This interface will allow extensions running into a content process to attach
a filtering stream listener to an HTTP request in the parent process. The
content process attaches a listener by sending a message from the content
process containing the ID of the request to filter, and the ID of the add-on
making the request. The permissions and request mappings for this are handled
by the web request service added in part 2.

PHttpBackgroundChannel is created by content process because PBackground IPDL
can only be initiated from content process. The background channel deletion is
controlled by chrome process while PHttpChannel is going to be closed or canceled.
BackgroundChannelRegistrar is introduced for pairing HttpChannelParent and
HttpBackgroundChannelParent since they are created over different IPDL
asynchronously.
nsIParentRedirectingChannel.continueVerification is introduced to asynchronously
wait for background channel to be established on the new channel during the
Redirect2Verify phase.

PHttpBackgroundChannel is introduced to deliver OnStopRequest/OnTransportAndData/OnProgress/OnStatus on background thread.
FlushedForDiversion/DivertMessages is moved to PHttpBackgroundChannel to ensure no more channel event are delivered after these two messages on the background channel.
OnStartRequestSent is introduced to synchronize the execution order between OnStartRequest (main thread IPC) and all other messages on PHttpBackgroundChannel.

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.

IPCBlobInputStream is a new type of nsIInputStream that is used only in content
process when a Blob is sent from parent to child. This inputStream is for now,
just cloneable.
When the parent process sends a Blob to a content process, it has the Blob and
its inputStream. With its inputStream it creates a IPCBlobInputStreamParent
actor. This actor keeps the inputStream alive for following uses (not part of
this patch).
On the child side we will have, of course, a IPCBlobInputStreamChild actor.
This actor is able to create a IPCBlobInputStream when CreateStream() is
called. This means that 1 IPCBlobInputStreamChild can manage multiple
IPCBlobInputStreams each time one of them is cloned. When the last one of this
stream is released, the child actor sends a __delete__ request to the parent
side; the parent will be deleted, and the original inputStream, on the parent
side, will be released as well.
IPCBlobInputStream is a special inputStream because each method, except for
Available() fails. Basically, this inputStream cannot be used on the content
process for nothing else than knowing the size of the original stream.
In the following patches, I'll introduce an async way to use it.
We will use the new type for the generated IPDL message handler
prototype to make sure correct error handling method is called.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This allows us to send a sync fork request to the Nuwa process when we need one but there is no
spare process available. After an app is launched, the request to fork a spare process is still
handled asynchronously.
