Now it returns an array and optional count, to match other SDL3 APIs.
SDL_GetTouchName() was replaced with a function that takes an instance ID
instead of an index, too.
This uses the same `SDL_VerbNoun` format as the rest of SDL3, and also
adds stronger effort to invalidate cached state in the backend, so cooperation
improves with apps that are using lowlevel rendering APIs directly.
Fixes#367.
This gives applications and binding systems a clearer view of what the hardware is so they can make intelligent decisions about how to present things to the user.
Gamepad mappings continue to use abxy for the face buttons for simplicity and compatibility with earlier versions of SDL, however the "SDL_GAMECONTROLLER_USE_BUTTON_LABELS" hint no longer has any effect.

Almost nothing checks these return values, and there's no reason a valid
lock should fail to operate. The cases where a lock isn't valid (it's a
bogus pointer, it was previously destroyed, a thread is unlocking a lock it
doesn't own, etc) are undefined behavior and always were, and should be
treated as an application bug.
Reference Issue #8096.
The following objects now have properties that can be user modified:
* SDL_AudioStream
* SDL_Gamepad
* SDL_Joystick
* SDL_RWops
* SDL_Renderer
* SDL_Sensor
* SDL_Surface
* SDL_Texture
* SDL_Window
This is meant to offer a simplified API for people that are either migrating
directly from SDL2 with minimal effort or just want to make noise without
any of the fancy new API features.
Users of this API can just deal with a single SDL_AudioStream as their only
object/handle into the audio subsystem.
They are still allowed to open multiple devices (or open the same device
multiple times), but cannot change stream bindings on logical devices opened
through this function.
Destroying the single audio stream will also close the logical device behind
the scenes.
The sequence order of the four paddles is not obvious, with SDL and Xbox
controllers swapping the order of P2 and P3 relative to each other.
If we group them into left and right, then it becomes more obvious.

The current status is stored in the SDL_rwops 'status' field to be able to determine whether a 0 return value is caused by end of file, an error, or a non-blocking source not being ready.
The functions to read sized datatypes now return SDL_bool so you can detect read errors.

This rips up the entire SDL audio subsystem! While we still feed the audio device from a separate thread, the audio callback into the app is now gone a totally optional alternative.
Now the app will bind an SDL_AudioStream to a given device and feed data to it. As many streams as one likes can be bound to a device; SDL will mix them all into a single buffer and feed the device from there.
So not only does this function as a basic mixer, it also means that multiple device opens are handled seamlessly (so if you want to open the device for your game, but you also link to a library that provides VoIP and it wants to open the device separately, you don't have to worry about stepping on each other, or that the OS will fail to allow multiple opens of the same device, etc).

Render targets are a core feature of SDL 3.0, so this flag has been removed.
The OpenGL ES renderer still doesn't support them, but we'll deal with that later.
