5374: Joystick support 🕹️ r=def- a=Robyt3

Port all the joystick support from vanilla:

- Joystick controls
  - support for up to 12 axis (we are using the low level SDL interface so we don't differentiate between X/Y axis, sliders etc.)
  - two axis can be used for X and Y cursor movement
  - cursor input ingame can be relative or absolute
  - support for binding up to 12 joystick buttons
  - support for binding up to 2 hats (each has 8 directions)
  - support for binding axis movement to controls (so you can move with one control stick and aim with the other)
  - multiple joysticks can be connected at the same time, but only one can be actively used, the selected joystick will be remembered based on a GUID
- Joystick UI integration
  - allow moving the UI cursor with the specified joystick axis
  - change `CComponent::OnMouseMove` to `OnCursorMove` to handle joystick separately with its own sensitivity settings
  - remove premultiplied mousesens everywhere
- Joystick settings menu (also: separate mouse and movement settings)

Other changes:

- Remove the old unused joystick implementation (with config variable `inp_joystick`).
- Remove an unused parameter.
- Add `CUIEx::DoScrollbarOption` and `IScrollbarScale`
  - renders label, current value and scrollbar
  - with linear and logarithmic scale implementations
  - used for the sensitivity and tolerance settings
  - could eventually be used for most scrollbar settings to reduce duplicate code
  - has flags for:
     - `SCROLLBAR_OPTION_INFINITE`: The scrollbar can be moved all the way to the right for another value that represents ∞. Internally this value is 0.
     - `SCROLLBAR_OPTION_NOCLAMPVALUE`: The scrollbar allows values outside the specified min/max range, e.g. the sensitivity settings can technically be as high as 100000 when set with the console.
- Add `CUIEx::DoScrollbarOptionLabeled`
  - a `DoScrollbarOption` for selecting from a finite number of options with a scrollbar
  - used for switching between relative and absolute input
  - might see more use in the future

5106: Fix dummy intended tick sent to server r=def- a=sjrc6

fixes https://github.com/ddnet/ddnet/issues/5044

Currently the dummy gives the server the wrong IntendedTick aka PredTick which (I think) makes it impossible for the server to correctly order inputs if they come early (i.e. if you're playing with high prediction margin).

Currently with dummy copy if you switch dummy with high prediction margin it will almost always desync, with this change it doesn't desync. 

The only reason dummy works at all is because it relies on this code in the server to change the tick that was sent to be the current game tick, if you remove it then dummy hammer and dummy copy breaks but normal players are unaffected.

e9b59e72ff/src/engine/server/server.cpp (L1632-L1633) 

I marked this PR as draft because it seems to cause some unexpected side effects:

with this change if you use dummy copy in solo part your dummy will be visually delayed, this doesn't change anything but it's different from how it was before and I don't understand why. 

the sound effects from hooking with dummy copy are also not as synced as they are with the wrong tick being sent (not sure why) 

I also didn't test all dummy mechanics or any advanced dummy binds which might somehow rely on the broken behavior. 


With wrong tick sent to server:

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.

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.

Merge #5075
5075: Switch to nanoseconds r=def- a=Jupeyy

Modern hardware is too fast, updates sometimes take less than a few microseconds.
It's easier in the long run if we use a bigger range to avoid calculation problems.

possibly f i x e s #5051 (needs testing from bencie for the main bug, but fixes what `@sjrc6` found)

Also took the moment to use more chrono so we can at some point switch to a typesafe time.

Hopefully I didnt miss any value ^^
