Add `str_utf8_offset_bytes_to_chars` and `str_utf8_offset_chars_to_bytes` functions to base system to convert between byte and UTF-8 character offsets in UTF-8 strings.
Previously, this was separately implemented in the textrender and in the lineinput helper.
These textrender functions are entirely replaced by the new functions:
- `ITextRender::SelectionToUTF8OffSets` (by `str_utf8_offset_chars_to_bytes`)
- `ITextRender::UTF8OffToDecodedOff` (by `str_utf8_offset_bytes_to_chars`)
- `ITextRender::DecodedOffToUTF8Off` (by `str_utf8_offset_chars_to_bytes`)
These lineinput helper functions are reimplemented using the new functions:
- `CLineInput::OffsetFromActualToDisplay` (uses `str_utf8_offset_bytes_to_chars`)
- `CLineInput::OffsetFromDisplayToActual` (uses `str_utf8_offset_chars_to_bytes`)
Register the `OnWindowResize` listener in the engine client instead of the game client and properly dispatch the event also to the editor, so text containers in the editor are cleared when the window is resized.
Closes#7018.
Fix text containers rendering broken text after the language is changed, as this cleared the glyph atlas without clearing the references to the glyph positions in the text containers. Now `OnWindowResize` is also called on language change to reset all text containers.
However, the glyph atlas is not cleared on normal window resize anymore, because this seems to be unnecessary.
Replace skyline-based texture atlas algorithm with a rectangle packing algorithm that tracks empty atlas sections using `std::vector`s. The algorithm is very loosely inspired by https://github.com/TeamHypersomnia/rectpack2D.
Increases texture atlas utilization from ~70% to ~90-94%, i.e. less space in the atlas is unused.
Decreases the computational time to find suitable free regions in the atlas by factor 40x-164x (depending on atlas dimension and utilization). In absolute numbers, the computational time necessary for a glyph being added to the atlas is decreased from 0.0556ms-0.4679ms to 0.0013ms-0.0051ms (depending on atlas dimension and utilization).
The memory usage for the texture atlas algorithm increases from a maximum of ~128 KB to a maximum of ~3 MB.
This still works
$ ./DDNet "connect 127.0.0.1"
But now also this works

Add `fonts/index.json` which specifies:
- List of all font files that should be loaded (filenames).
- Default font (specified by family name or by family and style name).
- Font variants for different languages, using the name of the language file as key.
- Fallback fonts.
- Icon font.
There are characters (e.g. all in `刃直海角骨入`) that look different depending on the language of the content being Japanese, Simplified Chinese, Traditional Chinese and Hangul, because Unicode uses the same codepoint for characters regardless of the language. To render these characters correctly, the active variant font is switched depending on the selected language.
The `ITextRender` interface is changed so the current language variant can be set using `SetFontLanguageVariant` and the default and icon fonts can be toggled using `SetFontPreset`. The class `CFont` is removed entirely.
The text render is restructured: The font faces and font atlas are now managed by a separate class `CGlyphMap` like on upstream. As the text fill and outline textures always have the same size, the texture skyline only needs to be stored once and free positions in the atlas only need to be calculated once for each glyph instead of separately for the fill and outline textures.
The font files and their licenses are also updated:
- Update Source Han Sans to version 2.001.
- Update Glow Sans Japanese Compressed to version 0.93.
- Update Deja Vu Sans to version 2.37.
- Update Font Awesome icons font to March 2023 version.
Closes#6881.
Rectangles with inverted round corners (`IGraphics::CORNER_I*`) are currently not used anywhere and also only supported when using `Draw4`.
They also feel clunky to use due to the inverted corners being drawn outside of the specified rectangle area.
`stdout_output_level` for printing to stdout, `console_output_level` for
printing to local console and remote console and `loglevel` for the log
file.
Keep the old log level filters 0 for info and more severe, 1 for debug
and more severe and 2 for trace and more severe, introducing -1 for
warn, and -2 for error. -3 will show no log messages at all.
When memory for a command or data in the command buffer cannot be allocated in `CGraphics_Threaded::AddCmd` and `CGraphics_Threaded::AllocCommandBufferData` the command buffer is cleared so it should always be possible to allocated memory successfully on the second try. Therefore assertions are added and the return values and inconsistent checks of the functions are removed.
The usage of `AddCmd` is simplified by automatically deriving an error message based on the type of the template parameter.
Only add assertion to prevent empty filename, as this causes Valgrind to crash.
Handle empty filename used for special null-image separately in gameclient.
When starting with `dbg_stress 1` the invalid texture was never actually getting loaded, which was causing the client to crash when using the Vulkan backend and starting with `dbg_stress 1`.
Additionally ensure that the invalid texture is 16x16 pixels large and loaded with the texture flags to support usage for tile rendering.
Closes#6504.
Show a short message below the existing chat mentions message that is shown in the top left area of the editor above the layers/images/sounds button when the player character is moved ingame while the editor is open. The messages are cleared when the editor is activated and when the client is disconnected.
Closes#1993.

6790: Prevent /swap with paused players r=def- a=Robyt3
Prevent swapping if either of the players is paused (i.e. their character is not in the gameworld), as this can cause them to be stuck in midair after swapping, which can be exploited to skip parts.

6793: Use `std::vector` and `std::deque` instead of most `std::list`s r=def- a=Robyt3
Use `std::vector` in cases where elements are only inserted at the end of the collection.
Use `std::deque` in cases where elements are only inserted/deleted at the beginning/end of the collection.
Use `std::list` in the remaining single case where elements are being removed from arbitrary positions and added at either the beginning or the end of the collection.
Adjust variables names. Don't use separate prefix for `std::deque`s and `std::list`s, as they are only used very rarely. Closes#6779.
