lib, ipcpd, irmd: Wrap pthread unlocks for cleanup

This add an ouroboros/pthread.h header that wraps the
pthread_..._unlock() functions for cleanup using
pthread_cleanup_push() as this casting is not safe (and there were
definitely bad casts in the code). The close() function is now also
wrapped for cleanup in ouroboros/sockets.h.
This allows enabling more compiler checks.
