This was needed to make stratosphere buildable with debugging on. os:: assertions rely on GetCurrentThread() working, and this requires the global os resource manager to be constructed. However, __appInit executes before global constructors. We now require that hos::InitializeForStratosphere() be called before anything else is done. This initializes the os resource manager, sets the hos version for libnx, and may do more things in the future. TODO: Consider replacing __appInit/__appExit with ams:: namespace functions in general, and wrap them so that we guarantee hos::InitializeForStratosphere is called first, and generally ensure a consistent stratosphere environment.
