Distinguish between localHangup, remoteHangup, and call failure.
This allows us to put CallKit in the proper state, ready to receive new
calls without having a backlog of phantom calls which haven't been
properly removed.
Note the "call error" occurs at the point ICE fails, which takes a
while. Anecdotally, like 10 seconds, which feels like a long to be
talking into the ether.
I briefly considered failing at 'disconnected', which happens much
sooner, but that's actually a recoverable state. E.g. if you toggle
airplane mode you can see that you bounce into `disconnected` and then
back to `connected`, so I don't think we'd want to fail the call as long
as WebRTC considers it "recoverable".

...in response to CR, move the AudioService off of the CallViewController
Adopt multiple observer pattern vs. a singular delegate. Doing so
required implementing some machinery to address the ARC (see:
Weak.swift)
// FREEBIE
We do this by manually managing the RTCAudioSession.
Unfortunately to do this we have to include a couple of RTC headers not
exported by the default build of WebRTC.framework (see: Libraries/WebRTC)
// FREEBIE
This makes sense as PeerConnectionClient is our interface to WebRTC
- Makes it easier to test PeerConnectionClient and CallService
- Allows us to shrink CallService class a bit (it's huge)

* Ensure NotificationsManager has dependencies
Otherwise it's easy to mess up the order of the required dependencies.
* move AccountManager into Environment, it's heavy to construct
// FREEBIE
* Add generated Signal-Swift.h to test search header path. You must do
this when testing an ObjC clas with swift dependencies (PushManager. in this case)
* Word on the street is that XCode8.2 is less flaky for running simulator tests
