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.
The `Translate` function modifies the first argument, so the client ID keeps changing when the function is being used in a loop. Additionally, calling `Translate` manually is not necessary for messages, as client IDs in messages are already automatically translated when using `SendPackMsg`. Both faults can cause emoticons to appear on the wrong players when the emote spamprotection limits emotes to nearby players.
This still works
$ ./DDNet "connect 127.0.0.1"
But now also this works
$ ./DDNet "connect tw-0.6+udp://ger10.ddnet.org:8303"

When quitting or restarting the client, clear the screen and render a message "Quitting. Please wait…" or "Restarting. Please wait…" respectively.
Previously the last frame would keep getting shown while the client is busy with cleanup tasks. Rendering a final message before the client window stops being updated provides a cleaner user experience.
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.
`shared_ptr`s of `CServer::m_pDnsblLookup[ClientID]` are set, but not
cleaned up when done. Therefore the Job is kept alive until the player
disconnects and a new player joins on that slot. Currently this means
that the full linked list of jobs is kept alive.
When the Job is overwritten with a new job, all the remaining objects in
the list can be dropped. With enough jobs, that is causing a stack
overflow in the destructor.
This patch fixes this overflow by making the lifetime independent of the
previous Job. Jobs can get dropped after processing them, even when the
previous job is still alive.
Fixes#6954
Simplify memory management of groups, layers, images, sounds and envelopes by using `std::shared_ptr` for all of them.
Clear brush when creating a new map to prevent crash due to unloaded textures being used in tile layer. Closes#6935.
Also fix crash when restoring a saved brush after removing an image that is being used by it.
Switch to using the Windows-specific `HANDLE` and Windows API functions instead of `FILE *` and standard library functions in all Windows IO function implementations.
Using `CreateFileW` instead of `_wfsopen` to open files is necessary, as only `CreateFileW` allows specifying all necessary sharing flags. The sharing flags `FILE_SHARE_READ` and `FILE_SHARE_WRITE` were previously already specified by using `_SH_DENYNO` with `_wfsopen`, but `FILE_SHARE_DELETE` can only be set when using `CreateFileW`. The flags are necessary so files which are in use by the game can still be opened by other processes. In particular, `FILE_SHARE_DELETE` allows deleting/renaming of open files, which was previously not possible. This was causing the smart editor saving process that renames files to fail if a map file is currently in use.
Because `CreateFileW` returns a `HANDLE` instead of a `FILE *` we have to use the `HANDLE`-based Windows IO functions everywhere.

The old code looked pretty weird. It checked for `CFGFLAG_SERVER |
CFGFLAG_GAME` being set above, and then used the passed-in parameter to
find the command. I think it'd be better to just look for `CFGFLAG_GAME`
and then find the command using `CFGFLAG_GAME`.

Check if datafile data cannot be read entirely (according to the data size specified in the header) and check for decompression errors. In case of errors, let `GetData` return `nullptr` and `GetDataSize` return `0` for the respective index.
Internally the decompressed size is set to `-1` for data which failed to load, so loading of those data will not be attempted again because it would only fail again and can cause additional log messages.
