355d0be78a Introduce new simultaneous initiate strategy.
1) Fix bugs that prevented decrypt() from being non-transactional
   in some cases.

2) Introduce a new unified storage interface.

3) Transition simultaneous initiate from the "needs refresh"
   strategy to one that uses session state resurrection and
   promotion.

741171c49f Switch to CBC mode with a derived IV.
1) Since we're not CPU or space constrained (and are in fact
   padding), and since keystream reuse would be more catastrophic
   than IV reuse without chosen plaintext.

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.

811479d168 Add first cut of protocol v3 support.
1) Use the new /v2/keys API for storing/retrieving prekey bundles.

2) For sessions built with PreKeyBundle and PreKeyWhisperMessage,
   use a v3 ratcheting session when available.

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.

926d3c929f Handle simultaneous initiate protocol case.
1) Modify SessionRecord to store a list of "previous" sessions
   in addition to the current active session.  Previous sessions
   can be used for receiving messages, but not for sending
   messages.

2) When a possible "simultaneous initiate" is detected, push the
   current session onto the "previous session" stack instead of
   clearing it and starting over.

3) Additionally, mark the new session created on a received
   possible "simultaneous initiate" as stale for sending.  The
   next outgoing message would trigger a full prekey refresh.

4) Work to do: outgoing messages on the SMS transport should
   probably not use the existing session if it's marked stale
   for sending.  These messages need to fail and notify the user,
   similar to how we'll handle SMS fallback to push users before
   a prekey session is created.

19dddd7adf Support for an 'end session' protocol message.
1) On the push side, this message is a flag in PushMessageContent.
   Any secure message with that flag will terminate the current
   sessin.

2) On the SMS side, there is an "end session" wire type and
   the convention that a message with this wire type must be
   secure and contain the string "TERMINATE."
