Summary:
We currently call ChildActor.send__delete() when clearing an active transaction
and thereby destroy the child actor. If that happens, e.g. due to a tab switch,
while a message is in the IPC buffer waiting to be delivered, we crash.
This patch creates the child actor lazily as before, but keeps it around until
the WebAuthnManager goes away, which will be at process shutdown.
Each transaction now has a unique id, that the parent process will include in
any of the ConfirmRegister, ConfirmSign, or Abort messages. That way we can
easily ignore stale messages that were in the buffer while we started a new
transaction or cancelled the current one.

Summary:
With both managers storing transaction infos in `Maybe<Info> mTransaction` now,
it occurred to me that we can't actually assert that
`mTransaction.isSome() == true` when we receive a message.
At least with the U2F API the request could be cancelled (and mTransaction
cleared) while there's a pending completion message. For WebAuthn it probably
doesn't hurt to handle this properly either.
(As a bonus, I snuck in the removal of an unused enum.)

Summary:
This patch aims to clean up the WebAuthnManager's state machine, especially
to make cancellation of transactions clearer. To fix bug 1403818, we'll have to
later introduce a unique id that is forwarded to the U2FTokenManager.
There are multiple stages of cancellation/cleanup after a transaction was
started. All of the places where we previously called Cancel() or
MaybeClearTransaction() are listed below:
[stage 1] ClearTransaction
This is the most basic stage, we only clean up what information we have about
the current transaction. This means that the request was completed successfully.
It is used at the end of FinishMakeCredential() and FinishGetAssertion().
[stage 2] RejectTransaction
The second stage will reject the transaction promise we returned to the caller.
Then it will call ClearTransaction, i.e. stage 1. It is used when one of the
two Finish*() functions aborts before completion, or when the parent process
sends a RequestAborted message.
[stage 2b] MaybeRejectTransaction
This is the same as stage 2, but will only run if there's an active transaction.
It is used by ~WebAuthnManager() to reject and clean up when we the manager
goes away.
[stage 3] CancelTransaction
The third stage sends a "Cancel" message to the parent process before rejecting
the transaction promise (stage 2) and cleaning up (stage 1). It's used by
HandleEvent(), i.e. the document becomes inactive.
[stage 3b] MaybeCancelTransaction
This is the same as stage 3, but will only run if there's an active transaction.
it is used at the top of MakeCredential() and GetAssertion() so that any
active transaction is cancelled before we handle a new request.

Bug #: 1409357

The WD-06 (and later) WebAuthn specs choose to move to integer algorithm
identifiers for the signatures [1], with a handful of algorithms identified [2].
U2F devices only support ES256 (e.g., COSE ID "-7"), so that's all that is
implemented here.
Note that the spec also now requires that we accept empty lists of parameters,
and in that case, the RP says they aren't picky, so this changes what happens
when the parameter list is empty (but still aborts when the list is non-empty
but doesn't have anything we can use) [3].
There's a follow-on to move parameter-validation logic into the U2FTokenManager
in Bug 1409220.

There's an intermittent which might be spurious because ASN.1 signatures might
sometimes be less than 70 bytes, but the actual floor is probably 68 (32 + 32
+ 4).
It's a sanity check, so I've adjusted it down and also am now emitting the
offending key bytes if this triggers again.

The Web Authentication types, by spec, return ArrayBuffer objects, while we
were returning a concrete Uint8Array. This is a fairly straightforward change
to add functionality to CryptoBuffer and the WebIDL types, however it's a
substantial change to the tests.
Frankly, the tests just could use another pass of clean-up now, since this is
a lot of relative ugliness added in. I refactored tab_webauthn_success.html
pretty heavily -- since it was also fairly ugly to start -- but I decided to go
with a lighter touch on the other tests.

This should be an easy solution. We can't stop the sign() or register()
runloop from calling the callback, so we need the callback to simply return
early when the U2FHIDTokenManager shuts down.

I wasn't sure whether we want it under the Mozilla org on GitHub, so I pushed
it to ttaubert/rust-runloop for a start. Moving the repository to mozilla/*

One cannot use #[cfg(target_os)] checks in build.rs.
Build scripts can be used to generate code so the target
is set to the host platform when they are compiled.
Having this setting exported an unconditional link
depencency whenever the host was macOS, which broke
cross-compiling, in particular for fennec builds
targetting Android.
Instead, declare the IOKit dependency on the `extern`
block which imports the symbol inside macOS-specific
code. That way final link still works, but the extra
dependency is only enabled when appropriate for the
final target, like the other platform-dependent code.
Summary: We're currently using the thread_rng to derive a cmd byte for the U2F protocol fuzzers. That of course should rather be derived deterministically from the input handed to the fuzzing target.

Now that there are actual hardware devices, this test can't be run: it
depended on there being a deliberately-erroring implementation of WebAuthn
which would instantly reject promises. Fortunately, this test was really more
a test that telemetry scalars work properly than really the functionality
of WebAuthn.
Sadly, I don't see any way to re-enable this test without adding a new test-
only pref to the tree, which doesn't seem worth it for the telemetry.
So this patch removes the offending test completely which was backed out in
https://hg.mozilla.org/integration/mozilla-inbound/rev/c115eec567a6 .

- This patch reworks the U2F module to asynchronously call U2FManager,
which in turn handles constructing and managing the U2FTokenManager
via IPC.
- Add U2FTransaction{Parent,Child} implementations to mirror similar ones for
WebAuthn
- Rewrite all tests to compensate for U2F executing asynchronously now.
- Used async tasks, used the manifest parameters for scheme, and generally
made these cleaner.
- The mochitest "pref =" functionality from Bug 1328830 doesn't support Android
yet, causing breakage on Android. Rework the tests to go back to the old way
of using iframes to test U2F.
NOTE TO REVIEWERS:
Since this is huge, I recommend the following:
keeler - please review U2F.cpp/h, the tests, and the security-prefs.js. Most
of the U2F logic is still in U2F.cpp like before, but there's been
some reworking of how it is called.
ttaubert - please review U2FManager, the Transaction classes, build changes,
and the changes to nsGlobalWindow. All of these should be very
similar to the WebAuthn code it's patterned off.

WD-05 changed the "hashAlg" parameter of the CollectedClientData definition
from using an internally-defined "S256" string to identify the sha256 digest
to the definition in WebCrypto [1]. This only appears once, hard-coded in

WebAuthn operations that are in-flight with authenticators must be cancelled
when switching tabs.
There's an Issue [1] opened with the WebAuthn spec for this already, but the
language is _not_ in spec. Still, it's necessary for security, spec or not.
This also matches how Chromium handles U2F operations during a tab switch.

This patch intends to obtain a 1) rough sense of the percentage of telemetry
population using Web Authentication over time, and 2) whether or not the
Authentication request was successful or errored out as a scalar. It also tracks
3) how long it takes for requests to complete as a histogram.
It counts Register (enrollment) and Sign (login) separately as we would
anticipate there being far, far more Sign uses than Register.
