Daniel Gasienica b6ef67c402 Sync Protocol Buffers with `libsignal-service-java` (#2046)
Synchronizes our protocol buffers with `libsignal-service-java` project.

**Changes**
- [x] **BREAKING:** Rename `package` from `textsecure` to `signalservice`.
      ⚠️~~Workaround: Rename back to `textsecure`.~~
      Changed all protobuf `package` names across our project.
- [x] Rename `java_` metadata.
- [x] Move `NullMessage`, `ReceiptMessage`, and `Verified`.
- [x] Rename `Contacts.isComplete` to `Contacts.complete`. Confirmed to be
      unreferenced in our project.
- [x] Rename `Settings` to `Configuration` (`textsecure.protobuf.Settings` seems
      to be unused)
  - [x] Rename `libtextsecure` `MessageReceiver` `settings` event to
        `configuration`.
- [x] Rename `ReceiptMessage.timestamps` to `ReceiptMessage.timestamp`.
- [x] Add `AttachmentPointer` `width` and `height`.
- [x] Renamed `IncomingPushMessageSignal.proto` to `SignalService.proto` to
      match server.

Profiles (#1453)
* Add AES-GCM encryption for profiles

// FREEBIE

* Decrypt and save profile names

// FREEBIE

* Save incoming profile keys

* Move pad/unpad to crypto module

// FREEBIE

* Support fetching avatars from the cdn

// FREEBIE

* Translate failed authentication errors

When AES-GCM authentication fails, webcrypto returns a very generic error. The
same error is thrown for invalid length inputs, but our earlier checks in
decryptProfile should rule out those failure modes and leave us safe to assume
that we either had bad ciphertext or the wrong key.

// FREEBIE

For standalone accounts, generate a random profile key.

// FREEBIE

* Special case for one-time sync of our profile key

Android will use a contact sync message to sync a profile key from Android
clients who have just upgraded and generated their profile key. Normally we
should receive this data in a provisioning message.

// FREEBIE

* Infer profile sharing from synced data messages

* Populate profile keys on outgoing messages

Requires that `profileSharing` be set on the conversation.

// FREEBIE

* Catch errors on profile save

// FREEBIE

* Save our own synced contact info

Don't return early if we get a contact sync for our own number

Certificate pinning via node XMLHttpRequest implementation (#1394)
* Add certificate pinning on https service requests

Make https requests to the server using node apis instead of browser apis, so we
can specify our own CA list, which contains only our own CA.

This protects us from MITM by a rogue CA.

As a bonus, this let's us drop the use of non-standard ports and just use good
ol' default 443 all the time, at least for http requests.

// FREEBIE

* Make certificateAuthorities an option on requests

Modify node-based xhr implementation based on driverdan/node-XMLHttpRequest,
adding support for setting certificate authorities on each request.

This allows us to pin our master CA for requests to the server and cdn but not
to the s3 attachment server, for instance. Also fix an exception when sending
binary data in a request: it is submitted as an array buffer, and must be
converted to a node Buffer since we are now using a node based request api.

// FREEBIE

* Import node-based xhr implementation

Add a copy of https://github.com/driverdan/node-XMLHttpRequest@86ff70e, and
expose it to the renderer in the preload script.

In later commits this module will be extended to support custom certificate
authorities.

// FREEBIE

* Support "arraybuffer" responseType on requests

When fetching attachments, we want the result as binary data rather than a utf8
string. This lets our node-based XMLHttpRequest honor the responseType property
if it is set on the xhr.

Note that naively using the raw `.buffer` from a node Buffer won't work, since
it is a reuseable backing buffer that is often much larger than the actual
content defined by the Buffer's offset and length.

Instead, we'll prepare a return buffer based on the response's content length
header, and incrementally write chunks of data into it as they arrive.

// FREEBIE

* Switch to self-signed server endpoint

* Log more error info on failed requests

With the node-based xhr, relevant error info are stored in statusText and
responseText when a request fails.

// FREEBIE

* Add node-based websocket w/ support for custom CA

// FREEBIE

* Support handling array buffers instead of blobs

Our node-based websocket calls onmessage with an arraybuffer instead of a blob.
For robustness (on the off chance we switch or update the socket implementation
agian) I've kept the machinery for converting blobs to array buffers.

// FREEBIE

* Destroy all wacky server ports

lilia 9f4fcc5afa Send null messages to mask verified syncs
First construct a null message of random size and contents and send it to the

lilia 07702c4ee5 Let the application layer send sync messages
Previously, libtextsecure would send a sync message automatically
when appropriate. This fails if any recipient has a key conflict
or if our network connection fails mid-send.

Instead, when appropriate, return a the DataMessage encoded as an array
buffer for later syncing. This lets the application choose when to send
it, which we now do after any successful send to a recipient, rather
than after all recipients are successfully sent to.

Eventually we should move the DataMessage protobuf construction and
group sending logic to the application layer entirely, in which case
we wouldn't need libtextsecure to construct the sync message either.
