Merge #5246
5246: Use std::vector instead of sorted_array, remove base/tl/sorted_array.h r=def- a=heinrich5991

This replaces all usages of `sorted_array` with `std::vector`. This requires the following general changes:

- `add_unsorted` is replaced with `push_back`.
- `add` is replaced with `push_back` and subsequent `sort` or `stable_sort` must be ensured.
  - In some cases, immediately sorting the entire list after adding an item was unavoidable. Previously items were added at the correct position, which was O(N) because all items after the inserted one had to be moved in any case.
- `sort_range` is replaced with `sort` or `stable_sort`.
- `size` returns a `size_t` instead of `int`, so to fix sign comparison warnings, casts are added where necessary or types of loop variables are changed to `size_t` where possible. For-each loops are also used where possible / where required by clang-tidy.
- `find_binary` is replaced with `std::equal_range`. This can only find items of the same type, so some wrappers, that only have the relevant fields set, need to be created for searching.

In terms of behavior, this should not change anything, except maybe `CLocalizationDatabase` for the better. As far as I understand it, at lot of the code there was not doing anything. It assumes that binary search can return a range of multiple entries, but the equality/comparison function is based on hash and context hash. This means that any item in this range will match the given hash and context hash already, so all of the following checks are redundant. I changed this to first do a lookup with the hash and context hash and if that fails do another lookup with the default context hash.

I have also already replaced `base/tl/array.h` with `std::vector`, removing all of `base/tl` except `threading.h`. I'll make a separate PR later because this caused a lot more changes especially in the editor that I first want to test and review myself.

Naming of `array`/`sorted_array`/`std::vector` variables was rather inconsistent (sometimes prefix `a` or `l` is used), so ~~I chose to not use any prefix for all new `std::vector`s~~ heinrich5991 left them as-is.

5063: Reworked Draggers and Turrets AND show always hooks if they are in the field of view  r=def- a=C0D3D3V

Fixes #3622, #4723 #4798 and #5054

Here you can find a comparison video with 16.0.3: https://youtu.be/bYwLB1cEMI8

This now also includes the changes from https://github.com/ddnet/ddnet/pull/4980 
So please also see my monologue here: https://github.com/ddnet/ddnet/pull/4980

Physic that got changed by this PR:
- Solo players are not included in the calculation of the next team players to the dragger/turrets. This does not affect any map.
- Turrets get switched correctly if players are solo
- Plasma bullets fired by turrets on solo player only explode for solo players and the other way around (except if they unsolo)
- Plasma bullets can no longer be intercepted by other teams 
- Turrets can shot now independently at the speed of sv_plasma_per_sec for  every team and every solo player


This should be tested by some more players before it get merged!

This reduces the use of snap id's tested here: https://youtu.be/G3nVtdH0--Q 
from 16000 to 69
test with the new dragger: https://youtu.be/mzNrDHP7HQs
I did not add the terminal of the server because you basically see no change in the used snap ids 
The videos are with cl_predict off

Comparison of the new turrets: https://streamable.com/8us8lk

Merge #5064
5064: Add HTTP masterserver registering and HTTP masterserver r=def- a=heinrich5991

Registering
-----------

The idea is that game servers push their server info to the
masterservers every 15 seconds or when the server info changes, but not
more than once per second.

The game servers do not support the old registering protocol anymore,
the backward compatibility is handled by the masterserver.

The register call is a HTTP POST to a URL like
`https://master1.ddnet.tw/ddnet/15/register` and looks like this:
```http
POST /ddnet/15/register HTTP/1.1
Address: tw-0.6+udp://connecting-address.invalid:8303
Secret: 81fa3955-6f83-4290-818d-31c0906b1118
Challenge-Secret: 81fa3955-6f83-4290-818d-31c0906b1118:tw0.6/ipv6
Info-Serial: 0

{
	"max_clients": 64,
	"max_players": 64,
	"passworded": false,
	"game_type": "TestDDraceNetwork",
	"name": "My DDNet server",
	"map": {
		"name": "dm1",
		"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
		"size": 5805
	},
	"version": "0.6.4, 16.0.3",
	"clients": []
}
```

The `Address` header declares that the server wants to register itself as
a `tw-0.6+udp` server, i.e. a server speaking a Teeworlds-0.6-compatible
protocol.

