58d101ff2e Support for job "group ids."
A job can specify a group id, and jobs with the same group id
will run sequentially.

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.

3) Reorganize verification tag.

4) Remove verification tag from key exchange messages, replace
   with signatures in both directions.

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.
