This was supposed to solve the problem of losing group state after a reinstall
by inspecting member registration ids and pre-emptively sending group updates to
those who appear newly re-registered, but it has been unused since 6123c419.
Nowadays there's a protocol for requesting lost group state from other members.
// FREEBIE
Previously, updateNumbers would throw an Error, so the whole group
update was discarded.
Signal-Android handles this the same way in
GroupMessageProcessor.handleGroupUpdate().
Closes#1056
Now that we simply establish and save a session via SessionBuilder
rather than saving the keys to pass in during encrypt, we can stop
caching them in memory in between the identity key check and the
encryption step.
// FREEBIE
Fix a bad loop scope bug in getKeysForNumber by using forEach.
Refactor the initial process of establishing key material for devices
that do not have open sessions.

This one's been around since forever, but only manifests when someone
leaves the group and comes back. In that case we fail to reinit their
numberRegistrationId object, which causes a npe when we try to send
send them group messages.
Affected parties must ask their fickle friends to leave/join again.

* Session records are now opaque strings, so treat them that way:
- no more cross checking identity key and session records
- Move hasOpenSession to axolotl wrapper
- Remote registration ids must be fetched async'ly via protocol wrapper
* Implement async AxolotlStore using textsecure.storage
* Add some db stores and move prekeys and signed keys to indexeddb
* Add storage tests
* Rename identityKey storage key from libaxolotl25519KeyidentityKey to
simply identityKey, since it's no longer hardcoded in libaxolotl
* Rework registration and key-generation, keeping logic in libtextsecure
and rendering in options.js.
* Remove key_worker since workers are handled at the libaxolotl level
now
