This allows every game server to provide its own HTTPS server for map
downloads. Since the ingame protocol for downloading map data is very
inefficient, this is desirable. Previously, only servers hosted by DDNet
could benefit from this.
Security concerns:
- Attackers can find out whether a given HTTPS GET request matches a
known answer.
This isn't deemed to be problematic as no cookies for authentication
are sent and only the whole response can be matched.
- Sending requests to honeypot URLs to get people in legal trouble.
This seems to be already possible with HTML image embeds, so it can't
be that bad™.
- Downloading huge files, filling up a player's disk. The players might
cancel when seeing huge files.
There's a generous limit of 1 GiB per map file.
- Downloading huge files transparently compressed with gzip. See above.
Fixes#5812.

The `CServer::GetClientVersion` method needs the `version.h` include, so it's moved from the header to the source file, so the include can be removed from the header.
The `GetClientVersion` method is often called with the same `Client != SERVER_DEMO_CLIENT ? GetClientVersion(Client) : CLIENT_VERSIONNR` expression, which also needs the `version.h` include. This expression is moved inside the method, so the include can be removed from all the server entities' and player code.
The `CGameContext::GetClientVersion` method is made a delegate to reduce duplicate code.
The includes of the server entities are also organized further.
Fix pointer and pointer array variable naming
Huge renaming to match our rules
Used regex: (?!(return|delete)\b)\b\w+ (m_|ms_|g_|gs_|s_)[^a]\w+\[
(?!(return|delete)\b)\b\w+ (?!(m_|ms_|g_|gs_|s_))[^a]\w+\[
Further format static variables
Format almost all pointer names accordingly
Used regex: (?!(return)\b)\b\w+

Revert to SCREAMING_SNAKE_CASE and reinstate dead code
The sixup translated player flags were previously applied in `OnDirectInput` directly to the player input data.
However, the input data has already been copied at that point, so predicted inputs were using the incorrect flags.
This is fixed by moving the player flags translation to `OnClientPrepareInput`, which is called first and only once on each new player input before it is copied.
The flags were only being updated based on rather arbitrary conditions, so they could never reset to zero or reduced.
The flags are now always updated. The flags are only used in the output of the `status` command.
4829: Added map_replace_area tool r=def- a=sctt
Motivation:
sometimes mappers need to copy a certain area from a map to another (but also to a different position of the same map).
that's very time consuming on complex maps, as tiles and quads layers have to be manually copied one by one.
map_replace_area is designed to automatically replace all the tiles and quads from a specific area to another.
`Usage: map_replace_area <from_map> <from_x> <from_y> <to_map> <to_x> <to_y> <width> <height> <output_map>`
PoW screenshots attached below.
note: for the moment map_replace_area suppose that you are working on the same map (that's what i needed), that means source and destination maps must have the same layers structure, or else an error is returned.
but i understand it might be useful to also work on totally different maps, in that case users must be able specify layers they want to consider by associating source map layers to destination map layers (by using a config file maybe).
i'm probably going to make another PR to add this enhancement in the future.

5343: Add rcon and chat to integration test r=def- a=ChillerDragon
Add more action to the integration test script: chat messages, chat commands, rcon commands.
This unlocks more code coverage at runtime to catch asan issues.
It adds a very restrictive regex on the log format. But I am happy to maintain that in case changes to the log output happen.
The current version is already supporting heinrichs refactor https://github.com/ddnet/ddnet/pull/5036
Also ensure chat messages arrive in the correct format. Would have catched the following issues:

5465: Change from pnglite to libpng for PNG reading r=def- a=heinrich5991
This is desirable mainly because libpng is maintained and pnglite is
not. pnglite was last updated in 2007 (15 years ago) and probably has a
lot of security vulnerabilities.
libpng is an actively maintained library also used by browsers like
Firefox or Chromium, so it's less likely to contain security
vulnerabilities, also it's more likely to be packaged by Linux
distributions.
This also refuses to load images of types not supported by pnglite,
which allows us to think about backward compatibility while also
introducing libpng.

5406: Remove namespace tw r=Jupeyy a=heinrich5991
It didn't have a clear role, it just acted as a distinguisher between
two functions with the same name.
Rename `tw::time_get` to `time_get_nanoseconds` and delete the old
`time_get_nanoseconds`. Move `CCmdlineFix` and the typed
`net_socket_read_wait` function to the global namespace.

Also delete it explicitly when `sv_register` is set to register via less
protocols.
On shutdown, wait at most 1 second for the masterserver to respond,
otherwise allow up to 15 seconds.

5252: Use std::vector instead of array, remove base/tl/array.h, algorithm.h, allocator.h, range.h r=def- a=Robyt3
Replaces all usages of `array` with `std::vector`.
I adjusted variable names of variables I changed to use the `v` prefix. Not so in the editor however, as there are already many changes due to clang-tidy enforcing the use of for-each loops.
This allows us to remove all remaining `base/tl` headers except `threading.h`.
Clang-tidy now finds `clang-analyzer-cplusplus.NewDelete` (Use of memory after it is freed), which is also fixed here, though it appears to be a false-positive.
This last remaining usages of `goto` are also removed.
