Nika Layzell 96d76af151 Bug 1779792 - Part 5: Add a unique nsID field to each MessageChannel pair, r=ipc-reviewers,mccr8
This won't be used for any security or routing purposes, but can be useful for
debugging. It will be used in the future by the profiler to correlate sent and
received message events across processes.
