Fix: [CMake] openttd.32.bmp wasn't installed but used by SDL (#9772)

This file is used to set the SDL application icon, but it was no longer
installed since the switch to CMake.

Change: [OSX] Allow touchbar usage on all supported OS versions.

Touchbar support was introduced in 10.12.2. There's no need to limit
support to 10.15+, as the convenience class NSButtonTouchBarItem is
easily replicated.

Doc: use only double quotes for cmake command line example in COMPILING.md (#9758)

While powershell happily accepts single quotes, it's not the case for cmd.

Fix #9756: Network command unpack proc was not generated in all cases.

The case where the callback proc takes all command results but not any of
the command parameters was not handled properly.

Change: [Admin] Bump admin port protocol due to command changes.

docs/admin_network.md promised that information in an admin packet
is never removed. It does allow the possibility of using a new packet type
for changed data in combination with a bump of the admin port version.

As the recent command handling changes modified the contents of
ADMIN_PACKET_SERVER_CMD_LOGGING, do exactly that.

Codechange: Don't generate CommandPacket unpack functions for invalid cmd/callback combinations.

If the arguments of the callback proc don't match with the command parameters,
we can't do the proper command execution anyway. As such, don't even generate
an unpack function in the first place, saving a bit of unnecessary code bloat.

Validate on receive that the cmd/callback combination is supported, rejecting
clients that try to send invalid values.

Codechange: Add DoCommand::Post specialization for commands that take no TileIndex.

This adds a new Post overloads that still take a TileIndex which
is used to place any error windows or text effects.

Codechange: Template DoCommandP to automagically reflect the parameters of the command proc.

When finished, this will allow each command handler to take individually
different parameters, obliviating the need for bit-packing.

Codechange: Template DoCommand to automagically reflect the parameters of the command proc.

When finished, this will allow each command handler to take individually
different parameters, obliviating the need for bit-packing.

Change: [Network] Transfer command data as serialized byte stream without fixed structure.

The data will be transmitted as the length followed by the serialized data. This allows the command
data to be different for every command type in the future.

Codechange: Make TileIndex a "strong" typedef to give it a distinct type.

This is accomplished by changing it to a single member struct with the
appropriate operator overloads to make it all work with not too much
source modifications.

Codechange: Let the compile generate the master command table out of templated command traits.

This is using a non-intrusive type-traits like templated system, which
allows compile-time validation that the command table and the command
enum match up.

Fix #9730: [Network] connections can use an invalid socket due to a race condition

A race condition happens when an IPv6 connection takes more than
250ms to report an error, but does return before the IPv4 connection
is established.
In result, an invalid socket might be used for that connection.

Codechange: ensure OnConnect() always gets called with a valid socket (#9729)

This should already be the case, but now assert()s will tell us
if this isn't.

Codechange: Remove CargoSpec::multipliertowngrowth which is unused (#9701)

This is set by cargo property 19.
This property is only implemented in TTDPatch.

Change: [Emscripten] update to 2.0.34 and use Release over RelWithDebInfo (#9696)

It turns out that having "-g" in the compile-statement causes
Emscripten to pick -g3, which makes for very big binaries. This
is very likely not your intention when building Emscripten, as
smaller really is better.

For comparison, with RelWithDebInfo the binary is ~80MB. With
Release it is ~7.4MB.

Fix: don't complain when the sprite font is missing glyphs. (#9692)

Silently auto-pick a suitable font.
