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.
To components. Because tab-completion works better when there aren't two
things starting with bower, and shorter names are nicer to deal with in
general.
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!

Moved all test code into /test. Renamed test.js to crypto_test.js.
(Let's try to keep test files topical.) Merged test_views.html and
test.html into a single test/index.html.
Todo: use Grunt to generate test/index.html from index.html and files
found in /test. Also, write more tests.
We now correctly and opportunistically use the webcrypto API if
available, polyfilling if it's not detected. This change also includes a
layer of abstraction over the webcrypto interface so we no longer have
to deal with key-imports or algorithm names all over the place. Since we
no longer support AES-CTR, code outside this file can simply call
`textsecure.subtle.<encrypt|decrypt|sign>(key, data [, iv])`.
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'.
