* Initial commit of signal deduper.

Idea is protect against signal storm from misbehaving clients.

Design:
- SignalDeduper interface with one method to handle a SignalRequest and
  return if dupe or not.
- Signal specific deduper. Could have made a single de-duper which could
  handle all signal message types, but making it per type so that the
  code is cleaner.
- Some module (like the router) can instantiate whatever signal types
  it wants to de-dupe. When a signal message is received, that module
  can run the signal message through the list of de-dupers and
  potentially drop the message if any of the de-dupers declare that the
  message is a dupe. Making it a list makes things a little bit
  inefficient, but keeps things cleaner. Hopefully, not many de-dupers
  will be needed so that the inefficiency is not pronounced.

* re-arrange comments

* helper function

* add ParticipantClosed
