MediaEngineDefaultAudio uses the SineWaveGenerator and passes a
TrackTicks (int64_t) arg to generate(). It need to take the same type
or bad things can happen.

If a camera returns no capabilities we interpret it as it being able to handle
any capability we throw at it. However, we also end up trying to start it with
the default capability of 0x0@0. This often works, but we can crash when
rescaling it to the chosen target capability 0x0@0.
With this patch we inject up to two default capabilities, one at 640x480@30 and
one at 1280x720@30. With constraints present we'll try to adjust these defaults
so they fit within the constraints while at the same time preserve the
aspect ratio given by prefs.

This will lead to less ipc calls, hopefully speeding up getUserMedia for many
devices.
This also lets us inject any hardcoded capabilities into the candidateSet in
the future (read: next patch).

This adds back the `framerate` update that was removed in bug 1299515.
It also fixes a threading issue (not really an issue, but it broke the
documented policy) where Start() wrote to mCapability without holding mMutex.

Most importantly, this reduces the number of copies to 1 in the common case.
In a case where we are rescaling because there are competing gUM requests
this does two copies, where one is the crop-and-scale operation itself.
In the worst case we do two allocations, but with a buffer pool and a recycling
ImageContainer we allocate very rarely in practice.

Before bug 1299515 we assigned stream and track id in Allocate(), meaning that
any Deallocate() had a guarantee of them being set.
This changed to require an extra step of SetTrack() to assign stream and
track id. Deallocate() needs to handle this, which it does with this patch.

As of bug 1417680, the NSS shutdown tracking infrastructure is unnecessary (and
does nothing anyway). This series of changesets removes the remaining pieces in
a way that is hopefully easy to confirm is correct.

This wires up the disabling of a track with actually stopping the device if we
allow it.
This is possible for:
- Camera (enabled by default, controlled by pref
"media.getusermedia.camera.off_while_disabled.enabled")
- Microphone (disabled by default, controlled by pref
"media.getusermedia.microphone.off_while_disabled.enabled")
Screen-, app-, or windowsharing is not supported at this time.
On disabling, there's a delay before the device is ordered to stop. This is
now defaulting to 3 seconds but can be overriden by prefs
"media.getusermedia.camera.off_while_disabled.delay_ms" and
"media.getusermedia.microphone.off_while_disabled.delay_ms".
The delay is in place to prevent misuse by malicious sites. If a track is
re-enabled before the delay has passed, the device will not be touched until
another disable followed by the full delay happens.

This is the larger change for this bug. In order to turn off a device on
disabling we want to Stop() it without ending the attached track.
To allow this, this patch breaks out track-creation from Start() to SetTrack()
and moves track-ending logic from Stop() to Deallocate().
It is a programming error to Start() or Stop() a MediaEngineSource that hasn't
seen a SetTrack().

The scope of flattening this hierarchy quickly grows large, so this patch does
a couple more things:
- Creates a pure interface MediaEngineSourceInterface and a base class
MediaEngineSource with common defaults and refcount support (no state!)
- Breaks out some of the helper classes to dedicated files, e.g.,
AllocationHandle, MediaEnginePrefs.
- Clarifies the threading model (written on one thread *and* under lock,
read under either)
- Fixes style, indentation, include-sorting in the affected files
- Adds comments, especially for clarifying what responsibilities methods have,
and thread usage of class members
- Changes Monitors to Mutexes since we only use them as Mutexes anyhow
- Makes MediaEngineRemoteVideoSource no longer a shared source since we now
support scaling in this source and CamerasChild can act as a broker of frames.
This greatly simplifies it. The only shared source is now
MediaEngineWebRTCMicrophoneSource, so the sharing specific common methods have
been moved to that source.

This SourceMediaStream is an existing hack to fit AudioCapture into
MediaManager's gUM flow. With the invariant that NotifyPull must produce data
we need to produce silence here.
Best of all would be if this SourceMediaStream was not needed at all, but let's
look at that another time.
