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.

   use a v3 ratcheting session when available.

   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.

81ee9e31c5 Update behavior for incoming SMS path. 
1) On KitKat, unencrypted SMS messages are never stored in
   TextSecure unless it is set as the system-wide default.

2) On KitKat, if TextSecure is set as the system-wide default,
   provide an option to change the default to a different app.

3) Don't store the TextSecure challenge on KitKat+ devices.

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."

3999171377 Introduce registration-time ID for detecting stale sessions. 
1) At registration time, a client generates a random ID and
   transmits to the the server.

2) The server provides that registration ID to any client
   that requests a prekey.

3) Clients include that registration ID in any
   PreKeyWhisperMessage.

4) Clients include that registration ID in their sendMessage
   API call to the server.

5) The server verifies that the registration ID included in
   an API call is the same as the current registration ID
   for the destination device.  Otherwise, it notifies the
   sender that their session is stale.

0ace469d74 Support for multi-device. 
1) In addition to the Recipient interface, there is now
   RecipientDevice.  A Recipient can have multiple corresponding
   RecipientDevices.  All addressing is done to a Recipient, but
   crypto sessions and transport delivery are done to
   RecipientDevice.

2) The Push transport handles the discovery and session setup
   of additional Recipient devices.

3) Some internal rejiggering of Groups.
