In Bug 1448408 ("Don't listen to visibility events"), it became possible to
close a tab without a visibility event to cause transactions to cancel. This
is a longstanding bug that was covered up by the visibility events. This patch
updates the cycle collection code to ensure that transactions get cleared out
safely, and we don't proceed to RejectTransaction (and subsequent code) on
already-cycle-collected objects.

The published recommendation of L1 for WebAuthn changed the visibility/focus
listening behaviors to a SHOULD [1], and Chromium, for reasons like our SoftU2F
bug [0], opted to not interrupt on tabswitch/visibility change.
Let's do the same thing.
This changes the visibility mechanism to set a flag on an ongoing transaction,
and then, upon multiple calls to the FIDO/U2F functions, only aborts if
visibility had changed. Otherwise, subsequent callers return early.
This is harder to explain than it is really to use as a user. I think. At least,
my testing feels natural when I'm working within two windows, both potentially
prompting WebAuthn.
Note: This also affects FIDO U2F API.

Summary:
Always replace attestation statements with a "none" attestation.
Bug 1430150 will introduce a prompt that asks the user for permission whenever
the RP requests "direct" attestation. Only if the user opts in we will forward
the attestation statement with the token's certificate and signature.

Late-breaking rename pre-CR in Web Authentication [1] renamed a dictionary. It's
not an interop issue, really, which must be why it was let through. This is a
WebIDL and Web Platform Tests-only issue. (The WPT updates are happening at

Bug #: 1396907
Differential Revision: https://phabricator.services.mozilla.com/D323
Summary:
We currently have a single WebAuthnManager instance per process that's shared
between all CredentialContainers. That way the nsPIDOMWindowInner parent has
to be tracked by the transaction, as multiple containers could kick off
requests simultaneously.
This patch lets us we have one WebAuthnManager instance per each
CredentialsContainer and thus each nsPIDOMWindowInner. This matches the current
U2F implementation where there is one instance per parent window too.
This somewhat simplifies the communication diagram (at least in my head), as
each U2F/WebAuthnManager instance also has their own TransactionChild/Parent
pair for IPC protocol communication. The manager and child/parent pair are
destroyed when the window is.

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.

Bug #: 1403818
Differential Revision: https://phabricator.services.mozilla.com/D149
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.

Summary:
We currently allow sending a "Cancel" message from the child to abort a running
transaction, e.g. when the user switches away from the currently active tab.
We have a message with the same name "Cancel" sent by the parent when the
transaction is aborted due to failure somewhere in the token manager.
This patch renames abort messages from the parent to "Abort" to clarify the
purpose of the message.

This covers these renames:
* In PublicKeyCredentialParameters, algorithm => alg
* MakeCredentialOptions => MakePublicKeyCredentialOptions
* PublicKeyCredentialEntity => PublicKeyCredentialRpEntity
* Attachment => AuthenticatorAttachment
It sets a default excludeList and allowList for the make / get options.
It adds the method isPlatformAuthenticatorAvailable which is incomplete and
not callable, to be completed in Bug 1406468.
Adds type PublicKeyCredentialRpEntity.
Adds "userId" to AuthenticatorAssertionResponse.
Adds "id" as a buffer source to PublicKeyCredentialUserEntity and as a
DOMString to PublicKeyCredentialRpEntity, refactoring out the "id" field
from the parent PublicKeyCredentialEntity.
It also adds a simple enforcement per spec 4.4.3 "User Account Parameters for
Credential Generation" that the new user ID buffer, if set, be no more than
64 bytes long. I mostly added it here so I could adjust the tests all at once
in this commit.

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.

Takes functionality once in the WebAuthentication DOM class that needs
to be handled by the content process, and moves it to a
singleton (per-content-process) manager class. This allows the
WebAuthn API to centralize management of transactions and IPC
channels. Patch also creates the child (content-process) classes for
WebAuthn IPC channels.
