2999d301ad Add: [Network] Validate the client name when receiving one from the server
This so names from other clients are known valid in the client as well, instead allowing some compromised/bad server to potentially crash clients upon certain expectations.

ce6a744278 Doc: server name doesn't need to be advertised to be valid
Strictly seen the comment is true, as it says 'e.g.', but it is
misleading. The server name is just that: the name of the server
as configured. No need to mention advertising.

cd757d53ca Codechange: remove always-empty "address" from NetworkContentSocketHandler
When ever you saw this debug lines (which you never should), they
showed an empty address. It is also not very useful to have, as it
always points to a known server anyway.

31897eaa7d Codechange: split ParseConnectionString into two functions

05612d60ae Remove: "language" field from server/client
The original idea was that people could find a server they could
talk in their native language on. This isn't really used in that
way. There are several reasons for removing this:

- the client also sends his "language" to the server, but nothing
  is doing anything with this.
- flags are a bad way to represent languages, and over the years
  we had several (rightfully) complaints about this.
- most servers have their language set to "All", and prefix the
  servername with the language it is about. This is a much more
  efficient way to do the same.

All in all, this feature should go back to the drawing board.
Maybe it could work in another form, but this form is not it.

f4bd3fff5e Remove: "map_name" from server announcements / listing
The idea back in the days was nice, but it never resulted in
anything useful. Most servers either read "(loaded game)" or
"Random Map", neither being useful. It was meant for heightmaps,
so you could find a server that was using a specific one .. but
there are many things wrong with that idea. Mostly, servers tend
to save and load savegames from time to time, after which the
original heightmap used was lost.

All in all, removing map_name all together is just better.

837994034d Fix: Sizing of Multiplayer server list incorrect when GUI zoom doesn't match Font zoom.
The server information panel was scaled by GUI scale, which could result in a panel that is longer than the server list. This height difference is then maintained when the window is resized to fill the screen.
Instead, specify the minimum size by number of text lines and (summed total) padding.

825867f2c5 Fix: [Network] State conditions for sending client info/quit packets (#8959)
Use status >= STATUS_AUTHORIZED as the state criteria for all cases
where updates about other clients are sent.
This avoids the case where a client is informed that another client
has joined but not informed when it later quits, resulting in
stale entries in the client list window.

970fedd78c Add: make modal windows update more smooth
Basically, modal windows had their own thread-locking for what
drawing was possible. This is a bit nonsense now we have a
game-thread. And it makes much more sense to do things like
NewGRFScan and GenerateWorld in the game-thread, and not in a
thread next to the game-thread.

This commit changes that: it removes the threads for NewGRFScan
and GenerateWorld, and just runs the code in the game-thread.
On regular intervals it allows the draw-thread to do a tick,
which gives a much smoother look and feel.

It does slow down NewGRFScan and GenerateWorld ever so slightly
as it spends more time on drawing. But the slowdown is not
measureable on my machines (with 700+ NewGRFs / 4kx4k map and
a Debug build).

Running without a game-thread means NewGRFScan and GenerateWorld
are now blocking.

0243ae4654 Fix #8799: NGameAllowedSorter() is not imposing strict weak ordering relation (#8801)
In other words, it should only (!) return true if A comes for B.
This promise was broken for the situation where two values are
identical. It would return true in these cases too. This is of
course not possible: if two values are identical, neither come
before the other. As such, the sorter was not imposing strict
weak ordering relations.

libstdc++ handled this scenario just fine, but libc++ crashes
badly on this, as it allowed comparing of [begin, end] instead
of [begin, end).
libc++ considered this not a bug (and by specs, they are correct;
just this way of crashing is of course a bit harsh):

3677418225 Fix: [Network] also count the person downloading the map in the queue
Strictly seen, there are "N" people -waiting- in front of you
in the queue, but it is nicer to show "N + 1" for the person that
is currently downloading the map. Avoids it showing:
"0 clients in front of you". That just feels a bit off.

d068d61f3c Fix bddfcaef: don't tell twice that a client left because of a timeout etc (#8746)
SendError() notifies all clients of the disconnect. This calls
CloseConnection() at the end, which also notified the clients
of the disconnect. Really no need to do it twice.

The status NETWORK_RECV_STATUS_SERVER_ERROR is only set by
SendError(), so in case that is the status, don't let
ClientConnection() send another notification.

7fbf705c41 Fix 2db88953: default Network Server List sorter put compatible servers in wrong order (#8626)
If a server is compatible, it falls back to sorting by clients.
This used to be in reverse, so full servers are on top. With
the codechange commit, this was removed by accident, and as
such empty servers were on top. This is silly.

62cdadb582 Change: move "give money" from client-list to company window
This is a much better location for this button, as you send
money from one company to another company, not from player
to player.

This is based on work done by JGRPP in:
f820543391
and surrounding commits, which took the work from estys:
https://www.tt-forums.net/viewtopic.php?p=1183311#p1183311

We did modify it to fix several bugs and clean up the code while
here anyway.

The callback was removed, as it meant a modified client could
prevent anyone from seeing money was transfered. The message
is now generated in the command itself, making that impossible.
