Andrea Marchesini bb51c49f4f Bug 1353629 - PBlob refactoring - part 3 - IPCBlob in ClonedMessageData, r=smaug ...

This is the first use of IPCBlob: ClonedMessageData.
ClonedMessageData is used for BroadcastChannel, MessagePort and any
postMessage() communication. This patch changes StructuredCloneData in order to
use IPCBlob instead of PBlob.
BroadcastChannel has a custom way to manage Blobs because when the parent
receives them from a content process, it must send them to any other
BroadcastChild actor duplicating the serialization.