The free-form `Secret` header is used as a server identity, the server
list will be deduplicated via this secret.

The free-form `Challenge-Secret` is sent back via UDP for a port forward
check.  This might have security implications as the masterserver can be
asked to send a UDP packet containing some user-controlled bytes. This
is somewhat mitigated by the fact that it can only go to an
attacker-controlled IP address.

The `Info-Serial` header is an integer field that should increase each
time the server info (in the body) changes. The masterserver uses that
field to ensure that it doesn't use old server infos.

The body is a free-form JSON object set by the game server. It should
contain certain keys in the correct form to be accepted by clients. The
body is optional if the masterserver already confirmed the reception of
the info with the given `Info-Serial`.

Not shown in this payload is the `Connless-Token` header that is used
for Teeworlds 0.7 style communication.

Also not shown is the `Challenge-Token` that should be included once the
server receives the challenge token via UDP.

The masterserver responds with a `200 OK` with a body like this:

```
{"status":"success"}
```

The `status` field can be `success` if the server was successfully
registered on the masterserver, `need_challenge` if the masterserver
wants the correct `Challenge-Token` header before the register process
is successful, `need_info` if the server sent an empty body but the
masterserver doesn't actually know the server info.

It can also be `error` if the request was malformed, only in this case
an HTTP status code except `200 OK` is sent.

Synchronization
---------------

The masterserver keeps state and outputs JSON files every second.

```json
{
	"servers": [
		{
			"addresses": [
				"tw-0.6+udp://127.0.0.1:8303",
				"tw-0.6+udp://[::1]:8303"
			],
			"info_serial": 0,
			"info": {
				"max_clients": 64,
				"max_players": 64,
				"passworded": false,
				"game_type": "TestDDraceNetwork",
				"name": "My DDNet server",
				"map": {
					"name": "dm1",
					"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
					"size": 5805
				},
				"version": "0.6.4, 16.0.3",
				"clients": []
			}
		}
	]
}
```

`servers.json` (or configured by `--out`) is a server list that is
compatible with DDNet 15.5+ clients. It is a JSON object containing a
single key `servers` with a list of game servers. Each game server is
represented by a JSON object with an `addresses` key containing a list
of all known addresses of the server and an `info` key containing the
free-form server info sent by the game server. The free-form `info` JSON
object re-encoded by the master server and thus canonicalized and
stripped of any whitespace characters outside strings.

```json
{
	"kind": "mastersrv",
	"now": 1816002,
	"secrets": {
		"tw-0.6+udp://127.0.0.1:8303": {
			"ping_time": 1811999,
			"secret": "42d8f991-f2fa-46e5-a9ae-ebcc93846feb"
		},
		"tw-0.6+udp://[::1]:8303": {
			"ping_time": 1811999,
			"secret": "42d8f991-f2fa-46e5-a9ae-ebcc93846feb"
		}
	},
	"servers": {
		"42d8f991-f2fa-46e5-a9ae-ebcc93846feb": {
			"info_serial": 0,
			"info": {
				"max_clients": 64,
				"max_players": 64,
				"passworded": false,
				"game_type": "TestDDraceNetwork",
				"name": "My DDNet server",
				"map": {
					"name": "dm1",
					"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
					"size": 5805
				},
				"version": "0.6.4, 16.0.3",
				"clients": []
			}
		}
	}
}
```

`--write-dump` outputs a JSON file compatible with `--read-dump-dir`,
this can be used to synchronize servers across different masterservers.
`--read-dump-dir` is also used to ingest servers from the backward
compatibility layer that pings each server for their server info using
the old protocol.

The `kind` field describe that this is `mastersrv` output and not from a
`backcompat`. This is used for prioritizing `mastersrv` information over
`backcompat` information.

The `now` field contains an integer describing the current time in
milliseconds relative an unspecified epoch that is fixed for each JSON
file. This is done instead of using the current time as the epoch for
better compression of non-changing data.

`secrets` is a map from each server address and to a JSON object
containing the last ping time (`ping_time`) in milliseconds relative to
the same epoch as before, and the server secret (`secret`) that is used
to unify server infos from different addresses of the same logical
server.

