Markus Volk 70b4278eab libsdl2: update 2.0.22 -> 2.24.0

In addition to lots of bug fixes, here are the major changes in this release:

General:

New version numbering scheme, similar to GLib and Flatpak.
An even number in the minor version (second component) indicates a production-ready stable release such as 2.24.0, which would have been 2.0.24 under the old system.
The patchlevel (micro version, third component) indicates a bugfix-only update: for example, 2.24.1 would be a bugfix-only release to fix bugs in 2.24.0, without adding new features.
An odd number in the minor version indicates a prerelease such as 2.23.0. Stable distributions should not use these prereleases.
The patchlevel indicates successive prereleases, for example 2.23.1 and 2.23.2 would be prereleases during development of the SDL 2.24.0 stable release.
Added SDL_GetPointDisplayIndex() and SDL_GetRectDisplayIndex() to get the display associated with a point and rectangle in screen space
Added SDL_bsearch(), SDL_crc16(), and SDL_utf8strnlen() to the stdlib routines
Added SDL_CPUPauseInstruction() as a macro in SDL_atomic.h
Added SDL_size_mul_overflow() and SDL_size_add_overflow() for better size overflow protection

Added SDL_JoystickAttachVirtualEx() for extended virtual controller support
Added joystick event SDL_JOYBATTERYUPDATED for when battery status changes
Added SDL_GUIDToString() and SDL_GUIDFromString() to convert between SDL GUID and string
Added SDL_HasLSX() and SDL_HasLASX() to detect LoongArch SIMD support
Added SDL_GetOriginalMemoryFunctions()
Added SDL_GetDefaultAudioInfo() to get the name and format of the default audio device, currently implemented for PipeWire, PulseAudio, WASAPI, and DirectSound
Added HIDAPI driver for the NVIDIA SHIELD controller (2017 model) to enable support for battery status and rumble
Added support for opening audio devices with 3 or 5 channels (2.1, 4.1). All channel counts from Mono to 7.1 are now supported.
Rewrote audio channel converters used by SDL_AudioCVT, based on the channel matrix coefficients used as the default for FAudio voices
SDL log messages are no longer limited to 4K and can be any length
Fixed a long-standing calling convention issue with dynapi affecting OpenWatcom or OS/2 builds
Windows:

Added initial support for building for Windows and Xbox with Microsoft's Game Development Kit (GDK), see docs/README-gdk.md for details
Added a D3D12 renderer implementation and SDL_RenderGetD3D12Device() to retrieve the D3D12 device associated with it
Added the hint SDL_HINT_WINDOWS_DPI_AWARENESS to set whether the application is DPI-aware. This hint must be set before initializing the video subsystem
Added the hint SDL_HINT_WINDOWS_DPI_SCALING to control whether the SDL coordinates are in DPI-scaled points or pixels
Added the hint SDL_HINT_DIRECTINPUT_ENABLED to control whether the DirectInput driver should be used
Added support for SDL_GetAudioDeviceSpec to the DirectSound backend
Linux:

Support for XVidMode has been removed, mode changes are only supported using the XRandR extension
Added the hint SDL_HINT_VIDEO_WAYLAND_MODE_EMULATION to control whether to expose a set of emulated modes in addition to the native resolution modes available on Wayland
Added the hint SDL_HINT_KMSDRM_DEVICE_INDEX to specify which KMSDRM device to use if the default is not desired
Added the hint SDL_HINT_LINUX_DIGITAL_HATS to control whether to treat hats as digital rather than checking to see if they may be analog
Added the hint SDL_HINT_LINUX_HAT_DEADZONES to control whether to use deadzones on analog hats
macOS:

Bumped minimum OS deployment version to macOS 10.9
Added SDL_GL_FLOATBUFFERS to allow Cocoa GL contexts to use EDR
Added the hint SDL_HINT_MAC_OPENGL_ASYNC_DISPATCH to control whether dispatching OpenGL context updates should block the dispatching thread until the main thread finishes processing. This hint defaults to blocking, which is the safer option on modern macOS.

Poky

Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.

Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.

As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.

The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/

OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Contribution Guidelines

The project works using a mailing list patch submission process. Patches should be sent to the mailing list for the repository the components originate from (see below). Throughout the Yocto Project, the README files in the component in question should detail where to send patches, who the maintainers are and where bugs should be reported.

A guide to submitting patches to OpenEmbedded is available at:

https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded

There is good documentation on how to write/format patches at:

https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines

Where to Send Patches

As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:

OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):

Git repository: https://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org

BitBake (files in bitbake/):

Git repository: https://git.openembedded.org/bitbake/
Mailing list: bitbake-devel@lists.openembedded.org

Documentation (files in documentation/):

Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
Mailing list: docs@lists.yoctoproject.org

meta-yocto (files in meta-poky/, meta-yocto-bsp/):

Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
Mailing list: poky@lists.yoctoproject.org

If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
