  configuration updates for dlopen: - cmake, configure (CheckDLOPEN): --enable-sdl-dlopen is now history.. detach the dl api discovery from SDL_LOADSO_DLOPEN functionality. define HAVE_DLOPEN. also define DYNAPI_NEEDS_DLOPEN (CheckDLOPEN is called only for relevant platforms.) - update SDL_config.in and SDL_config.cmake accordingly. - SDL_dynapi.h: set SDL_DYNAMIC_API to 0 if DYNAPI_NEEDS_DLOPEN is defined, but HAVE_DLOPEN is not. - pthread/SDL_systhread.c: conditionalize dl api use to HAVE_DLOPEN - SDL_x11opengl.c, SDL_DirectFB_opengl.c, SDL_naclopengles.c: rely on HAVE_DLOPEN, not SDL_LOADSO_DLOPEN. - SDL_config_android.h, SDL_config_iphoneos.h, SDL_config_macosx.h, SDL_config_pandora.h, and SDL_config_wiz.h: define HAVE_DLOPEN. Closes: https://github.com/libsdl-org/SDL/pull/4351

  /* IMPORTANT:
     This is the master switch to disabling the dynamic API. We made it so you
     have to hand-edit an internal source file in SDL to turn it off; you
     can do it if you want it badly enough, but hopefully you won't want to.
     You should understand the ramifications of turning this off: it makes it
     hard to update your SDL in the field, and impossible if you've statically
     linked SDL into your app. Understand that platforms change, and if we can't
     drop in an updated SDL, your application can definitely break some time
     in the future, even if it's fine today.
     To be sure, as new system-level video and audio APIs are introduced, an
     updated SDL can transparently take advantage of them, but your program will
     not without this feature. Think hard before turning it off.
