3279: Add a script to check for variable name style violations, fix some variable names r=def- a=heinrich5991
Didn't fix all variable names because there were far too many. Ideas? At least the second commit should probably go in.

2736: Let 0.7 clients fastdownload too r=def- a=Learath2
Easier than expected, I wonder why I didn't do this at the start.
Co-authored-by: Learath <learath2@gmail.com>
For legacy we sent the first packet once correctly, then the 2nd and 3rd
packet without the marker and token at the start, so they never worked.
For new 64 player serverinfo we sent all packets correctly but the 1st
packet twice.
Introduced in #1955.

`GameServer()->OnShutdown(true);` (which would wait on running threads to exit)
wasn't called if an error occured in the server init. Therefore `CServer` was
freed before the init-thread finished executing, causing a use after free from
`CSqlConnector::ms_ppSqlReadServers` pointing to `CServer->m_apSqlReadServers`.
2202: Send DDNet version early in the connection process r=Learath2 a=heinrich5991
This gets rid of the problem that we don't know whether we should send
full snapshots to clients because they haven't told us about them being
DDNet yet.

OK, maybe not actually remove because it is kept for fallback when the
new method isn't available.
The whole gametype parsing business had the same downsides as user agent
parsing on the web, hence I removed it while keeping behavior the same.
This allows servers to explicitly opt in or out of certain bug
workarounds and other client behavior. This increases the complexity of
different configurations that are available in the client (which is a
bad thing).
1466: Add colors for authed players. Deprecates #1299 r=def- a=Learath2
Not sure if a snap item is the best idea for this but it should help with not sending the data more then needed and keeping it properly updated. The colors aren't great now but we can fix that easily.

SHA256 was chosen because it is reasonably standard, the file names
don't explode in length (this rules out SHA512) and it is supported by
basically all versions of OpenSSL (this rules out SHA512/256 and SHA3).
The protocol is changed in a backward compatible way: The supporting
server sends the SHA256 corresponding to the map in the `MAP_DETAILS`
message prior to sending the `MAP_CHANGE` message. The client saves the
SHA256 obtained from the `MAP_DETAILS` message until the next
`MAP_CHANGE` message.
For servers not supporting this protocol, the client falls back to
simply opening maps like in the previous scheme.
Remove the `map_version` tool, it is not being used and would have been
a little bit effort to update.
Use the OpenSSL implementation of SHA256 if it is supported, otherwise
fall back to a public domain one.
Fix#1127.
This is done by HTTP POSTing to a location specified by
`sv_modhelp_url`. We also provide a `src/modhelp/server.py` which can
use theses POSTs to forward them to Discord servers.
The POST contains a JSON object payload, with the keys `"port"` which
contains the server port, `"player_id"` which contains the calling
player's client ID, `"player_name"` which contains the calling player's
nick and `"message"` which is the user-specified message.
Make JSON-escaping function public, add tests and fix bugs uncovered by
these tests.
Supersedes #1129.
