* gpg-agent.c (handle_signal): Reload the trustlist on SIGHUP.

Browse Source 
(start_connection_thread): Hack to simulate a ticker.
* trustlist.c (agent_trustlist_housekeeping)
(agent_reload_trustlist): New.  Protected all global functions
here with a simple counter which is sufficient for Pth.

* fingerprint.c (gpgsm_get_key_algo_info): New.
* sign.c (gpgsm_sign): Don't assume RSA in the status line.
* keylist.c (list_cert_colon): Really print the algorithm and key
length.
(list_cert_raw, list_cert_std): Ditto.
(list_cert_colon): Reorganized to be able to tell whether a root
certificate is trusted.
