- 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.

- I have refactored the Oculus and OpenVR interfaces in gfx/vr
so that initialization of the VR libraries only happens once
a WebVR site is detected.
- The Oculus interface has been cleaned up and updated to unload the Oculus
runtime library when not in use.
- The browser can now re-connect to Oculus home if it was restarted, without
restarting the browser.
- We no longer submit a black frame at the end of VR presentation, as this
appears to be handled by the latest Oculus runtime automatically.
- As we only hold on to the Oculus runtime when needed, this should
reduce the likelihood of the GPU process being killed by the Oculus
software updater.
