The current NETMSG_PING and NETMSG_PING_REPLY messages suffer from the
fact that you cannot know whether a given NETMSG_PING_REPLY is from your
NETMSG_PING.
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.
3492: Support F-Client and replace non-extended extension messages r=Learath2 a=heinrich5991
This continues what #3439 started, and also replaces non-extended messages that are DDRace extensions with extended messages. The DDNet server still sends the old message to old clients and the DDNet client still understands the old messages.
Supersedes #3439.

3561: Fix input message position in teehistorian files r=heinrich5991 a=Zwelf
Previously the message was recorded when incoming. But the time when the input should apply wasn't recorded. Now inputs are recorded right before they get applied in the game world.
And record exact tick where load/save result is returned.

The PLAYERFLAG_AIM can now be set directly on DDNet servers via the 0.7
bridge and will be sent to clients identifying themselves as DDNet
clients.
Add a new extended message that mirror the old `Sv_TeamsState`.
3139: Use NUM_DUMMYS for dummy array length r=def- a=ChillerDragon
Should make code more readable by explaining that the array is used for dummy. Also makes modders life easier if there is a need to scale up dummy count.
I left out two places that do not include client.h
3be8a592e5/src/game/client/prediction/gameworld.h (L92)3be8a592e5/src/game/gamecore.h (L212)
Moving the enum to protocol.h for example is probably not nice.

To be friendly to other implementors of the format, the CRC field is now
zeroed out instead of completely gone.
Drop support for v2 and v3 of the ghost format, the ghost files should
have been automatically converted by the client already.
