Subject: Replace CLI arguments with config-file parser and add integration
 tests

Introduce a reusable key=value config parser (config.h/c) and convert
all three programs to read their settings from config files instead of
positional command-line arguments.  Add example config files in config/
and 6 CTest integration tests covering None/Basic256Sha256/Aes128 with
anonymous and user authentication.  Remove the now-obsolete launch.sh.
