This requires quite a bit of piping to get the ChildID passed everywhere where we currently pass the pid in IPC. This is done by adding a new struct type (EndpointProcInfo), which is passed around instead of OtherPid in these places, and contains the full pid. In most cases, it was a fairly painless change to move over, however in some cases, more complex changes were required, as the pid was being stored previously in something like an Atomic<...>, and needed to be switched to using a mutex-protected value. In the future, it may be possible to remove OtherPid from IPDL actors once everything is migrated to ChildID, but we're still a long way off from that, so for now we unfortunately need to pass both around.
