These were added a very long time ago and seem to serve no purpose now, as the functionality they provided is now in core Wayland protocols, current information on their usage and status is nonexistent, no modern compositor seems to support them, and the code paths are untested and subject to bit-rot at this point. It also causes duplicate symbol issues when statically linking an application to both Qt and SDL.
Emscripten was using its own, private integer in order to allocate
new SDL_JoystickIDs. SDL keeps a similar integer for allocating
joystick-ids, one which is shared across multiple joystick backends.
SDL 2.0.13 introduces a new joystick-backend, a Virtual joystick
backend, which allows for software-driven joysticks, and which is
designed to sit alongside joystick-backends that provide access to
physical joysticks.
The Emscripten and the Virtual backends were, at times, getting
allocated the same SDL_JoystickIDs, if and when both backends were used
simultaneously. This could happen if, for example, an application
was using a virtual joystick in order to drive a touch-screen
based joystick, while also supporting physical joysticks through the
Emscripten backend.
When two joysticks end up with the same SDL_JoystickID, conflicts
can occur. For example, disconnecting a physical joystick with
the same SDL_JoystickID as a virtual one, can lead to the virtual
joystick being closed, inadvertently.
This fix makes the Emscripten backend use SDL's cross-joystick-backend
integer counter, which is shared among joystick backends, for allocating
new SDL_JoystickIDs, rather than a private, Emscripten-specific
counter.

If the done signal is emitted by the common event handler, the window and all of its children have already been destroyed, so don't try to render with invalid renderer objects.
This fixes a warning that could show up on some MS linkers which use a
slightly different warning message than expected.
Amends check_linker_supports_version_file to include the "unrecognized
option" warning message.
When converting normalized coordinates to pixel coordinates, the valid range is 0 to (width or height) - 1, and the pixel coordinate of width or height is past the edge of the window.

I've added an additional patch that expands on the same basic idea as the first one; it makes SDLInputConnection and DummyEdit into public classes so that they can be overridden from the Xamarin end if their functionality needs to be extended. (In my case, I need to change the type of software keyboard that's displayed.)

XINPUT_STATE_EX isn't actually a thing, we can just use the normal XINPUT_STATE

(cherry picked from commit e8f4045d0bccacbf8f4b716d0dde17140e9f2cc4)
This patch adds a new createSDLMainRunnable() method to SDLActivity.
Currently, SDL on Android expects to find SDL_main somewhere in native code. When using SDL in a Xamarin application, however, what we really want to do is write our entrypoint in managed code. The easiest way to do this is to allow subclasses of SDLActivity to provide their own Runnable to the SDL thread, as in the attached patch.
