encode.c, getkey.c, revoke.c: The current flags for different levels of
PGP-ness are massively complex. This is step one in simplifying them.
No functional change yet, just use a macro to check for compliance level.
pkclist.c (algo_available), revoke.c (gen_revoke): Add --pgp8 mode. This
is basically identical to --pgp7 in all ways except that signing subkeys,
v4 data sigs (including expiration), and SK comments are allowed.
* getkey.c (finish_lookup): Comment.
cipher when importing a secret key.
* keylist.c (list_keyblock_print): Show a '#' for a secret-parts-missing
key.
* parse_packet.c (parse_key): Some comments.
* revoke.c (gen_revoke): Remove some debugging code.
* trustdb.c (verify_own_keys): Make trusted-key a non-deprecated option
again.
sensitive revkeys along with the revocation sig itself.
* keyserver.c (parse_keyserver_options): Simpler implementation that can
skip one pass over the options.
as an argument to an addrevoker command. This sets the 0x40 sensitive
revoker flag.
* revoke.c (gen_desig_revoke): When generating a designated revocation,
include the direct key sig that contains the designated revoker subpacket.
This allows sensitive designated revocation subpackets to be exported.
Also indicate which revokers are sensitive in the first place.
