Valentin Shergin 7df58e23a3 Introducing RCTSurface, new experimental thread-safe interop layer
Summary:
RCTSurface instance represents React Native-powered piece of a user interface
which can be a full-screen app, separate modal view controller,
or even small widget. It is called "Surface".

The RCTSurface instance is completely thread-safe by design;
it can be created on any thread, and any its method can be called from
any thread (if the opposite is not mentioned explicitly).
The primary goals of the RCTSurface are:
 - ability to measure and layout the surface in a thread-safe and synchronous manner;
 - ability to create a UIView instance on demand (later);
 - ability to communicate the current stage of the surface granularly.
