Using Wii U GameCube USB adapter with multiple controllers attached and
restarting SDL input in a game results in extra joysticks with NULL name.
HIDAPI_CleanupDeviceDriver() shut down joysticks by iterating through
device->num_joysticks but each HIDAPI_JoystickDisconnected() decreases
device->num_joysticks and shifts joysticks array down. Resulting in only
half of controllers being shutdown. It worked with only 1 controller
attached though.
Disconnect HIDAPI device joystick 0 until there are none left.
Message in the log, when going to background:
"call to OpenGL ES API with no current context (logged once per thread)"
Because of SDL_WINDOWEVENT_MINIMIZED is sent from the Java Activity thread.
It calls SDL_RendererEventWatch(), _WindowEvent() and glFinish() without context.
Solution is to move sending of SDL_WINDOWEVENT_MINIMIZED to the SDL thread.
Added the functions SDL_JoystickFromPlayerIndex(), SDL_JoystickSetPlayerIndex(), SDL_GameControllerFromPlayerIndex(), and SDL_GameControllerSetPlayerIndex()
For some obscure reason, the order in which the libdrm/libgbm libraries
are loaded matters.
Without this fix, the first call to check_modesetting() will work and
load then unload all symbols properly, but the second call to this
function will lock up as soon as dlopen() is called on libdrm.
Swapping the order in which the libdrm and libgbm libraries are loaded
is enough to fix (or work around?) this issue.

I realized I made a minor mistake in my patch: I changed the constructor prototype for SDL_DisplayData, but didn't update the declaration in the .h file. The compiler and linker don't complain, but it would probably be best to fix in case a later change runs into a problem from the mismatch. I have attached a patch to fix this.

On a Dualshock 4 controller using hidapi driver, calling SDL_JoystickRumble with a duration too long (SDL_HAPTIC_INFINITY for example) causes the rumble to stop immediately.
This happens because of integer overflow on line 301 of SDL_hidapi_ps4.c
(https://hg.libsdl.org/SDL/file/a3077169ad23/src/joystick/hidapi/SDL_hidapi_ps4.c#l301), which sets expiration time in the past.
When we initialize the controller it has an internal rumble sequence number, and if our rumble sequence number doesn't match that, rumble won't happen. To fix that we cycle through the range of sequence numbers, and at some point we'll match up with the controller's sequence number and it'll roll forward until it matches our next rumble sequence number.

There appears to be no way to directly access the display DPI on iOS, so as an approximation the DPI for the iPhone 1 is used as a base value and is multiplied by the screen's scale. This should at least give a ballpark number for the various screen scales. (based on https://stackoverflow.com/questions/25756087/detecting-iphone-6-6-screen-sizes-in-point-values it appears that both 2x and 3x are used)
I have updated the patch to use a table of current devices and use a computation as a fallback. I have also updated the fallback computation to be more accurate.
