Build and run Last Chaos Server on Debian 12.5 amd64

Last Chaos Server based on the 2015/2018 code base and
patched to build and run on the latest versions of Linux.

This source code does not require manual compilation of libraries
and uses native libraries of modern distributions. You just need to
install the dependeces libraries and headers in your distribution.

Compilation and run of the server were tested on Debian 12.5 amd64
and Gentoo (Protage 2024) distributions using the GCC-12 and Clang-16
compilers.

Lags in the game due to the fact that the virtual disk is located on an external USB HDD.
The weakness of the Virtualbox video adapter is also strongly affected.
The cursor is displayed as a square, too, because of the virtual machine.
