224aa45b59 kmsdrm: Implement GL_DefaultProfileConfig for Raspberry Pi compatibility. 
If we think this might be a Raspberry Pi device, default to ES2. Otherwise,
accept SDL's higher-level defaults.

155fdc7ac0 kmsdrm: settle with first card that has a connected connector 
Previously the first card with non-empty connectors, encoders
and crtcs would be selected, however KMSDRM_VideoInit could still reject
it if the connector was not connected. This allow finding the first card
(in a multi GPU setup) that is actually connected to a display.

052a13738d Merge VideoBootStrap::available into VideoBootStrap::create 
The two are only ever called together, and combining them makes it possible
to eliminate redundant symbol loading and redundant attempts to connect
to a display server.

b9f55b6d80 Fixed bug 5199 - Fix KMSDRM_CreateWindow() segfault when starting L?VE2D engine. 
Manuel Alfayate Corchete

This small patch fixes the KMSDRM_CreateSurfaces() call in KMSDRM_CreateWindow(), that was segfaulting deeper into SDL internals because the windata->viddata pointer wasn't set before the KMSDRM_CreateSurfaces() call.
So that's what this small patch does.

Now, L?VE2D works perfectly well on the Raspberry Pi 3, instead of just segfaulting.

d48c97c4a4 Fixed bug 5147 - KMSDRM: SetWindowFullscreen() failing with SDL_WINDOW_FULLSCREEN_DESKTOP 
Manuel Alfayate Corchete

This patch is needed so programs that do this work as expected:
1) Start in a different video mode than the mode used by the system and then...
2) Try to go fullscreen with the mode originally used by the system via SetWindowFullScreen() with the SDL_WINDOW_FULLSCREEN_DESKTOP flag.

An example would be pt2-clone in https://github.com/8bitbubsy/pt2-clone.
This program does this:

Starts with:

video.window = SDL_CreateWindow("", SDL_WINDOWPOS_CENTERED,
    SDL_WINDOWPOS_CENTERED, screenW, screenH, windowFlags);


and then, *IF* the user has configured it in fullscreen mode in its .ini, it tries to go fullscreen with the desktop mode:

SDL_SetWindowFullscreen(video.window, SDL_WINDOW_FULLSCREEN_DESKTOP);


This sequence of operations is currently failing because SDL_SetDisplayModeForDisplay() in SDL_video.c fails because display->desktop_mode is not being initialized with its correct value: SetDisplayMode() in SDL_kmsdrmvideo.c will not be able to set the mode because it detects the mode to have a driverdata of 0x0 ("if (!modedata)") and rightfully returns an error.

So, the included patch fixes this small problem, and programs that first change the video mode and then try to go fullscreen with the system video mode will now work.
The patch simply fixes an small omission, but its really needed now that dynamic video mode changing was implemented on the KMSDRM backend.
