6284: Ensure integer wrapping instead of preventing overflow/underflow r=heinrich5991 a=Robyt3
As the integer overflow/underflow in `UndiffItem` can happen during normal gameplay, we should in this case neither ignore the snapshot delta nor show an error message.
Instead of depending on the particular compiler doing integer wrapping, when integer overflows or underflows occur, we make it part of the design, by casting to `unsigned`, which ensures that integer wrapping is being used.

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`.

6253: Allow navigating listboxes when no item is currently selected r=Chairn a=Robyt3
It was no longer possible to navigate listboxes (e.g. the server browser) by using keyboard hotkeys when no item is currently selected due to a regression from #6240.
Additionally, it was not possible even before #6240 to start navigating the server browser with the keyboard afer manually clearing the server address input, which is now possible as well.

Add "Copy info" buttons to server browser and ingame menu to copy the server info of the selected/current server to the clipboard.
The margins around the server browser details are improved.
Closes#5440.
Replace existing listbox implementations (`CMenus::UiDoListbox*` and `HandleListInputs` functions) with `CListBox` from upstream.
Reimplement additional feature that was already present in ddnet: page up/down, home and end key handling.
Affects the following lists:
- server browser
- server browser scoreboard
- server browser friends
- country / region selection popup (server browser filter)
- player skin list
- player country / region list
- theme list
- assets list
- graphics resolutions list
- dropdown menus (e.g. graphics fullscreen mode)
- ingame player list
- vote options list
- kick/specvote lists
- ghost list
- language list (in settings and in popup on first launch)
- demo browser
- editor file browser (saving, loading, adding images / sounds)
- The search / filename input is also improved so navigating a filtered list works correctly by porting the logic from upstream.
There are minor changes to the visual appearance of some lists, due to changed margins.
The vertical alignment of some list item texts is improved so the text is centered vertically.

When the demo recording is not stopped properly (e.g. client crashes during recording), the timeline markers and the demo length are not updated.
The length is always set to zero when starting the recording, but uninitialized memory is written for the timeline markers, which causes these demos to likely show the maximum number of markers with some markers possibly being outside the ticks that the demo contains.
This is fixed by initially setting all timeline marker data to zero when starting the recording.
Swap mathematical operations to avoid multiplication by `1000`. As `time_freq()` returns the nanoseconds in a second (1e9), first dividing this number by 1000 does not lose any precision.
Also ensure that `IntendedTick` is in the valid range of ticks.

To avoid adding back the include in `teamscore.h`, the function definitions are moved to the cpp file. Both definitions are moved for consistency.

6213: Fix scoreboard showing wrong best time r=Zwelf a=def-
by requesting the best time again when it initially failed. This is still not perfectly accurate since a player on another server can get a better time, which will not get updated when the current server had no database problems.

> The best time shown on the scoreboard on the turkish server on a

> min (it's correct on ger2 server)
So the way it works is that the best time is loaded from database when loading map. Additionally it gets updated when a new finish is done. If the initial load failed, but a finish with 30 min is done on the server, we get this result
