Fixed bug 4108 - Missing break statements in SDL_CDResume and SDL_CDStop

Ozkan Sezer

Two break statements are missing in SDL_cdrom.c:SDL_CDResume()
and SDL_CDStop(), which negate the returned code from driver
and always return 0. The following patch adds those breaks.

Fixed return value

Generalized the handling of instantaneous guide button presses so there's a minimum of 100 ms between guide button press and release.
This happens with at least the following controllers: All Apple MFI controllers, ASUS Gamepad, XiaoMi Bluetooth Controller

Added mapping for the ASUS Gamepad removing the guide button, which doesn't generate events even though it's reported in the Android APIs.

Reimplemented Android cursor API support using reflection so it builds with older SDKs

Added Android custom cursor implementation
This is commented out in SDLActivity.java, with the note #CURSORIMPLEENTATION because it requires API 24, which is higher than the minimum required SDK

Added Mac OpenGL ES configure support

Fixed bug 4102 - define _WIN32_WINNT_WIN7 if not already defined

Ozkan Sezer

The following patch defines _WIN32_WINNT_WIN7 if it is not already
defined in core/windows/SDL_windows.c, similar to what is already
there for _WIN32_WINNT_VISTA.

Fixed bug 4103 - SDL_cpuinfo.h provokes warnings with -Wundef on non-x86 hosts

Felix Geyer

Forwarding from https://bugs.debian.org/892087 quoting verbatim:

The SDL2 header SDL_cpuinfo.h generates gcc warnings if the program using
it compiles with the -Wundef warning. (In particular, this means that QEMU
builds using it fail on at least sparc hosts, since QEMU dev builds
use both -Wundef and -Werror.).

/usr/include/SDL2/SDL_cpuinfo.h:63:5: warning: "HAVE_IMMINTRIN_H" is not defined, evaluates to 0 [-Wundef]
#if HAVE_IMMINTRIN_H && !defined(SDL_DISABLE_IMMINTRIN_H)

Fix ARM builds with MSVC
