Andrea Marchesini c0dfa196ce Bug 1520150 - Single InputStreams can serialize themselves as IPCRemoteStreams (pipe) - part 2 - IPCRemoteSteam part of InputStreamParams union, r=smaug
Before this patch, IPCStream was an union containing IPCRemoteSteam or an
InputStreamParamsWithFds. Now InputStreamParamsWithFds is renamed IPCStream and
IPCRemoteSteam is one of the possible InputStreamParams structs.
