Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.
- VRManagerChild no longer needs to be a TextureForwarder
- VRManagerParent no longer descends from HostIPCAllocator or ShmemAllocator
- PVRManager no longer manages PTexture's
- VRLayerParent::mSize was not used and has been removed

- WebVR is no longer dependent on PTexture, TextureParent,
TextureHost, and TextureChild. It continues to use TextureClient
for pooling and coordinating locks with other Gecko code.
- PreserveDrawingBuffer now behaving correctly for 2d display mirroring
- Preparation for separating to VR process

- A user gesture is required only for the VRDisplay.requestPresent
call that initiates the VR presentation, as per the WebVR 1.1 spec.
- The parameters of the VRLayer can now be updated by calling
VRDisplay.requestPresent on an active VR presentation.
- Dynamic resolution switching is now functional:

From the crashes associated with bug 1389021, we know that some
compositor thread IPDL owners are not being cleaned up properly. We do
not know which protocols are causing the problem, so we temporarily will
annotate the logs with the ownership status. This should be limited to
under a dozen instances of the protocols.
This change will be backed out after a few builds are produced with it
and we see the first crash reports with the relevant data.
- In VRManagerChild::DeallocPVRLayerChild, we delete the PVRLayerChild, rather
than doing proper reference counting on the VRLayerChild object which has
been deallocated but still referenced by VRDisplayPresentation::mLayers.
This happens when the GPU process is terminated.
- When the user tries to stop the VR presentation or change the URL,
PVRLayerChild::SendDestroy is called by VRDisplayPresentation::DestroyLayers.
This results in the assertion about "invalid actor state".
- This patch fixes this by following the same pattern used by TextureClient
for its PTextureChild.

- Now destroying and re-creating Oculus sessions when switching
between magic window and immersive WebVR (BeginPresent / ExitPresent)
- Now sending flags to Oculus ovr_initilize to specify if Firefox will
be presenting to the VR display or just using tracking
- Now coordinating oculus session shutdown and restart between the
VR controllers and the VR display with reference counting.
- Now able to return to Oculus home after using WebVR
- Magic window / non-exclusive sessions no longer take over the VR headset
causing it to display a message that Firefox.exe is not responding.

- Added new chrome-only webidl methods to be used by browser UI and WebExtensions
- Implemented bitmasked group visibility for VR sessions to enable switching
between chrome and regular content presentations.
- Implemented throttling mechanism to avoid runaway, unthrottled render loops
for VR sessions that are hidden by group visibility bitmasks or due to
lower level platform VR events, such as during the Oculus
"Health and Safety Warning".
- Simplified the PVRManager IPC protocol while extending it to support
VR session groups and later WebVR content performance profiling API's.
- Removed the last WebVR related sync IPC call.

- PVRManager::GetDisplays was a sync IPC that was part of an optimization
for a use case that has been eliminated by changes to the WebVR spec.
- This was an optimization for Navigator.activeVRDisplays that would allow
enumeration of displays active in any content process without powering
on any additional VR hardware. This will no longer be necessary as the
activeVRDisplays has been restricted to returning only the displays
active in the current javascript context.
