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.

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
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.
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.
Use icons for all server settings buttons. Rearrange and group buttons.
Show buttons in disabled state when they are not useable instead of hiding them.
Remove checker background from server settings list.
Overhaul hotkeys, also show hotkeys in the tooltips:
- Enter: add command
- Alt+Enter: update command (previously M)
- Alt+Up/Down: move command up/down (previously no hotkey)
- Delete: delete command
Don't activate command lineinput when selecting, moving or deleting elements, as this prevents the listbox from accepting the delete hotkey.
Fix server settings listbox being active while file dialog is open.
Ensure extra editor dragbar area matches the respective toolbar size.
Remove spacing on the left side of extra editors to improve alignment.
Increase status bar button sizes and make them consistent.
Use `enum` to track active extra editor instead of using multiple `bool`s.
Disable extra editor buttons when tile picker is shown, as the extra editors are not rendered in this case.
Port the `CJsonWriter` utility class from upstream, which makes outputting correct JSON easier.
Add `CJsonWriter` as an abstract class that can write to different outputs. Two implementations `CJsonFileWriter` (writes to a file) and `CJsonStringWriter` (writes to an `std::string`) are added. Upstream `CJsonWriter` can only write to files.
The same tests are added for both implementations. Duplicate code is avoided by using typed tests with two separate test fixtures.
`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.
Port map and editor support for `CURVETYPE_BEZIER` from upstream, i.e. support bezier curves with configurable in- and out-tangents for every envelope point.
The in- and out-tangents are represented by triangles and can be dragged in the envelope editor like the envelope points.
Support reading and writing the bezier information as a separate UUID-based map item. If the bezier information is not found, bezier will default to linear behavior. Old clients will still be able to read the new maps and ignore the unknown map item. The unknown curvetype will also be handled as linear by old clients.
Allow reading upstream maps that use `CMapItemEnvelope` version 3. On upstream, a different struct is used to store all envelope points including bezier information, which broke compatibility to old clients.
Fix holding Ctrl for slow envelope point editing not working for vertical movement.
Highlight the currently selected element (envelope point or bezier tangent marker) which is being used with the value/time edit boxes.
Hide the value/time edit boxes when no element is selected.
Previously it reported the internal file data size (compressed). This
made the `map_resave` tool do the wrong job.

To reduce duplicate code and to add validation for tile skip everywhere.
Add separate `CMapItemLayerTilemap::TILE_SKIP_MIN_VERSION` constant and change `CMapItemVersion::CURRENT_VERSION` back to the previous version, as maps with tile skip can be loaded but skip is not used when saving.
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.
When multiple files or folder have the same name in multiple storage locations, only pass the first entry (file or folder, whichever comes first) to the callback. To prevent files with the same name form being listed multiple times, e.g. in the demo browser, editor file browser, and asset lists.

Decrease size of layer and point popups that previously had color properties which need less space now.
Support shift-rightclicking color picker buttons to copy the color to the clipboard in RRGGBBAA hex format.

Compressing the data with zlib takes the majority of the time when saving a datafile. Therefore, compressing is now delayed until the `CDataFileWriter::Finish` function is called. This function is then off-loaded to another thread to make saving maps in the editor not block the rendering.
A message "Saving…" is shown in the bottom right of the editor view while a job to save a map is running in the background.
While a map is being finished in a background thread another save for the same filename cannot be initiated to prevent multiples accesses to the same file.
Closes#6762.
A copy of the map currently open in the editor is saved every 10 minutes to the `maps/auto` folder (interval configurable, see below). The automatically saved map uses the filename of the original map with an additional timestamp. Per map name 10 autosaves are kept in the `auto` folder before old autosaves will be deleted (number configurable, see below).
Add config variable `ed_autosave_interval` (0 - 240, default 10) to configure the interval in minutes at which a copy of the current editor map is automatically saved to the 'auto' folder.
Add config variable `ed_autosave_max` (0 - 1000, default 10) to configure the maximum number of autosaves that are kept per map name (0 = no limit).
Autosaving will not take place in the 5 seconds immediately after the map was last modified by the user, to avoid interrupting the user with the autosave.
This will only delay autosaving for up to 1 minute though, so autosaves are not prevented entirely, should the user continuously edit the map.
When the editor is reopened after being closed for more than 10 seconds, the autosave timer will be adjusted to compensate for the time that was not spent on editing in the editor.
When the map is saved manually by the user the autosave file is also updated, if it's outdated by at least half of the configured autosave interval. This ensures that autosaves are always available as a periodic backup of the map.
When a copy of the current map is saved, this does not update the autosave and will also no longer reset the modified state. The modified state should reflect whether changes have been made that are not saved to the current map file. As saving a copy does not update the current file, the modified state should not be reset in this case.
Closes#6693.

Minimum SDL version 2.0.16 is required for `SDL_FlashWindow`. The SDL version schema changes after version 2.0.22 to 2.24.0 etc. (minor version is used instead of patchlevel) which was causing the condition that checks for minimum version 2.0.16 to not work correctly with newer SDL versions.

6665: Fix ordering of unfinished/unconnected tees r=heinrich5991 a=Learath2
<!-- What is the motivation for the changes of this pull request? -->
I thought there was initially a strict weak ordering issue here but upon further inspection noticed it's fine.
However, people with negative score were getting sorted undeterministically, basically every unfinished tee was treated as equal since `!comp(a, b) && !comp(b, a)`. Sorting them by name was the intention.
I also got rid of the old `INT_MIN` "hack", it was only there to make the code shorter and it's no longer possible with the newly flipped sign without flipping it back on the client which is ugly.
Also made `ScoreKind` `const`, not sure if any compiler optimizes on that but why not? If we ever move to C++20 this could be a generic lambda instead where we can template `ScoreKind` and make sure it gets optimized properly.
Tidbit: I treated score 0 as a normal score, I'm not sure what it implies.

6673: Clear Victim Team render info on skin changes r=Robyt3 a=Jupeyy
fixes#6662
This should fix the issue, I guess, by simply clearing the render info. I can't find an easy way to restore the original skins of the team members as we don't save their IDs.
I couldn't directly trigger the assert, but I could certainly see the skin getting invalid when killen the team and switch to "vanilla only skins". (Edit: When triggering it a few times I got the assert)
The code generally looks a bit hacky. Maybe the original author can refactor it a bit

Separate friends list into three groups, which can be expanded and collapsed: online players, online clanmates and offline friends.
Friends with the same name/clan are no longer grouped together. Instead, each individual player that is online and has name/clan matching a friend is shown in either the online players or online clanmates group. Friends for which no matching players are found are shown in the offline group.
Friends in the friend list can no longer be selected. Instead, left-clicking a friend selects the server that the friend is on. Double-clicking a friend joins the server that they are playing on.
Render small X button in top-right corner of every friend list entry to remove the respective friend instead of using one button that removes the selected friend.
Change "Add Friend" button to "Add Clan" when only clan is entered.
Remove excess empty space from layout.
