and CipherOutputStream that don't silently eat invalid ciphertext exceptions and don't call doFinal() twice (i.e. can be used and used safely with AEAD ciphers). See links below for issues with javax.crypto versions.
2. improvement to LW API CipherInputStream and CipherOutputStream to support AEADBlockCiphers and simplify internal logic.

Full testing of JCE and LW Cipher streams with common ciphers is included, including tampering of AEAD ciphertexts.
