To convert between UTF-8 encoded strings and wide character strings used with the Windows API.
The functions use `std::wstring` and `std::string`, to simplify the usage and support arguments with arbitrary length.
Also add some tests for the functions.
Port the line input (UI edit boxes, chat, console) and Input Method Editor (IME) support from upstream. Closes#4397.
General
------------------------------
Fix issues with the text input. Closes#4346. Closes#4524.
Word skipping (when holding Ctrl) is overhauled to be consistent with the Windows / Firefox experience that I took as reference.
Improve usability by not blinking (i.e. always rendering) the caret shortly after is has been moved.
UI text input
------------------------------
Fix inconsistent mouse-based left and right scrolling (closes#4347).
Support smooth left and right scrolling.
Chat
------------------------------
Support keyboard-based text selection of the chat input.
Mouse-based selection could be support in the future when we decide to add something like an ingame UI cursor.
Support smooth up and down scrolling of the chat input, removing the old hack that offsets the input string to simulate scrolling.
Console
------------------------------
Also support mouse-based text selection of the command input.
Only text from either the command input or the console log can be selected at the same time. This ensures that Ctrl+C will always copy the text that is currently visually selected in the console.
Check for Ctrl+C input event in event handler instead of in render function, to hopefully fix the issue that copying does not work sometimes (closes#5974 until further notice).
When Ctrl+C is used to copy text from the console log, the selection is cleared. This should make it more clear when text was copied from the log.
Fix an issue that was preventing the console log selection from being cleared, when all log lines are selected.
Remove Ctrl+A/E hotkeys that move cursor to beginning/end respectively. Ctrl+A now selectes all text like for all other inputs. Home and End keys can still be used to go the beginning and end.
Remove Ctrl+U/K hotkeys that clear everything before/after the cursor respectively. Hold shift and use Home/End to select everything instead.
IME support
------------------------------
Render list of IME candidates in the client on Windows, so the candidate list can also be viewed in fullscreen mode. There is no API available to retrieve a candidate list on the other operating systems.
Improve composition rendering by underlining the composition text instead of putting it in square brackets.
Track active input globally to properly activate and deactivate IME through the SDL functions.
Closes#1030. Closes#1008.
Password rendering
------------------------------
Fix rendering of passwords containing unicode. Instead of rendering one star character for each UTF-8 `char`, render on star for every unicode codepoint.
Show the composition text also for passwords. Without seeing the composition text it's hard to type a password containing those characters. The candidate window exposes the composition anyway. If you don't want to expose your password this way, e.g. while streaming, you could:
1. Use a latin password and switch off the IME for the password input with the IME hotkey.
2. Blank your screen with an external program while you are streaming and entering passwords.
3. Use binds to authenticate in rcon or to set the server browser password.
Refactoring
------------------------------
Move all text input logic and general rendering to `CLineInput`.
A `CLineInput` is associated with a particular `char` buffer given as a pointer either in the constructor or with `SetBuffer`. The maximum byte size of the buffer must also be specified. The maximum length in unicode codepoints can also be specified separately (e.g. on upstream, name are limited by the number of unicode codepoints instead).
Add `CLineInputBuffered`, which is a `CLineInput` that own a `char` buffer of a fixed size, which is specified as a template argument. As `CLineInput` does not own a buffer anymore, this reduces duplicate code for line inputs that need their own buffer.
Add `CLineInputNumber` which has additional convenience functions to consider the text as an `int` or `float`, to reduce duplicate code in those cases. In the future we could also add an input filter function so that only numbers can be entered in the number input.
Add `CLineInput::SetClipboardLineCallback` to handle the case that multiple lines of text are pasted into a lineinput. This reduces duplicate code, as this behavior was previously implemented separately for chat and console. The behavior is also fixed to be consistent with the console on Windows, so the first line being pasted edits the current input text and then sends it instead of being sent on its own without the existing input text.
Add `CalcFontSizeAndBoundingBox` to UI to reduce duplicate code. Expose `CalcAlignedCursorPos` as static member function to reuse it for line input.
Dispatch input events to UI inputs through the event handler instead of storing them in a duplicate buffer.
Use `size_t` for line input cursor position, length etc. and for `str_utf8_stats`.
Add `IButtonColorFunction` to UI to describe a functions that defines colors for the Default, Active and Hovered states of UI elements. Add some default button color functions. Use button color function to reduce duplicate code in scrollbar rendering.
Use `vec2` instead of two `floats` to represent the mouse positions in the text renderer.
Remove `CaretPosition` again, as it does not calculate the correct Y position near line breaks due to the wrapping being different when not rendering the entire string. Instead, calculate the exact caret position when rending a text container and store the caret position in the text cursor for later use.
IME usage guide (Windows)
------------------------------
1. Install the respective language and the Microsoft-IME keyboard (e.g. for Chinese, Japanese or Korean).
2. Launch the game (or a text editor to first try out the IME). Note that Windows may track the input language separately for every application. You can change this in the Windows input settings so the input language is changed globally.
2. Switch the input language using the hotkey Windows+Space or another hotkey that you configured in the Windows input settings (Alt+Shift is the default, but you should consider disabling it, to avoid accidentally changing the input language while playing).
3. Switch from Latin/English input mode to the respective asian input mode.
- Chinese: Use Ctrl+Space to switch between English and Chinese input mode. You can change this hotkey in the IME's settings.
- Japanese: Use Ctrl+Space to switch between Alphanumeric and Hiragana/Katakana input mode. You can change this hotkey in the IME's settings.
- Korean: Use Right Alt to switch between English and Hangul input mode. You cannot change this hotkey as of yet.
- Note that the input mode is also tracked per application, but there is no setting to change this behavior as far as I know, so you'll need to switch for every application separately.
4. Start typing. The underlined text is the current composition text. While a composition is active, you can only edit the composition text. Confirm the composition with Space or by selecting a candidate from the candidate list with the arrow keys. Cancel the composition with Escape or by using Backspace to delete the composition text. Note that not all languages offer a candidate list.
SDL version-specific issues
------------------------------
- 2.26.5, 2.24.2, 2.0.22: IME candidates work. But there are minor bugs when moving the composition cursor.
- 2.0.18, 2.0.20: IME candidates work.
- 2.0.16 (our current version): IME candidates cannot be determined with Windows API. Windows tries to draw the composition window like before, so this does not work in fullscreen mode.
- 2.0.8 (upstream 0.7): IME candidates work. But this SDL version is too old for us.

