functions to return data about an image.
* packet.h, parse-packet.c (make_attribute_uidname,
parse_attribute_subpkts, parse_attribute), photoid.h, photoid.c
(show_photos): Handle multiple images in a single attribute packet.
* main.h, misc.c (pct_expando), sign.c (mk_notation_and_policy), photoid.c
(show_photos): Simpler expando code that does not require using
compile-time string sizes. Call image_type_to_string to get image strings
(i.e. "jpg", "image/jpeg"). Change all callers.
* keyedit.c (menu_showphoto), keylist.c (list_keyblock_print): Allow
viewing multiple images within a single attribute packet.
* gpgv.c: Various stubs for link happiness.
that has been revoked by designated revoker, but the designated revoker is
not present to verify the revocation (whew!). This applies to all ways to
get a key into the system: --import --recv-keys, and --search-keys. If
auto-key-retrieve is set, try and retrieve the revocation key.
Also, auto-key-retrieve is now a keyserver-option.
used with the agent. Changed all callers.
(agent_get_passphrase): Likewise and send it to the agent
* seckey-cert.c (do_check): New arg tryagain_text.
(check_secret_key): Pass the string to do_check.
* keygen.c (ask_passphrase): Set the error text is required.
* keyedit.c (change_passphrase): Ditto.
* passphrase.c (agent_open): Disable opt.use_agent in case of a
problem with the agent.
(agent_get_passphrase): Ditto.
(passphrase_clear_cache): Ditto.
Remove get_temp_dir (it's in exec.c now)
Allow --delete-key (now --delete-keys, though --delete-key still works) to
delete multiple keys in one go. This applies to
--delete-secret-key(s) and --delete-secret-and-public-key(s) as well
