* trustdb.h, trustdb.c (trust_letter): Make static. (get_ownertrust_info,
get_validity_info): Don't mask the trust level twice.
* trustdb.h, gpgv.c, trustdb.c (get_validity, get_validity_info),
keylist.c (list_keyblock_colon), keyedit.c (show_key_with_all_names_colon,
menu_revuid): Pass a user ID in rather than a namehash, so we only have to
do the hashing in one place.
* packet.h, pkclist.c (build_pk_list), free-packet.c
(release_public_key_parts): Remove unused namehash element for public
keys.
trustdb.c (update_validity): Store temporary full & marginal counts in the
trustdb. (clear_validity, get_validity_counts): Return and clear temp
counts. (store_validation_status): Keep track of which keyids have been
stored. (validate_one_keyblock, validate_key_list): Use per-uid copies of
the full & marginal counts so they can be recalled for multiple levels.
(validate_keys): Only use unused keys for each new round.
(reset_unconnected_keys): Rename to reset_trust_records, and only skip
specifically excluded records.
Minimal isn't always best.
* sign.c (update_keysig_packet): Use the current time rather then a
modification of the original signature time. Make sure that this doesn't
cause a time warp.
* keygen.c (keygen_add_key_expire): Properly handle a key expiration date
in the past (use a duration of 0).
* keyedit.c (menu_expire): Use update_keysig_packet so any sig subpackets
are maintained during the update.
* build-packet.c (build_sig_subpkt): Mark sig expired or unexpired when
the sig expiration subpacket is added. (build_sig_subpkt_from_sig): Handle
making an expiration subpacket from a sig that has already expired (use a
duration of 0).
* packet.h, sign.c (update_keysig_packet), keyedit.c
(menu_set_primary_uid, menu_set_preferences): Add ability to issue 0x18
subkey binding sigs to update_keysig_packet and change all callers.
like "fully trusted", "marginally trusted", etc. (get_min_ownertrust):
New. Return minimum ownertrust. (update_min_ownertrust): New. Set
minimum ownertrust. (check_regexp): New. Check a regular epression
against a user ID. (ask_ownertrust): Allow specifying a minimum value.
(get_ownertrust_info): Follow the minimum ownertrust when returning a
letter. (clear_validity): Remove minimum ownertrust when a key becomes
invalid. (release_key_items): Release regexp along with the rest of the
info. (validate_one_keyblock, validate_keys): Build a trust sig chain
while validating. Call check_regexp for regexps. Use the minimum
ownertrust if the user does not specify a genuine ownertrust.
* pkclist.c (do_edit_ownertrust): Only allow user to select a trust level
greater than the minimum value.
* parse-packet.c (can_handle_critical): Can handle critical trust and
regexp subpackets.
* trustdb.h, trustdb.c (clear_ownertrusts), delkey.c (do_delete_key),
import.c (import_one): Rename clear_ownertrust to clear_ownertrusts and
have it clear the min_ownertrust value as well.
* keylist.c (list_keyblock_print): Indent uid to match pub and sig.
menu_addrevoker), keylist.c (list_keyblock_print, print_fingerprint): Show
"T" or the trust depth for trust signatures, and add spaces to some
strings to make room for it.
* packet.h, parse-packet.c (dump_sig_subpkt, parse_one_sig_subpkt,
parse_signature): Parse trust signature values.
* tdbio.h, tdbio.c (tdbio_read_record, tdbio_write_record): Reserve a byte
for the minimum ownertrust value (for use with trust signatures).
that fact in the capabilities, and only primary signing keys can certify
other keys.
* packet.h, parse_packet.c (parse_key): Add is_primary flag for public
keys (it already exists for secret keys).
