Move setlocale(3) and the wchar stubs over to .cpp.
Also separate out the C++ files so we can use -Werror on them. I'd rather wait for LOCAL_CPPFLAGS to be in AOSP, but this also lets us see which files still need to be sorted into one bucket or the other. Change-Id: I6acc1f7c043935c70a3b089f705d218b9aaaba0a
