2465: Sqlite3 support and prepared statements r=heinrich5991 a=Zwelf
This PR changes the abstraction layer of the score backend to thin abstractions over the MySQL and SQLite3 library. It executes all Queries in one worker thread making it easier to use the ddnet thread pool. This doesn't change much, because each the mysql-connection was locked with `m_SqlLock` beforehand, serializing writes and reads respectively.
Behavior change (even though I tried to minimize them):
* `sv_use_sql` is used to determine if mysql server should be added
* `sv_sql_failure_file` is replaced by `sv_sqlite_file`
* `sv_sqlite_file` is either used as a backup server when `sv_use_sql` is enabled or as the primary read+write server when `sv_use_sql` is disabled
* `/load` now escapes the like-string
Since I am not good at designing config file commands, I would appreciate feedback on this part.
WIP:
* [x] rewrite SQL statements to work in both MySQL and SQLite (preferable just ANSI-SQL)
* [x] create tables (`COLLATE BINARY` and encoding info)
* [x] store rank (UPSERT for points)
* [x] load birthday (different function in sqlite for time handling)
* [x] `/mapinfo` (`convert(? using utf8mb4) COLLATE utf8mb4_general_ci`)
* [x] `/map` (`convert(? using utf8mb4) COLLATE utf8mb4_general_ci`)
* [x] store teamrank (`GROUP_CONCAT`)
* [x] `/teamrank` (`GROUP_CONCAT`)
* [x] ~`/top5team` (`GROUP_CONCAT`)~ doesn't contain GROUP_CONCAT
* [x] `/times` (`UNIX_TIMESTAMP`)
* [x] `/load` without any arguments (`UNIX_TIMESTAMP`)
* [x] all commits compiling, making future bisect easier
* [x] write a sqlite_to_mysql script
* [x] write an old_file_server to sqlite script
* [x] gracefully shutdown DbPool

2331: Enable rpath on Linux for shipping SDL2 shared lib r=heinrich5991 a=def-
I guess we should have a way to say when we want to build against the
static sdl2? Or we just ship SDL2 for the ddnet.tw releases as well. I'd
be fine with the latter, but it adds a few MB probably.

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.
ABI check failed, CMAKE_SIZEOF_VOID_P was thus not set and we look for
libs in wrong directory. Something seems to be wrong with the C/C++
compilers Travis is using. Not sure how to figure out more closely.
1620: Rewrite of prediction code, with additional prediction (updated) r=def- a=trml
This is a reworked attempt at a rewrite of the prediction code (#464), to allow for more client side prediction. It doesn't fix the duplication of server code, but the client code should otherwise be cleaner. This includes separating prediction code out of gamecore/gameclient, and a refactor of the rendering of predicted characters.
There is also prediction for some new things, and some other changes:
- prediction of laser, shotgun, ninja, fng hammer, pickups and ddrace tiles (freeze/unfreeze tiles with cl_predict_freeze)
- laser and bullets are rendered when you fire them and bullets don't go through walls (when both cl_antiping_grenade and cl_antiping_weapons are enabled)
- antiping for flags
- prediction of dummy input
- an additional smoothing option that attempts to make antiping less jumpy (cl_antiping_smooth)

1621: Actually enable -Wuseless-cast r=heinrich5991 a=def-
It's not supported in C and we only checked using a C compiler.

- Explanations by Lady Saavik taken from https://ddnet.tw/explain/
- CCW/CW were mixed up in enum names, fixed
- Make sure that the texts fits, otherwise reduce font size
- Still need explanations for Portal tiles
