p11-kit commands should provide a means to log PKCS#11 calls

There is an internal variable p11_log_force to log PKCS#11 function calls. It would be useful to expose this through a command-line option, say --log-calls (and possibly --log-file to isolate the output from stderr/stdout).

I did some minor progress on this but I am not quite finished, it is possible to assign it to me (omoris @ Red Hat)
