IPC stream feature should use client/server naming instead of sender/receiver
Originally the feature was implemented with names using "sender" and "receiver".
However, at the landing time the naming was changed to use "client" and "server" to follow the existing IPC::Connection.
However, not all the names were changed consistently.
Change all the names to use "client" instead of "sender" and "server" instead of "receiver".
