Historically, we've used security_context_t for variables passed
to libselinux APIs. But almost 7 years ago, libselinux developers
admitted in their API that in fact, it's just a 'char *' type
[1]. Ever since then the APIs accept 'char *' instead, but they
kept the old alias just for API stability. Well, not anymore [2].
