* cardglue.c (learn_status_cb): Release values before assignment

Browse Source 
so that it can be used by getattr to update the structure.
(agent_scd_getattr): New.

* keylist.c (print_pubkey_info): Add FP arg for optional printing
to a stream.  Changed all callers.

* keylist.c (print_pubkey_info): Add FP arg for optional printing

2003-10-01 Werner Koch <wk@gnupg.org>
* app-common.h, app-openpgp.c, iso7816.c, iso7816.h, apdu.c
* apdu.h, ccid-driver.c, ccid-driver.h, card-util.c: Updated
from current GnuPG 1.9. Changes over there are:
* card-util.c: Tweaked to use this source also under 1.3.
(card_edit): New command "forcesig".
* card-util.c (print_name, print_isoname): Use 0 and not LF fro
the max_n arg of tty_print_utf8_string2.
* card-util.c (change_pin): Simplified. We now have only a PIN
and an Admin PIN.
* ccid-driver.c: Detect GnuPG 1.3 and include appropriate files.
* apdu.c: Ditto.
* app-openpgp.c: Ditto.
* iso7816.c: Ditto.
(generate_keypair): Renamed to ..
(do_generate_keypair): .. this.
* app-common.h [GNUPG_MAJOR_VERSION]: New.
* iso7816.h [GNUPG_MAJOR_VERSION]: Include cardglue.h
* app-openpgp.c (do_change_pin): Make sure CVH1 and CHV2 are
always synced.
(verify_chv2, verify_chv3): New. Factored out common code.
(do_setattr, do_sign, do_auth, do_decipher): Change the names of
the prompts to match that we have only 2 different PINs.
(app_select_openpgp): Check whether the card enforced CHV1.
(convert_sig_counter_value): New. Factor out code from
get_sig_counter.
* Makefile.am (card_support_source): Depend on new AM conditional
to get the ifdef ENABLE_CARD_SUPPORT off the way from source
copied files.
(update-source-from-gnupg-2): Maintainer helper.
2003-10-01 David Shaw <dshaw@jabberwocky.com>
* g10.c (main): Add --no-groups to zero --group list.
