fix(steamcmd): add libtinfo.so.5 symlink fix for readline warning

[dgibbs64]

Description

On distros that ship libtinfo.so.6 but not libtinfo.so.5 (Ubuntu 22.04+, Debian 12+), SteamCMD prints the following warning at every run:

WARNING: Failed to load 32-bit libtinfo.so.5 or libncurses.so.5.
  Please install (lib32tinfo5 / ncurses-libs.i686 / equivalent) to enable readline.

lib32tinfo5 does not exist on Ubuntu 22.04+ / Debian 12+ — the package was removed when ncurses transitioned to libtinfo6. This means there is no apt package to install to resolve the warning on modern distros.

Fix

In fix_steamcmd.sh, create a user-space symlink ~/.steam/steamcmd/libtinfo.so.5 -> /lib/i386-linux-gnu/libtinfo.so.6 (or equivalent path) when the .so.5 file is absent. This requires no root access and resolves the warning for all SteamCMD-based game servers.

Testing

Tested on Ubuntu 24.04 LTS — warning no longer appears after the symlink is created.

Pull request overview

Adds a SteamCMD runtime fix for modern distros missing libtinfo.so.5, and introduces TF2 Classified (tf2c) server support which relies on downloading a base appid into a separate support directory.

Changes:

• Add a user-space libtinfo.so.5 -> libtinfo.so.6 symlink workaround in fix_steamcmd.sh.
• Add baseappid download support in the SteamCMD download flow (download base app into supportdir before appid into serverfiles).
• Register new tf2c server (server list entry + default config + config install handling).

The symlink creation can fail if ${HOME}/.steam/steamcmd does not exist yet (fresh install / before SteamCMD has run). Consider mkdir -p "${libtinfo32dir}" before ln, and capture exitcode=$? after ln so fn_fix_msg_end reports failures correctly.

Suggested change

	fn_fix_msg_start
	ln -sf "${libtinfo32so6}" "${libtinfo32so}"
	fn_fix_msg_start
	if [ ! -d "${libtinfo32dir}" ]; then
	mkdir -p "${libtinfo32dir}"
	fi
	ln -sf "${libtinfo32so6}" "${libtinfo32so}"
	exitcode=$?

The guard if [ ! -f ... ] && [ ! -L ... ] skips the fix when libtinfo.so.5 exists as a broken symlink (-L true but target missing). Using an existence check like ! -e (or explicitly handling -L + ! -e) would let the script repair broken links and still avoid overwriting valid files.

Suggested change

	if [ ! -f "${libtinfo32so}" ] && [ ! -L "${libtinfo32so}" ]; then
	if [ ! -e "${libtinfo32so}" ]; then

This new libtinfo fix hard-codes ${HOME}/.steam/steamcmd, but elsewhere in this module SteamCMD artifacts are searched in multiple locations (e.g. ${steamcmddir} and ${HOME}/.local/share/Steam/steamcmd). To ensure the warning is actually resolved in all supported setups, consider applying the symlink fix to the active SteamCMD directory (or iterating through the same candidate directories used for steamclient.so).