`servers` is a map from the aforementioned `secret`s to the
corresponding `info_serial` and `info`.

```json
[
	"tw-0.6+udp://127.0.0.1:8303",
	"tw-0.6+udp://[::1]:8303"
]
```

`--write-addresses` outputs a JSON file containing all addresses
corresponding to servers that are registered to HTTP masterservers. It
does not contain the servers that are obtained via backward
compatibility measures.

This file can be used by an old-style masterserver to also list
new-style servers without the game servers having to register there.

An implementation of this can be found at
https://github.com/heinrich5991/teeworlds/tree/mastersrv_6_backcompat
for Teeworlds 0.5/0.6 masterservers and at
https://github.com/heinrich5991/teeworlds/tree/mastersrv_7_backcompat
for Teeworlds 0.7 masterservers.

All these JSON files can be sent over the network in an efficient way
using https://github.com/heinrich5991/twmaster-collect. It establishes a
zstd-compressed TCP connection authenticated by a string token that is
sent in plain-text. It watches the specified file and transmits it every
time it changes. Due to the zstd-compression, the data sent over the
network is similar to the size of a diff.

Implementation
--------------

The masterserver implementation was done in Rust.

The current gameserver register implementation doesn't support more than
one masterserver for registering.

heinrich5991 6b65ccb945 Add HTTP masterserver registering and HTTP masterserver
Registering
-----------

The idea is that game servers push their server info to the
masterservers every 15 seconds or when the server info changes, but not
more than once per second.

The game servers do not support the old registering protocol anymore,
the backward compatibility is handled by the masterserver.

The register call is a HTTP POST to a URL like
`https://master1.ddnet.tw/ddnet/15/register` and looks like this:
```json
POST /ddnet/15/register HTTP/1.1
Address: tw-0.6+udp://connecting-address.invalid:8303
Secret: 81fa3955-6f83-4290-818d-31c0906b1118
Challenge-Secret: 81fa3955-6f83-4290-818d-31c0906b1118:tw0.6/ipv6
Info-Serial: 0

{
	"max_clients": 64,
	"max_players": 64,
	"passworded": false,
	"game_type": "TestDDraceNetwork",
	"name": "My DDNet server",
	"map": {
		"name": "dm1",
		"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
		"size": 5805
	},
	"version": "0.6.4, 16.0.3",
	"clients": []
}
```

The `Address` header declares that the server wants to register itself as
a `tw-0.6+udp` server, i.e. a server speaking a Teeworlds-0.6-compatible
protocol.

The free-form `Secret` header is used as a server identity, the server
list will be deduplicated via this secret.

The free-form `Challenge-Secret` is sent back via UDP for a port forward
check.  This might have security implications as the masterserver can be
asked to send a UDP packet containing some user-controlled bytes. This
is somewhat mitigated by the fact that it can only go to an
attacker-controlled IP address.

The `Info-Serial` header is an integer field that should increase each
time the server info (in the body) changes. The masterserver uses that
field to ensure that it doesn't use old server infos.

The body is a free-form JSON object set by the game server. It should
contain certain keys in the correct form to be accepted by clients. The
body is optional if the masterserver already confirmed the reception of
the info with the given `Info-Serial`.

Not shown in this payload is the `Connless-Token` header that is used
for Teeworlds 0.7 style communication.

Also not shown is the `Challenge-Token` that should be included once the
server receives the challenge token via UDP.

The masterserver responds with a `200 OK` with a body like this:

```
{"status":"success"}
```

The `status` field can be `success` if the server was successfully
registered on the masterserver, `need_challenge` if the masterserver
wants the correct `Challenge-Token` header before the register process
is successful, `need_info` if the server sent an empty body but the
masterserver doesn't actually know the server info.

It can also be `error` if the request was malformed, only in this case
an HTTP status code except `200 OK` is sent.

