Add logging was added to help diagnose gUM failures and provide more log
coverage of that code path.

The previous assertion was from an earlier developer stage which changed
during development of bug 1299515. It assumed that mDeviceEnabled was
updated only after passing the assert.
In the final version of bug 1299515 that is no longer true, and
both the failed and the successful device operation asserts
can now be unified to one.

With the added invariant that NotifyPull() needs a MediaStreamListener present
to not underrun, we need SetPullEnabled() and AddListener() to stay in sync by
using the same signaling mechanism.

This modifies mediaCaptureWindowState() to say whether a camera or microphone is
actively captured or not. Note that this is not the same as the device being
on or off. If we disallow a device from being off while disabled, we still
notify chrome that we're not actively capturing.

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.

Currently we run the risk of missing MediaManager::OnNavigation() at shutdown in
some cases. When it happens, cleanup of window listeners is delayed to
MediaManager::Shutdown().
Triggering window listener shutdown through the destructor doesn't work when the
destructor is invoked by WindowTable::Clear(), as clearing out the
window listener's SourceListeners will trigger a call back into
WindowTable::Remove() to remove the now empty window listener.
This is not allowed by the hash table implementation.
This patch fixes this by changing strategy from cleanup-in-dtor to explicit-cleanup-before-dtor and making a non-clean state in the dtor an error.

This delays setting sInShutdown (renamed to sHasShutdown for better semantics)
until all that remains of shutdown is to shut down the media thread.
From JS this is no change as JS cannot run until Shutdown() is done.
The difference is that we let members and still-active listeners get destroyed
and cause any members that are media-thread only (in this case devices), to shut
down before the thread goes away.

These were originally exposed directly as static methods on nsGlobalWindow, but
as they are clearly associated with either the inner or outer window, it makes
more sense for them to be called as such.

This is a large patch which tries to switch many of the external consumers of
nsGlobalWindow to instead use the new Inner or Outer variants.
