2276: Fix segmentation fault when creating sql tables failed r=heinrich5991 a=Zwelf
`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`.
Fixes#2271
Note that the server exits when creating tables failed. Since the tables are created by default, it has to be disabled explicitly (e.g. `add_sqlserver r teeworlds record teeworlds PASSWORD "localhost" 3306 0`) if the servers should start even when the database connection fails.

2247: Thread safe SQL interaction r=def- a=Zwelf
This PR intends to make the database interaction thread safe and optimizes some SQL queries. This is still a WIP, but since it is a rather big PR I wanted to get feedback early on.
Benefits:
* remove race conditions leading to undefined behavior and potential crashes
* logging game related database results in teehistorian would be possible
Behavior change:
* /top5team prints ranks in reverse order when passing a negative number (like /top5, /top5points)
* Optimize SQL statements for /rank /teamrank /top5 /top5team /points /top5points
* /load without parameters doesn't pass the SQL error to the user (as most other functions)
* Simplify IScore interface
* Add UUID to /save table (update of database schema necessary):
```
ALTER TABLE record_saves ADD SaveID varchar(64);
```
* /save immediately kills team and loads it again if the database insert fails.
still TBD:
* [x] saving (team) score when finishing
* [x] loading team save
* [x] loading initial time and birthday check
* [x] /map and random map votes
* [x] RFC: generate a passphrase (2-3 word) if save-code exists or no save-code is given making /save failures much more rare and save-codes more secure
* [x] clean up code (removing now unused structs, ordering of functions in IScore)

Add libnotify support for linux client
Also unify notification management
Make libnotify mandatory for the client. It is installed on 100% of Arch
Linux systems and on 70% of Debian systems. I'd guess the remaining
Debian systems are servers.
Detect dependent libraries of `libnotify` using `pkg-config`. Remove
library-specific code from the game module. Decrement refcount for
libnotify notification object before leaving the function.
2119: Change last render logic, when inactive r=def- a=Jupeyy
Just a small fix to let the client not try to get high fps, when it "thinks" it didn't render for a long time.
(is still affected by the SDL check "if window has input" at the cl_refresh_rate calculation, so not a 100% fix).

I added a new option to open a new demo file only when connect to server (include map changing), this is disabled by default, and can use `cl_auto_demo_on_connect 1` to open. It works only when `cl_auto_demo_record` open.

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).

Instead show □ (white square, 0x25a1) as replacement character

Number of minutes of active racing time before being asked to confirm
disconnecting, disconnecting dummy or quitting through GUI. Defaults to
20 minutes, -1 to disable, 0 to always enable.
Also removed confirmation to quit when in main menu, except when having

Spectate and kill should already be safe thanks to server-side kill
protection.
- As requested by qshar and KoG players
- Similar to DDNet tab
- Info fetched from servers-kog entry from https://info.ddnet.tw/info
- Also supports countries and types
- Doesn't inform whether map has been finished
- Generalized the code a bit but it's still ugly
- Depends on #1533, also shows KoG servers as official/verified
And persist the result. Helps with the workflow described by Shyzo on
Discord:
> I mean after i press ctrl-f or fetch info. then i want to sort by marker (from ... to 0) and just delete every demo without a marker. either in a whole (not possible i think) or just one by one. but I think after deleting one demo the order of demos change again
> so i have to fetch info again, delete one. fetch info again. delete one

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.

Replace `mem_free` by `free`, and `mem_alloc` by `malloc` or `calloc`
(the latter one being used to allocate a zeroed array of elements,
sometimes, this makes a call to `mem_zero` superfluous).
This results in having to remove `mem_stats` which previously recorded
the number of allocations and their size that the Teeworlds code did
directly.
Remove OOM handling in `src/game/client/components/binds.cpp`.
Remove needless copying in the CSV code in
