* g10/gpgv.c, g10/trustdb.c (read_trust_options): Add min_cert_level
* g10/trustdb.c (check_trustdb_stale): Request a rebuild if
pending_check_trustdb is true (set when we detect a trustdb
parameter has changed).
* g10/keylist.c (public_key_list): Use 'l' in the "tru" with-colons
listing for min_cert_level not matching.
* g10/tdbio.c (tdbio_update_version_record, create_version_record,
tdbio_db_matches_options, tdbio_dump_record, tdbio_read_record,
tdbio_write_record): Add a byte for min_cert_level in the tdbio
version record.
The functions tdbio_read_record and tdbio_write_record control the
actual on-disk format. Thus there is no need to keep reserved fields
in the internal data structure.
* g10/tdbio.h (struct trust_record): Remove reserved fields.
getkey.c, keydb.c, openfile.c, plaintext.c, status.c, gpgv.c, keygen.c,
options.h, sig-check.c, tdbio.h, encode.c, mainproc.c, parse-packet.c,
signal.c, textfilter.c: Edit all preprocessor instructions to remove
whitespace before the '#'. This is not required by C89, but there are some
compilers out there that don't like it.
mode.
* tdbio.h, tdbio.c (tdbio_read_model): New function to return the trust
model used in a given trustdb.
* options.h, g10.c (main), trustdb.c (init_trustdb, check_trustdb,
update_trustdb): Use tdbio_read_model to implement an "auto" trust model
which is set via the trustdb.
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.
model in the trustdb version record. (tdbio_update_version_record): New
function to update version record values during a trustdb check or update.
(tdbio_dump_record): Show trust model in dump.
* trustdb.c (validate_keys): Call tdbio_update_version_record on success
so that the correct options are stored in the trustdb.
* options.h: rearrange trust models so that CLASSIC is 0 and OPENPGP is 1.
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).
