This is where Apple installs XQuartz now (and apparently, the compatibility
symlink at /usr/X11R6 can be missing).
Fixes Bugzilla #4706.

Current code, search paths, and error messages are written to only consider MoltenVK on macOS as a Vulkan Portability implementation. It's not the only implementation available to the users. gfx-portability [1] has been shown to run a number of titles well, including Dota2, Dolphin Emulator, and vkQuake3, often out-performing MoltenVK in frame rate and stability (see Dolphin benchmark [2]).
There is no reason for SDL to be that specific, it's not using any MVK-specific functions other than the WSI initialization ("VK_MVK_macos_surface"). gfx-portability exposes this extension as well, and a more generic WSI extension is in process. It would be good if SDL was written in a more generic way that expect a Vulkan Portability library as opposed to MoltenVK specifically.

This isn't complete, but is enough to run testsprite2. It's currently
Mac-only; with a little work to figure out how to properly glue in a Metal
layer to a UIView, this will likely work on iOS, too.
This is only wired up to the configure script right now, and disabled by
default. CMake and Xcode still need their bits filled in as appropriate.

Seems latest google angle library successfully built & tested under macOS'es.

We need to use GLES2 to implement true cross-platform code.

When RWops seeks with fseek or fseeko it uses the types long or off_t which can be 32 bits on some platforms. stdio_seek does not check if the 64-bit integer for the offset fits into a 32-bit integer. Offsets equal or larger than 2 GiB will have implementation-defined behavior and failure states would be very confusing to debug.
The attached patch adds range checking by using the macros from limits.h for long type and some bit shifting for off_t because POSIX couldn't be bothered to specify min and max macros.
It also defines HAVE_FSEEKI64 in SDL_config_windows.h so that the Windows function gets picked up automatically with the default config.
And there's an additional error message for when ftell fails.

Cmake checks for float.h, but configure does not: the attached patch
adds float.h to checked headers in configury, and it adds the missing
HAVE_FLOAT_H macro to SDL_config.h.cmake and SDL_config.h.in.
In SDL_config_macosx.h and SDL_config_windows.h, defined HAVE_FLOAT_H
as 1, where I know that it's true.
This work was done by Jacob Lifshay and Mark Callow; I'm just merging it
into revision control.

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.
I think you'll need to install Xquartz, the external-but-official replacement
for Apple's X11, to get the Xlib headers: http://support.apple.com/kb/HT5293

2.Replaced XKeycodeToKeysym with XkbKeycodeToKeysym since XKeycodeToKeysym is deprecated in newer X11 version
3.Rewrote testime.c since it was disabled after SDL_compat.c removal
4.Take into account common arguments also in testrelative.c
