(we always dynamically load it at runtime when appropriate.)

This was the only thing that made SDL_config.h generate differently between
32 and 64-bit versions of Linux, so instead we force a function cast in our
X11 code to match our dynamic loader version, which removes the compile error
on some machines that prompted this test in the first place.
Xlib never wrote to this data, so if you're on an older Xlib where this param
wasn't const, your data should still be intact when we force the caller to
think it was actually const after all.
Fixes Bugzilla #1893.

Apparently -ObjC works with Clang, but -x objective-c works with both.

Bumped required CMake version to 2.8.
Thanks to the SDL/Emscripten porting team for this cleanup.

this patch adds a check to the CMake build script to detect whether the VideoCore API is available.
If it is found, it enables SDL_VIDEO_DRIVER_RPI and will also add the needed include/library directory flags to CMAKE_C_FLAGS so the subsequent check for GLES succeeds in picking up the headers.
Seems to work fine on Raspbian.

Since changeset 358696c354a8, SDL 2.0 has been broken on Solaris when compiling with the Solaris Studio compiler (which uses the pthread implementation of SDL_AtomicLock).
Notably, it gets stuck at the MemoryBarrierRelease in SDL_GetErrBuf:
6585 # 218
6586 if (!tls_errbuf && !tls_being_created) {
6587 SDL_AtomicLock_REAL ( & tls_lock );
6588 if (!tls_errbuf) {
6589 SDL_TLSID slot;
6590 tls_being_created = SDL_TRUE;
6591 slot = SDL_TLSCreate_REAL ( );
6592 tls_being_created = SDL_FALSE;
6593 { SDL_SpinLock _tmp = 0 ; SDL_AtomicLock_REAL ( & _tmp ) ; SDL_AtomicUnlock_REAL ( & _tmp ) ; };
^^^ loops forever above
6594 tls_errbuf = slot;
6595 }
6596 SDL_AtomicUnlock_REAL ( & tls_lock );
6597 }
Running: testthread
(process id 28926)

As far as I can tell, this is because pthread_spin_trylock() always returns EBUSY for this particular lock; since it works in other places, I'm suspicious.
Different Solaris Studio compiler versions seem to make no difference.
I've verified this is broken on Linux as well if SDL_spinlock.c is modified to use the pthread implementation.
This appears to be because pthread_spin_init() and pthread_spin_destroy() are not used with the locks as required.

Based on the original port to Wayland by: Joel Teichroeb, Benjamin Franzke, Scott Moreau, et al.
Additional changes in this commit, done by me:
* Wayland uses the common EGL framework
* EGL can now create a desktop OpenGL context
* testgl2 loads GL functions dynamically, no need to link to libGL anymore
* Assorted fixes to the Wayland backend
Tested on the Weston Compositor (v1.0.5) that ships with Ubuntu 13.10,
running Weston under X. Tests ran: testrendercopyex (all backends), testgl2, testgles2,testintersections

We don't clash with Xlib symbols anymore.

Haiku uses most of the standard pthread API, with a few #ifdefs where we
still need to fallback onto the old BeOS APIs.
BeOS, however, does not support pthreads (or maybe doesn't support it well),
so I'm unplugging support for the platform with this changeset. Be Inc went
out of business in 2001.

The autotools-based code uses X_CFLAGS and some hackish x_includes code to add some necessary includes to SDL_CFLAGS for proper X11 and OpenGL include handling.
At the moment, the cmake-baed build code does not do that. Below is a patch, which provides the necessary changes to add a proper include to the SDL_CFLAGS.

My recent change broke the sdlcheck.cmake by not escaping some quotes properly.
Thanks to Marcus von Appen for pointing it out and providing the patch.

This #errors if you're using an SDK or deployment target that is less
than 10.6 and 10.5, respectively, and cleans up uses of
MAC_OS_X_VERSION_MIN_REQUIRED and MAC_OS_X_VERSION_MAX_ALLOWED according
to those requirements.
