2023-07-05tcp_server: minor refactoringEgor Tensin
2023-07-05tcp_server: close client connectionsEgor Tensin
I kinda forgot that I'm supposed to clean up client connections, and they immediately blew up in my face.

2023-07-05tcp_server: keep track of client threadsEgor Tensin
This is a major change, obviously; brought to me by Valgrind, which noticed that we don't actually clean up after cimple-client threads. For a more thorough explanation, please see the added comment in tcp_server.c.

Thanks, Valgrind! As a note: if I think that Valgrind reports a false positive, chances are, it's not.

Also, use cmake's configure_file to build string constants in.

2023-06-30use __WNOTHREAD w/ waitpidEgor Tensin
I learned about this flag on my previous job; basically, it should be enabled by default IMO, so that the thread doesn't receive signals from other threads' children. Here, it doesn't matter too much, since we're waiting for a specific child. However, if we were to use waitpid(-1, ...), it would be essential to use this flag. Still, even here, it's good to have this on.

2023-06-13use signalfd to stop on SIGTERMEgor Tensin
Is this an overkill? I don't know. The thing is, correctly intercepting SIGTERM (also SIGINT, etc.) is incredibly tricky. For example, before this commit, my I/O loops in server.c and worker.c were inherently racy. This was immediately obvious if you tried to run the tests. The tests (especially the Valgrind flavour) would run a worker, wait until it prints a "Waiting for a new command" line, and try to kill it using SIGTERM. The problem is, the global_stop_flag check could have already been executed by the worker, and it would hang forever in recv(). The solution seems to be to use signalfd and select()/poll(). I've never used either before, but it seems to work well enough - at least the very same tests pass and don't hang now.

Modifying cmd_dispatcher fields like that make it inherently unsafe to call cmd_dispatcher_handle_conn concurrently.
