This was intended to sync the group state of a recently re-installed
client, but is prone to overkill when we have a lot of old stale groups
around. Also this implementation incurs some rate limit errors from the
server.
Uses app-level timestamps for outgoing messages.
Adds timestamp property to the outgoing jsonData.
Triggers a runtime event to notify frontend on delivery receipts.
Renders delivered messages with a 'delivered' class.
ReplayableErrors make it easy for the frontend to handle identity key
errors by wrapping the necessary steps into one convenient little
replay() callback function.
The frontend remains agnostic to what those steps are. It just calls
replay() once the user has acknowledged the key change.
The protocol layer is responsible for registering the callbacks needed
by the IncomingIdentityKeyError and OutgoingIdentityKeyError.

Distills crypto.js down to the hard cryptoey bones. It pulls from
webcrypto for aes and hmac, and from native client for curve25519 stuff
or potentially another object implementing the handful of needed
curve25519 functions.
Everything else formerly known as crypto, including session storage and
management, axolotl, etc.. is now protocol.js. The separation is not
quite perfect, but it's a big step.
nativeclient.js now enables talking to the native client module through
a high level interface as well as registering callbacks that will be
executed once the module is loaded. And it has tests!
Finally, this commit removes all references to the "testing_only"
object, preferring to run tests on textsecure.crypto instead.
Latest protobuf.js requires that we pass in the sign value when making
longs from strings, ex: dcodeIO.Long.fromString(id, true);
However, it does the string->long conversion automatically if its given
a string for a fixed64 field, so we can pass our string ids right in!
ftw
Parse attachment ids out of the attachment pointer url and return them
as strings because the copy parsed by JSON suffers a loss of precision.
Convert them to and from the format expected by the protobuf using
facilities from decodeIO.Long.
DRY up protobuf declarations and move to a slightly briefer naming
convention.
Also dropped some ArrayBuffer -> string conversions as
ProtoBuf.js handles ArrayBuffers just fine, and in fact, more
efficiently than strings.
Finally, dropped the btoa() wrappers, because that incurs an extra
string -> string conversion before the protobuf's internal string ->
array buffer conversion. In lieu of btoa, we can simply pass in the
optional string encoding argument to the protobuf's decode method,
which in these cases should be 'binary'.

All the group messages were being sent to the last recipient in the
list, due to the persistence of `var number` in later loops and async
calls. An easy mistake to make, when you use for instead of each.
