Add tests. Unify behavior of `fs_remove` across operating systems to
only remove files, not directories. Previously on Linux, it would also
delete directories.
Summary
=======
The idea of this is that clients will not have to ping each server for
server infos which takes long, leaks the client's IP address even to
servers the user does not join and is a DoS vector of the game servers
for attackers.
For the Internet, DDNet and KoG tab, the server list is entirely fetched
from the master server, filtering out servers that don't belong into the
list.
The favorites tab is also supposed to work that way, except for servers
that are marked as "also ping this server if it's not in the master
server list".
The LAN tab continues to broadcast the server info packet to find
servers in the LAN.
How does it work?
=================
The client ships with a list of master server list URLs. On first start,
the client checks which of these work and selects the fastest one.
Querying the server list is a HTTP GET request on that URL. The
response is a JSON document that contains server infos, server addresses
as URLs and an approximate location.
It can also contain a legacy server list which is a list of bare IP
addresses similar to the functionality the old master servers provided
via UDP. This allows us to backtrack on the larger update if it won't
work out.
Lost functionality
==================
(also known as user-visible changes)
Since the client doesn't ping each server in the list anymore, it has no
way of knowing its latency to the servers.
This is alleviated a bit by providing an approximate location for each
server (continent) so the client only has to know its own location for
approximating pings.
3811: Add Intel as vendor to the block list on windows r=def- a=Jupeyy
I also added, that the warning doesnt require to be displayed, as it currently won't help anyway to update the driver.
Should set all Intel users to OGL 2.0 default, they can ofc still manually change the setting as they want

3535: Fix a possible race in load code r=def- a=heinrich5991
Previously, a save could possibly be loaded twice given enough latency
discrepancy between servers. The server only verified that it deleted
*some* save with the given password, not *the* save it is trying to
load. This is fixed by also checking the SaveID column that is random
and globally unique (except for the old NULLs). Since users can't create
new saves with NULL SaveID, these pose no problem.
Also change the default UUID for saves without save ID to something
nonzero, so we can't accidentally hit it due to a bug.

Currently this replaces `str_copy` text input and clipboard paste in chat. Many places may need the same treatments, like steam names.

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.

This came from a long discussion comparing PCG-* against xoroshiro*. Do
not generate integers without bias because it doesn't affect us very
much and it is easier to reimplement with modulo.
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.
