...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)

Implement speakerphone toggle directly. Previously we were using
AppAudioManager for several things, but this is that last lingering bit.
Much of the AppAudioManager code is based on RedPhone calling, so by
removing the dependency we pave the way to throw that code away.

8 Cases considered:
(Silent Switch toggled vs. Silent Switch not-toggled)
x (App in Foreground vs. App in Background)
x (CallKit vs. NonCallKit)
CallKit already does the "right thing"

There isn't much the user can do in response to it, and the user will
get a subsequent "new message" notification when the fallback push
triggers.

Because logging-preference was previously stored on the storageManager
this meant we couldn't possible log anything related to the init'ing the
storage manager.
TODO: migrate old logging preference to use the new NSUserDefaults
setting

Most likely this would be because the user hasn't unlocked their device
since last restart.
This behavior existed once before, but the startup ordering is pretty
delicate. So, we're now redundantly checking in SSK in case this
delicate startup logic gets mis-ordered again.
Also fixed the AppDelegate method to check for the proper
applicationState, since it will never be "active" in didFinishLaunching.

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)
