This patch adds a new IPDL protocol PBackgroundLocalStorageCache. It is used by LocalStorageCache object to broadcast changes in local storage cache to other content processes. Each origin has its own PBackgroundLocalStorageCache, so now we can notify content processes that actually have a local storage cache for given origin. This greatly improves performance and reduces memory footprint especialy when local storage changes carry big strings and/or happen very quickly (before this patch all child processes were blindly notified).
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 that was in the WebAuthentication class that now
needs to be handled by the parent process, and moves it to the
U2FTokenManager singleton class. U2FTokenManager is created on the
PBackground thread during the first WebAuthn transaction, and manages
hardware access and transaction management for the lifetime of the
browser session. Patch also adds parent classes for WebAuthn IPC
protocol.

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.
