* protect-tool.c: New option --canonical.

(show_file): Implement it.

* keyformat.txt: Define the created-at attribute for keys.

* ccid-driver.c: Replaced macro DEBUG_T1 by a new debug level.
(parse_ccid_descriptor): Mark SCR335 firmware version 5.18 good.
(ccid_transceive): Arghhh.  The seqno is another bit in the
R-block than in the I block, this was wrong at one place.

* scdaemon.c: New options --debug-ccid-driver and
--debug-disable-ticker.

* app-openpgp.c (do_genkey, do_writekey): Factored code to check
for existing key out into ..
(does_key_exist): .. New function.

* gpg-connect-agent.c (add_definq, show_definq, clear_definq)
