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.

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.

Saves should not be loadable from one to the other.
Requires:
ALTER TABLE record_race ADD COLUMN DDNet7 BOOL DEFAULT FALSE AFTER GameID;
ALTER TABLE record_teamrace ADD COLUMN DDNet7 BOOL DEFAULT FALSE AFTER GameID;
ALTER TABLE record_saves ADD COLUMN DDNet7 BOOL DEFAULT FALSE AFTER Server;
