commit 18addc1ee2e63344ce882005e48c2e509a7402b5

VR: Split off UI code into a library to ease future unit testing.

This new library contains most "utility" and UI code, which is platform
independent and easily testable.  The original library contains core,
Android, threading, etc.  This is a step towards being able to build a
small unit test binary, and run it on Linux.

To allow the split, add a GL renderer interface to hide the GL thread
from UI elements.

commit a6215bc06ce7fc233fe1cedab27988d6cbd5b9c4
Author: Christopher Grant <cjgrant@google.com>
Date: Tue Jun 06 16:05:11 2017

VR: Further split common code from Android-specific code.

Separate the UI to browser interface, to drop all Android awareness.
Also, fix a few instances of code that doesn't compile on linux.

The only thing needed now to compile tests on linux is a reference from
src/BUILD.gn, and exposing a few libraries and string resources exposed
to linux.
