TypedArray.prototype.set doesn't handle ArrayBuffers correctly (it
writes all zeros). Instead, wrap each ArrayBuffer in a typed array
for concatenation.
processData (default: true)
Type: Boolean
By default, data passed in to the data option as an object (technically,
anything other than a string) will be processed and transformed into a
query string, fitting to the default content-type
"application/x-www-form-urlencoded". If you want to send a DOMDocument,
or other non-processed data, set this option to false.

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.
Sadly, we are not quite compliant with the WC3 webcrypto spec
due to our insistance on passing around key data in plain old
ArrayBuffers.
Also converted whitespace.
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.
An exception is thrown when protobuf tries to encode a number as the
group id, which is declared to have type 'bytes'.
Fix by make it an ArrayBuffer instead, and increase the length to 16,
which is what the Android client uses:
c632b32ff8/src/org/thoughtcrime/securesms/database/GroupDatabase.java (L222)
Previously, if calling createNewGroup with an undefined groupId,
no groupId was generated.
This occurred because no entry for "group" + undefined exists in
localStorage, which caused this code to think undefined was a
valid group id.
Fixed by adding `|| groupId == undefined` to the while clause.
Also decoupled the groupId collision check for clarity.
