5658: Fix game freezing up on duplicate snapshot r=def- a=Fireball-Teeworlds

If a duplicate snapshot is received (for the same tick), we add both to the SnapshotStorage and end up with the same snapshot as both Cur and Prev. This results in GameInfraTick returning "inf" and results in "NaN" downstream in a few places, getting the CollLine logic stuck.

Some debug info (tcpdump, gdb, perf): https://gist.github.com/Fireball-Teeworlds/ad0016d2551a2e4d4cb5691023493856

Apparently this doesn't really happen in the wild, unless you have a buggy network stack. In which case it happens frequently enough to pinpoint the issue :D

 (fixes #5657)

Robert Müller 3863d41623 Validate snapshot size and member variables and demo snapshots
Add `CSnapshot::IsValid` to check if a snapshot unpacked from a snapshot delta or demo is valid:
- ensure number of items and data size are not negative
- ensure that the actual size of the snapshot matches the size derived from its member variables
- ensure item offsets are within the valid range
- ensure item sizes are not negative

Add `CSnapshot::TotalSize` and `CSnapshot::OffsetSize` utility functions.

Minor improvements to related error messages.

Fixes buffer overflow:

5544: Replaced float array with appropriate struct (vec or color) r=def- a=Chairn

I mostly touched the code in the graphic part for array of 2 floats into vec2.
For color, i replaced array of 4 floats with ColorRGBA where it made sense.

I had to change the logic order in `src/engine/client/graphics_threaded.cpp:1113` due to operator= from vec2 to vec3. I didn't see any visual change.

5486: Switch to loading screen, when map creation takes too long r=def- a=Jupeyy

Same as #4941 

It doesn't directly fix the issue described in #5478, it does however not trigger it anymore. it's still a bug in our code unrelated  to this. This just triggered the UB from the issue as  `@ardadem` confirmed, SDL received a SDL_QUIT (`[2022-06-23 20:26:31][test]: sdl closed my client, but why xd`)

Now we have a confirmed case that making the window unresponsive can create weird behavior. Similar to the other pr switch to a loading screen after 500ms (this time without menu background map tho, since the menu background map calls the same code).

We really need some fancy loading screen for such situations, even tho they are rare xD

Jupeyy 65ad57a448 Change from pnglite to libpng for PNG reading
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.

Robert Müller 3f1f94c9d8 Fix segfault in SDL_JoystickClose on client quit
Instead of closing the joysticks manually, use `SDL_QuitSubSystem(SDL_INIT_JOYSTICK)` to quit the entire subsystem, which will also close all joysticks correctly.

The engine input destructor is replaced with a `Shutdown` method so we can control when it is called, i.e. before calling `SDL_Quit`, which forcefully quits all subsystems.

`CJoystick::Close` is removed as we don't need to close joysticks manually anymore.

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:

With correct tick:

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,

`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.

`--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": {

					"size": 5805
				},
				"version": "0.6.4, 16.0.3",
				"clients": []
			}
		}
	]
}
```

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 ^^

No message if we don't have STUN servers.

"Trying to determine UDP connectivity..." if no answer has been received
from the STUN server yet and it hasn't timed out yet.

"UDP seems to be filtered." if the STUN request has timed out.

"UDP and TCP IP addresses seem to be different. Try disabling VPN,
proxy or network accelerators." if the STUN request has returned an IP
address different from the one obtained via HTTP from info2.ddnet.tw.

"No answer from server yet." otherwise, if the STUN request has returned

5085: New DDRace HUD r=def- a=C0D3D3V

If you want to test this PR, you have to test it on a Server that includes this PR too.

Textures are made by Ravie 

Here a showcase video with most parts shown: https://youtu.be/gPTVj-s3pgc 

Added to the new HUD
- A display of the weapons available to the player
- The weapon the player is carrying is highlighted
- Indicators for the special abilities of the player (Endless Hook, Endless Jumps, Jetpack, Teleport Weapons)
- Indicators for abilities taken away from the player (Deep/Life Freeze, No Hook, No Weapons collision, No Collision)
- Control indicators for dummy controls (dummy hammer, dummy copy) (bottom right)
- Jump indicator (max 10 jumps ar displayed, and greyed out as soon as a jump is used) 
- Ninja status bar that indicates how long a player is capable of using ninja (next to the ninja sword)
- Freeze status bar that indicates the thawing time of a player (below player)
- Movement Information can be displayed in a clean way above the mini score HUD (Position, Speed, Target Angle)
- Indicator if you are in practice mode

The complete HUD also works for players you spectate

I Added a new NetObj since the predicted values are not perfect and would make the display of the information a lot less good: DDNetCharacterDisplayInfo that contains the following information
```
NetIntRange("m_JumpedTotal", -2, 255),
NetTick("m_NinjaActivationTick"),
NetTick("m_FreezeTick"),
NetBool("m_IsInFreeze"),
NetBool("m_IsInPracticeMode"),

NetIntAny("m_TargetX"),  # used for the Movement Information display
NetIntAny("m_TargetY"),
NetIntAny("m_RampValue"),
```
So if someone has an idea what data we could also need in the client for making the display more nice, now is the right moment to add more data to this network object.

A few screenshots:
