"openpgp" which is classic+trustsigs, "classic" which is classic only, and
"always" which is the same as the current option --always-trust (which
still works). Default is "openpgp".
* trustdb.c (validate_one_keyblock): Use "openpgp" trust model to enable
trust sigs.
* gpgv.c (main), mainproc.c (check_sig_and_print), pkclist.c (do_we_trust,
do_we_trust_pre, check_signatures_trust): Use new --trust-model option in
place of --always-trust.
* keylist.c (print_capabilities): Properly indicate per-key capabilities
of sign&encrypt primary keys that have secret-parts-missing (i.e. no
capabilities at all)
* mainproc.c (symkey_decrypt_sesskey): Fix compiler warning.
printing the list of keys a message was encrypted to. This would make gpg
give a non-zero exit code even for completely valid messages if the
message was encrypted to more than one key that the user owned.
decryption failed error if a MDC does not verify. Warn if a MDC is not
present (can disable via --no-mdc-warning).
* exec.c (exec_write), g10.c (main), keyserver.c (keyserver_spawn): Use
new DISABLE_KEYSERVER_PATH rather than FIXED_EXEC_PATH.
FIXED_PHOTO_VIEWER and DISABLE_PHOTO_VIEWER.
* mainproc.c (check_sig_and_print): Use --show-photos to show photos when
verifying a sig made by a key with a photo.
* keyserver.c (parse_keyserver_uri): Properly parse a URI with no :port
section and an empty file path, but with a terminating '/'.
(keyserver_work): Honor DISABLE_KEYSERVER_HELPERS.
* hkp.c (hkp_ask_import): Display keyserver URI as a URI, but only if
verbose.
* exec.c, g10.c: USE_EXEC_PATH -> FIXED_EXEC_PATH
use the original keyserver URI for cosmetics rather than trying to
recreate it when needed.
* mainproc.c (check_sig_and_print): Properly disregard expired uids.
Make sure that the first uid listed is a real uid and not an attribute
(attributes should only be listed in the "aka" section). When there are
no valid textual userids, try for an invalid textual userid before using
any attribute uid.
