Summary:
This is only the core C++ part of TurboModule - moving to github to make integration with existing NativeModules system slightly easier. Other bindings for iOS/Android are not yet ready to move.
Notes:
* TurboModules is not ready to use at the moment.
* Build configuration is not yet provided (cocoapods/.xcodeproj/gradle), just like Fabric.
* No effort was done to make this lib C++17 strictly compliant yet (there will be in the future).

Summary:
This diff fixes a race condition that was detected on "Marketplace You" production test for Android.
The race condition happens when the method ShadowTree::complete is executed concurrently from two threads (in this case this is called from Scheduller::constraintSurfaceLayout and Scheduler::uiManagerDidFinishTransaction), based on the order of execution this bug makes MountViewItems to be dispatched to the UI in the wrong order.
The root cause of the bug is in the method:
```
bool ShadowTree::complete(
const SharedRootShadowNode &oldRootShadowNode,
const UnsharedRootShadowNode &newRootShadowNode) const {
newRootShadowNode->layout();
newRootShadowNode->sealRecursive();
auto mutations =
calculateShadowViewMutations(*oldRootShadowNode, *newRootShadowNode);
if (!commit(oldRootShadowNode, newRootShadowNode, mutations)) {
return false;
}
emitLayoutEvents(mutations);
if (delegate_) {
delegate_->shadowTreeDidCommit(*this, mutations);
}
return true;
}
```
Notes:
- the commit method is guarded by the commitMutex_
- the shadowTreeDidCommit() method dispatches mutations instructions to the platform side.
- If there are two threads running concurrently, there is no guarantee that the shadowTreeDidCommit() is going to be called in the correct order.
The solution is to include the execution to shadowTreeDidCommit() in the same commitMutex_
Possible solutions:
1 - move the commitMutex_ out of the commit method (to the completeMethod)
2 - synchronize the call to complete method() - this is the implemented solution.
I chose this solution to make it consistent with the way Scheduler::constraintSurfaceLayout is implemented (https://fburl.com/8l49no5x)
This mechanism is very likely to change in the refactor of threading mechanism that Valentin Shergin is going to be working on January.
I would like to land this, so we can fix this bug and run another experiment in production as soon as possible.

shergin mentioned that he'd like to move away from RTTI a bit and use explicit key strings for context container instances rather than relying on the `typeid`, so this does this.
We also fatal with a useful error message if we get a collision, rather than failing silently.

Summary: We need a way for different apps to inject dependencies or additional functionality into Fabric - ReactNativeConfig might be a special case, but I think this could clean up it's integration nicely, and I'm using this for a uitemplate cache system so we can use CompactDisk or other storage systems for caching depending on the app.

`CompactValue` represents a `YGValue` in 32bits instead of 64. This comes at the cost of a range limitation, as one exponent bit is borrowed for the unit.
*Undefined* and *Auto* have no magnitude, and are represented as *NaN* values.
The data structure is meant to be used as a field type on `YGStyle` to save memory.
This is header-only for efficient inlining.

Summary:
I've noticed that when a child's size is determined by `align-items: stretch` in combination with `aspect-ratio` its size is wrongly calculated to account for margin in the main axis when there is more than enough space.
See playground: https://goo.gl/tgW6cD
I've yet to figure out exactly how to solve this but i've started by writing a failing test when can be seen in the first commit here.
I assumed I had found the bug here https://github.com/facebook/yoga/blob/master/yoga/Yoga.cpp#L1838 where margin is being subtracted from the desired width even though the measure mode tells it to measure to exactly that size. However, if we don't remove this margin from the available width then 15 tests fail (including the one I just added) not quite figured out why yet. I'm also a bit confused at to why this would only happen for nodes with `aspect-ratio` and not for nodes where an explicit height and width is set.