Synchronization
---------------

The masterserver keeps state and outputs JSON files every second.

```json
{
	"servers": [
		{
			"addresses": [
				"tw-0.6+udp://127.0.0.1:8303",
				"tw-0.6+udp://[::1]:8303"
			],
			"info_serial": 0,
			"info": {
				"max_clients": 64,
				"max_players": 64,
				"passworded": false,
				"game_type": "TestDDraceNetwork",
				"name": "My DDNet server",
				"map": {
					"name": "dm1",
					"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
					"size": 5805
				},
				"version": "0.6.4, 16.0.3",
				"clients": []
			}
		}
	]
}
```

`servers.json` (or configured by `--out`) is a server list that is
compatible with DDNet 15.5+ clients. It is a JSON object containing a
single key `servers` with a list of game servers. Each game server is
represented by a JSON object with an `addresses` key containing a list
of all known addresses of the server and an `info` key containing the
free-form server info sent by the game server. The free-form `info` JSON
object re-encoded by the master server and thus canonicalized and
stripped of any whitespace characters outside strings.

```json
{
	"kind": "mastersrv",
	"now": 1816002,
	"secrets": {
		"tw-0.6+udp://127.0.0.1:8303": {
			"ping_time": 1811999,
			"secret": "42d8f991-f2fa-46e5-a9ae-ebcc93846feb"
		},
		"tw-0.6+udp://[::1]:8303": {
			"ping_time": 1811999,
			"secret": "42d8f991-f2fa-46e5-a9ae-ebcc93846feb"
		}
	},
	"servers": {
		"42d8f991-f2fa-46e5-a9ae-ebcc93846feb": {
			"info_serial": 0,
			"info": {
				"max_clients": 64,
				"max_players": 64,
				"passworded": false,
				"game_type": "TestDDraceNetwork",
				"name": "My DDNet server",
				"map": {
					"name": "dm1",
					"sha256": "0b0c481d77519c32fbe85624ef16ec0fa9991aec7367ad538bd280f28d8c26cf",
					"size": 5805
				},
				"version": "0.6.4, 16.0.3",
				"clients": []
			}
		}
	}
}
```

`--write-dump` outputs a JSON file compatible with `--read-dump-dir`,
this can be used to synchronize servers across different masterservers.
`--read-dump-dir` is also used to ingest servers from the backward
compatibility layer that pings each server for their server info using
the old protocol.

The `kind` field describe that this is `mastersrv` output and not from a
`backcompat`. This is used for prioritizing `mastersrv` information over
`backcompat` information.

The `now` field contains an integer describing the current time in
milliseconds relative an unspecified epoch that is fixed for each JSON
file. This is done instead of using the current time as the epoch for
better compression of non-changing data.

`secrets` is a map from each server address and to a JSON object
containing the last ping time (`ping_time`) in milliseconds relative to
the same epoch as before, and the server secret (`secret`) that is used
to unify server infos from different addresses of the same logical
server.

`servers` is a map from the aforementioned `secret`s to the
corresponding `info_serial` and `info`.

```json
[
	"tw-0.6+udp://127.0.0.1:8303",
	"tw-0.6+udp://[::1]:8303"
]
```

`--write-addresses` outputs a JSON file containing all addresses
corresponding to servers that are registered to HTTP masterservers. It
does not contain the servers that are obtained via backward
compatibility measures.

This file can be used by an old-style masterserver to also list
new-style servers without the game servers having to register there.

An implementation of this can be found at
https://github.com/heinrich5991/teeworlds/tree/mastersrv_6_backcompat
for Teeworlds 0.5/0.6 masterservers and at
https://github.com/heinrich5991/teeworlds/tree/mastersrv_7_backcompat
for Teeworlds 0.7 masterservers.

All these JSON files can be sent over the network in an efficient way
using https://github.com/heinrich5991/twmaster-collect. It establishes a
zstd-compressed TCP connection authenticated by a string token that is
sent in plain-text. It watches the specified file and transmits it every
time it changes. Due to the zstd-compression, the data sent over the
network is similar to the size of a diff.

Merge #5155
5155: Remove cl_show_console and -c / --console command line options, attach to existing console r=heinrich5991 a=Robyt3

Alternative to #5154. 

Closes #5150.

If you want to open the client with a console window, instead create a new shortcut with the following target:

```
cmd /c "C:\path\to\your\DDNet.exe"
```

You can change the icon of the shortcut to the DDNet icon in the properties of the shortcut file.
