Step 1+2 of the SDL 3 migration. The 2300-line graphics/glSDL.{c,h}
OpenGL-on-top-of-SDL-1.2 shim is obsolete under SDL 3 (SDL_Renderer
does what glSDL did natively), and its #define overrides of SDL
surface APIs collided directly with SDL 3's SDL_oldnames.h.
- Add graphics/sdl_compat.h: a one-line umbrella that just pulls in
<SDL3/SDL.h>.
- Replace every #include "glSDL.h" with #include "sdl_compat.h" (15
files across the tree).
- Delete graphics/glSDL.c, graphics/glSDL.h.
- Drop glSDL.c from graphics/CMakeLists.txt.
- Remove GFX_DRIVER_GLSDL from the gfx_drivers_t enum and from all
switches/conditions in gfxengine.cpp.
- Drop the glSDL_VSync() call site (will be re-introduced as
SDL_SetRenderVSync once gfxengine is ported to SDL_Renderer).
- Drop the two glSDL_Invalidate() calls in window.cpp (texture
re-upload hints with no equivalent in a pure-surface compositor).
- options.cpp: remove the now-empty "OpenGL/glSDL" menu item; force
videodriver to GFX_DRIVER_SDL2D.
- prefs.cpp: collapse legacy GLSDL setting onto SDL2D on load.
After this commit the macro-collision wall is gone (renamed_-token
errors drop from many to zero). The build still fails on the next
layer of work: SDL 1.2 surface APIs that no longer exist
(SDL_FreeSurface, SDL_SetAlpha, SDL_CreateRGBSurface, SDL_DisplayFormat,
SDL_PixelFormat struct member access, SDL audio callback API, etc.).

Three source patches the modern clang/C++ frontend requires:
- graphics/window.cpp: strchr on const char* now returns const char*
- filemap.cpp, prefs.cpp: C++11 forbids no-space concatenation of a
string literal with an adjacent macro identifier
Autotools state regenerated with autoreconf -fi against current
autoconf/automake so configure can be run on macOS 26 / Apple Silicon.
Added run-kobodl.sh to launch the binary from the source tree (the
compiled-in data paths assume a .app bundle), and a .gitignore for
build artifacts.
Out-of-tree dependency: SDL_image 1.2 must be built with
--disable-imageio. Apple's ImageIO backend in IMG_ImageIO.m yields
SDL_Surfaces with all-zero pixel data on current macOS, leaving every
sprite invisible; libpng decodes correctly.
