56363ebf61 Fixed bug 3690 - SDL2 KMS/DRM render context support
Manuel

The attached patch adds support for KMS/DRM context graphics.

It builds with no problem on X86_64 GNU/Linux systems, provided the needed libraries are present, and on ARM GNU/Linux systems that have KMS/DRM support and a GLES2 implementation.
Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition.
X86 systems use KMS right away in every current GNU/Linux system.

Simple build instructions:

$./autogen.sh
$./configure --enable-video-kmsdrm
$make

67ed894353 Fixed bug 3529 - SDL_EGL_UnloadLibrary is not called at all on SDL_Quit
kaisyu

In case of OpenGLES, the sequences of loading and unloading driver library should be like that:

SDL_Init
  ...
  SDL_GL_LoadLibrary
    SDL_EGL_LoadLibrary
...
SDL_Quit
  ...
  SDL_GL_UnloadLibrary
    SDL_EGL_UnloadLibrary
...


However, according to my test results, the varible '_this->gl_config.driver_loaded' does not allow 'SDL_GL_UnloadLibrary' to call 'SDL_EGL_UnloadLibrary'.

0cfa0aa11c improved SDL_GetError() output generated by EGL code
This change attempts to report the EGL error codes generated by SDL's calls
into EGL, along with the name of the EGL function that failed.

748b05289c EGL: Fixed SDL_GL_GetSwapInterval() returning -1 on error.
It should return 0 as a safe default on errors. -1 is returned for late swaps.

0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later.
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().
