819982af7b Rearrange decrypt API.
1) Change SessionBuilder to only establish sessions via
   KeyExchangeMessage and PreKeyBundles.

2) Change SessionCipher to decrypt either WhisperMessage
   or PreKeyWhisperMessage items, automatically building
   a session for the latter.

3) Change SessionCipher to tear down new sessions built
   with PreKeyWhisperMessages if the embedded WhsiperMessage
   fails to decrypt.

72af8b11c2 Move session construction and KeyExchangeMessage into libaxolotl.
1) Add plain two-way key exchange support libaxolotl by moving
   all the KeyExchangeMessage code there.

2) Move the bulk of KeyExchangeProcessor code to libaxolotl
   for setting up sessions based on retrieved prekeys, received
   prekeybundles, or exchanged key exchange messages.

d902c12941 Break core ratchet out into libaxolotol.
1) Break the core cryptography functions out into libaxolotol.

2) The objective for this code is a Java library that isn't
   dependent on any Android functions.  However, while the
   code has been separated from any Android functionality,
   it is still an 'android library project' because of the
   JNI.
