- Ensure ovr_GetSessionStatus is polled even when a VR presentation
is not active.
- When we fail to initialize an Oculus Session or detect VR hardware,
immediately unload the Oculus Library as we can't poll for ShouldQuit
without a valid Oculus session.
- When we poll ovr_GetSessionStatus, we are now updating the mounted state
in VRDisplayInfo::mIsMounted.
- Added prefs to control enumeration throttling and timeout to release
VR hardware when inactive.
- Some refactoring to make frame loop more understandable and less
brittle.
- When throttling enumeration, we ensure that all other VR apis
also throttle enumeration so that they don't pick up the same device
during throttling.
- Some long functions in VRManager have been broken up and
had their inner-workings documented in more detail.

This was previously limited to 2 per principal and 4 total on
mobile. Mobile GPU drivers have progressed a lot since the limit was
put in place, and the strict limit is causing webcompat issues on
google maps.
Increase to 8 per principal and 16 in total, bringing us
closer in line with Chrome. Make these limits contrallable via a pref
so that if there are any problems it is easy to change.

- As we are creating a separate VR process in Bug 1362578,
we will need our own D3D11Device.
- Eventually, we will be allowing the VR device runtimes to
help select the appropriate adapter / device based on the
physical connection. This function will be updated at that
time.

High resolution, high framerate was disabled by default on old AMD cards on the provisio that it was bad. But this assumes that the CPU decoder could do it better.
This assumption appears fragile at best, as CPU with those old adapter are likely to be old and underpower to start with.
Chrome doesn't appear to restrict use of those cards to a given resolution.
So we disable this restriction, while making it user configurable.

Setting the 'layout.display-list.retain.verify' gfxPrefs implies
'layout.display-list.build-twice', and then compares the retained-built tree
to the non-retained one, and outputs differences&trees to the terminal.

Factory::DoesBackendSupportDataDrawtarget already fulfills the same
purpose and we should use that instead, as imgFrame is the only user of
the former API. It has the added bonus of allowing us to use shared
surfaces on Linux with WebRender, and using volatile surfaces on Windows
when D2D is disabled.
moz_posix_memalign is a wrapper for posix_memalign that only exists if
posix_memalign exists.
On OSX, it has a fallback for an under-specified bug where it
purportedly returns a pointer that doesn't have the requested alignment.
That fallback was added in bug 414946, over 6 years ago, before jemalloc
was even enabled on OSX.
Considering posix_memalign is used directly in many other places in
Gecko, that we almost always use mozjemalloc, which doesn't have these
problems, and that in all likeliness, the bug was in some old version of
OSX that is not supported anymore, the fallback does not seem all that
useful.
So, just use posix_memalign directly.

This commit removes the `layers.omtp.force-sync` preference and replaces
it with a preprocessor define that is commented out. This commit also
changes the behavior of force-sync so that it also does synchronization
with CompositorBridgeChild like normal OMTP. This simplifies the code
and makes using a preprocessor define easier.

The code in ComputeSuitableScaleForAnimation feeds its double-based
computation results into GetSuitableScale, which takes and returns
floats. Also the double-based computation that it's doing involves
calling UpdateMinMaxScale a bunch which explicitly uses the float
variant of std::min and std::max. And all of this is used from
ChooseScaleAndSetTransform which does other things like call a
"RoundToFloatPrecision" function, and casts the final values to
floats before setting the layer's prescale. So let's just use
floats all the way through.
