Cervantes Yu b2307503dd Bug 1155547, Part 2: Create PNuwa protocol (managed by PBackground) for forking content processes. r=khuey
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.
