Jørgen P. Tjernø e8a48ee6c0 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.

                         Simple DirectMedia Layer

                                  (SDL)

                                Version 2.0

This is the Simple DirectMedia Layer, a general API that provides low
level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
and 2D framebuffer across multiple platforms.

The current version supports Windows, Windows CE, Mac OS X, Linux, FreeBSD,
NetBSD, OpenBSD, BSD/OS, Solaris, iOS, and Android. The code contains
support for other operating systems but those are not officially supported.

SDL is written in C, but works with C++ natively, and has bindings to
several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
Go, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
Pike, Pliant, Python, Ruby, and Smalltalk.

This library is distributed under the zlib license, which can be found
in the file "COPYING".

The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation is available in HTML format in "docs/index.html", and
a documentation wiki is available online at:
	http://www.libsdl.org/cgi/docwiki.cgi

The test programs in the "test" subdirectory are in the public domain.

Frequently asked questions are answered online:
	http://www.libsdl.org/faq.php

If you need help with the library, or just want to discuss SDL related
issues, you can join the developers mailing list:

Enjoy!
