f85aeb98c7 Don't clobber refcounting in SDL_Init. 
- Fixes bug 1712 by not overwriting SDL_SubsystemRefCount in SDL_Init.
       - Removes the SDL_initialized variable, and makes SDL_SubsystemRefCount
         the canonical source of truth for whether or not a subsystem has been
         initialized.
       - Refactors SDL_InitSubSystem and SDL_QuitSubSystem to use helper
         functions to manage refcount.
       - Adds automated tests for SDL_Init/Quit*.
       - Adds SDL_bits.h which contains SDL_MostSignificantBitIndex.
