The following patch adds Metal.framework to the "link binary with libraries" section of each test program, with "status" set to "optional", which fixes link errors on all of the test programs. I'm not sure if this is a correct fix - the fact that this was necessary might indicate the static SDL2.a library has a hard dependency on Metal.framework (?) - but it gets the test programs working in Xcode again.
It also adds testyuv_cvt.c to the testoverlay2 target, fixing a link error.

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

We need to use GLES2 to implement true cross-platform code.
New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

Xcode 9 emits a warning to validate project settings. The changes it proposes are
1. [iOS] Update the iOS deployment target to 8.0 since Xcode does
not support anything older.
2. [macOS] Target 'Framework' - Automatically Select Archectures.
3. [iOS & macOS] Turns on a bunch more compile warnings, a *lot* more on iOS.
4. [iOS & macOS] Turn on "Missing Localizability".
I want to confirm if it is ok to accept these changes and submit updated project files.
Since Alex Szpakowski has just removed iOS 7 guard ifdef's, I'm guessing 1 isn't a problem.
2 is probably ok for anyone building themselves. I wonder if it may cause problems for building distribution binaries.
3 shouldn't be a problem either provided any newly emitted warnings are fixed.
4 I am unfamiliar with. The description says "This will turn on the static analyzer to check for "Missing Localizability", because this project is localized for multiple languages." I suppose this may cause new warnings.
I think this was important for SDL 1.2 because some targets needed
special device memory for DMA buffers or locked memory buffers for use in
hardware interrupts or something, but since it just defines to SDL_malloc
and SDL_free now, I took it out for clarity's sake.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
