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.

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.