Reduces duplicate code. This also ensures that the log messages are properly zero-terminated and that they do not end with truncated unicode characters.
So the string formatting can be reused in other places. Passing variadic arguments directly to another function is not possible.
The function must have a different name, as overloading `str_format` would cause the wrong function to be called when passing the `va_list`. The same naming with suffix `_v` is used for the logging functions.
Add `random_float(float min, float max)` to generate a random `float` between `min` and `max`.
Add `random_float(float max)` to generate a random `float` between `0.0f` and `max`.
Replace existing `RandomDir` with this function. This function was biased towards the corners, as it first generates a random `vec2` with `x` and `y` in `[-0.5f;0.5f]` and then normalizes it, which doesn't result in a uniform distribution of directions. Now the random direction is generated by taking a random angle and then converting it to a direction which is per definition already normalized.
To generate a random angle in the range `[0.0f;2.0f * pi[`. This ensures that the random angle cannot be `2.0f * pi`, which would be identical to the angle `0.0f` and therefore cause the random angle to be less uniformly selected.
Note that this first casts `RAND_MAX` to a `float` and then uses `std::nextafter` to get the next larger `float`. Using `RAND_MAX + 1` would cause an integer overflow on systems where `RAND_MAX == INT_MAX` (e.g. Ubuntu and macOS).
6324: Optimize client ids map update r=def- a=0xfaulty
I have launched support for 128 players in testing mode on my server, it's means it's time for another step in this direction here. Perhaps not all changes will be clear, I am ready to answer/discuss them as usual. Let me know if I forgot or didn't take anything into account.

6345: Set constant and uniform names for the server and client CMake targets r=def- a=Kaffeine
This MR set the server and client CMake target names to `game-server` and `game-client` which are uniform with other targets such as `engine-gfx`, `engine-shared`, and `game-shared`.
Set uniform names for the targets to:
1. Avoid long rebuilds on the target _executable_ name changed
2. Provide the same name for different executables and/or different setup (use-cases are `cmake --build . --target game-server` and various CMake target lookups in IDEs)
Those changes are necessary but not enough to allow CI for custom app name on all platforms.
Personally this 'll allow me switch to between DDNet and Infclass branches faster and without breaking the targets configuration (e.g. with that patchset I can have `game-client` as an active target in both branches), and also reduces the conflicts in `CMakeLists.txt`.
Easier to switch between the forks => easier to contribute.

