Even if we're blitting between two different surfaces their pixels might still overlap, because of SDL_CreateRGBSurfaceFrom(), so always use SDL_BlitCopy() and check for overlap in that function.
When handling overlapping surfaces, don't assume that memcpy() iterates forward, instead use memmove() correctly, and provide a fallback implementation of SDL_memmove() that handles the different cases.
Fixed a bug with SDL_memset() not completely filling lengths that aren't a multiple of 4.
Optimized SDL_memcpy() a bit using the same technique as SDL_memset().

Currently SDL_JOYSTICK_DEVICE environment variable can be used to add
exactly one topmost device. I think it would be nice if one could also set
several devices (e.g. a stick and a throttle) in this way, as a colon-
separated list. The attached patch implements this

Fix segfault in ALSA_OpenDevice()
When alsa is linked to libsdl instead of being loaded on demand at runtime the
alsa macro snd_pcm_hw_params_alloca(ptr); misbehaves.
That macro calls snd_pcm_hw_params_sizeof() in order to determine the amount of
memory to allocate but due to mis-placed define that function is replaced with
ALSA_snd_pcm_hw_params_sizeof by preprocessor (and in case of link to alsa that
function pointer is initialized to itself).
Attached patch fixes the issue.
The trick is that if you're using configure and you don't want to have SDL_config.h and SDL_revision.h to show up as modified, you need to configure and build from a separate directory.
You also need to include SDL_revision.h directly if you want to use the SDL_REVISION constant, as a side effect of these changes.
The render viewport is automatically re-centered when the window changes size, so applications that don't care will not have to handle recalculating their rendering coordinates.
Fixed API for drawing and filling multiple rectangles - the parameter should be an array of rects, not an array of pointers to rects.
Fixed API for updating window rects for consistency with other APIs - the order is pointer to array followed by count in array.
Migrate all of the recent changes into the SDL VS2005 project file.
Fix missing return value in SDL_pixels.c
Fix compile error in testscale.c, variable was incorrectly named.
Added VS2005 project file for testscale

Patch attached. The renderer for the DS is not used anymore, but I left the
file in place if someone wants to finish it.
I've also added a README.ds and fixed the spinlocks.
Fixed creating render texture framebuffer.
Removed the need for palette watch, added surface format caching.
Added an SDL_DONTFREE flag so you can't free the window and 1.2 shadow surfaces.
There's a new event that's always sent when the window changes size, and that event is what the renderers listen for to determine if they need to rebind their context.
