This simplifies the API and removes a level of API translation between the int variants of the functions and the float implementation

Also cleaned up logic for whether we need to poll for events:
- We need to periodically poll for joysticks to handle hotplug.
- We need to frequently poll for joysticks and sensors when they're open so their state can be updated
This function is useful for accumulating relative mouse motion if you want to only handle whole pixel movement.
e.g.
static float dx_frac, dy_frac;
float dx, dy;
/* Accumulate new motion with previous sub-pixel motion */
dx = event.motion.xrel + dx_frac;
dy = event.motion.yrel + dy_frac;
/* Split the integral and fractional motion, dx and dy will contain whole pixel deltas */
dx_frac = SDL_modff(dx, &dx);
dy_frac = SDL_modff(dy, &dy);
if (dx != 0.0f || dy != 0.0f) {
...
}
Feedback from @icculus:
"IsTablet" uses "is" as a form of "to be" ...like, the actual question is of its nature.
The rest is just a superfluous word in the question and it flows as better English with if (RectEmpty) than if (IsRectEmpty)

`SDL_QUERY`, `SDL_IGNORE`, `SDL_ENABLE`, and `SDL_DISABLE` have been removed.
SDL_EventState() has been replaced with SDL_SetEventEnabled()
SDL_GetEventState() has been replaced with SDL_EventEnabled()
SDL_GameControllerEventState has been replaced with SDL_SetGamepadEventsEnabled() and SDL_GamepadEventsEnabled()
SDL_JoystickEventState has been replaced with SDL_SetJoystickEventsEnabled() and SDL_JoystickEventsEnabled()
SDL_ShowCursor() has been split into three functions: SDL_ShowCursor(), SDL_HideCursor(), and SDL_CursorVisible()
Fixes https://github.com/libsdl-org/SDL/issues/6929
Instead of indexing into an internal list of devices which requires locking, we return a list of device IDs which can then be queried individually.

Make PS2/PSP use the mainFunction argument for SDL_RunApp().
Make PSP SDL_RunApp() return the value from mainFunction().
Make PS2 SDL_RunApp() call SDL_SetMainReady() like all other
SDL_RunApp() functions. (It doesn't affect anything for PS2 as
SDL_MAIN_NEEDED isn't defined.)