Replacing the C standard headers with the C++ standard headers causes various `error: call to 'floor' promotes float to double [performance-type-promotion-in-math-fn,-warnings-as-errors]`, which are fixed by using the C++ std math functions or our own math functions instead of the C math functions.
- Use `absolute` instead of `abs` and `fabs`.
- Use `std::floor` instead of `floor` and `floorf`.
- Use `std::ceil` instead of `ceil`, `ceilf` and `round_ceil`.
- Use `std::round` instead of `round` and `roundf`.
- Use `std::sin` instead of `sin` and `sinf`.
- Use `std::asin` instead of `asin` and `asinf`.
- Use `std::cos` instead of `cos` and `cosf`.
- Use `std::acos` instead of `acos` and `acosf`.
- Use `std::tan` instead of `tan` and `tanf`.
- Use `std::atan` instead of `atan` and `atanf`.
- Use `std::pow` instead of `pow` and `powf`.
- Use `std::log` instead of `log` and `logf`.
- Use `std::log2` instead of `log2` and `log2f`.
- Use `std::log10` instead of `log10` and `log10f`.
- Use `std::pow` instead of `pow` and `powf`.
- Use `std::sqrt` instead of `sqrt` and `sqrtf`.
- Use `std::fmod` instead of `fmod` and `fmodf`.
- Use `direction(Angle)` instead of `vec2(std::cos(Angle), std::sin(Angle))`.
- Use `length(vec2(x, y))` instead of `std::sqrt(x * x + y * y)`.
- Remove unused `NormalizeAngular` and `AngularDistance` functions.
Instead of returning the number of bytes written, which are platform specific, return `true` on success and `false` on failure, so no platform specific code is required when checking the result.
Use `bytes_be_to_uint` and `uint_to_bytes_be` instead.
As casting between `int` and `unsigned` preserves the bit representation of the value, it's not necessary to apply additional tricks to convert between `char` arrays and `int`.

Using `str_format` without format arguments is equivalent to `str_copy`, but using the latter is more efficient and readable.
As `str_format` also returns the result `str_utf8_fix_truncation`, i.e. the potentially truncated string length, the return value is also added to `str_copy` so existing invocations don't need to be adjusted.
6299: Show error message when downloaded map cannot be saved r=def- a=Robyt3
Check if deleting the old map file or renaming the temporary downloaded map fails. If so, show an error message which indicates that the user should delete the map file manually.
Sometimes downloaded map files seem to end up with wrong permissions, ownership or with read-only flag set, which makes the client unable to delete them.
Closes#5825.

6289: Fix `sv_vanilla_antispoof` for vanilla 0.6.5 clients r=def- a=Robyt3
This fixes issues that prevented vanilla 0.6.5 clients from joining DDNet servers with `sv_vanilla_antispoof 1` (closes#2074).
The dummy map was not valid. The size of the tiles and game layers was calculated incorrectly. The last member variable included in `CMapItemLayerTilemap` version 2 should be `m_Data`. Previously only the size of the member `m_aName` was subtracted from the total size, which was resulting in an incorrect item size, as the size of the following 5 members also needs to be subtracted.
The handshake messages were packed incorrectly. The message ID and the system flag were not added to the six packers that are passed to `SendMsgs`. The lines that are removed in this function seemed to assume that the message ID was already added but not packed, which was no longer the case. Presumable at some point `CMsgPacker` was changed without adapting the vanilla antispoof feature. Now, the message ID and system flag are properly packed when initially creating the message packers.
The `dummy_map` tool is improved to also print the generated map file's hashes and data as a C style array, so the data can immediately be copied to `network_server.cpp`.

As described in #5844, sometimes the color kept changing when activating a color picker.
By rounding the color components before packing them into an unsigned, the color only changes very little and only at most once when activating a color picker.
6217: Register application separately to specify its displayed name r=def- a=Robyt3
Follow-up from #6199.
Adding version information to the executable (#6203) doesn't result in the name being shown in the Windows settings. There is a separate registry key where applications can register a readable name.
