fix_keyblock() or collapse_uids()) make sure we reprocess the keyblock

* getkey.c (fixup_uidnode): Properly clear flags that don't apply to
us (revoked, expired) so that we can reprocess a uid.
Change all callers. (sign_file, clearsign_file,
sign_symencrypt_file): Calculate one timestamp for the whole
transaction. Different timestamps for each step can leak performance
information.
(write_keybinding): Have the various selfsigs created during key
generation use the timestamp of their parent key. This helps avoid
leaking information about the performance of the machine where the
keys were generated. Noted by Christian Danner.
* configure.ac: Remove GNUPG_DATADIR for non-W32 systems.

* Makefile.am (AM_CPPFLAGS): Define GNUPG_DATADIR.
* openfile.c (copy_options_file): Use log_info and not log_error

and one being DSA2 and encrypting at the same time, if the recipient
preferences give a hash that can work with the DSA2 key, then allow the
DSA1 key to be promoted rather than giving up and using hash_for().
keygen_add_std_prefs, proc_parameter_file): Add --default-keyserver-url to
specify a keyserver URL at key generation time, and "Keyserver:" keyword
for doing the same through a batch file.
(not a copy) of the stub secret key for the secret key we just
generated on the card. (generate_card_subkeypair): Use it here so
that the signing key on the card can use the card to generate the 0x19
backsig on the primary key. Noted by Janko Heilgeist and Jonas Oberg.
This prevents a memory allocation attack with a very large user ID. A
very large packet length could even cause the allocation (a u32) to wrap

* pkclist.c (algo_available): If --enable-dsa2 is set, we're allowed to
truncate hashes to fit DSA keys.
* sign.c (match_dsa_hash): New. Return the best match hash for a given q
size. (do_sign, hash_for, sign_file): When signing with a DSA key, if it
has q==160, assume it is an old DSA key and don't allow truncation unless
--enable-dsa2 is also set. q!=160 always allows truncation since they
must be DSA2 keys. (make_keysig_packet): If the user doesn't specify a
--cert-digest-algo, use match_dsa_hash to pick the best hash for key
signatures.

literal packet filename field is UTF-8 encoded.
* options.h, gpg.c (main): Make sure --set-filename is UTF-8 encoded
and note when filenames are already UTF-8.
* keyedit.c (menu_backsign): Allow backsigning even if the secret
subkey doesn't have a binding signature.
* armor.c (radix64_read): Don't report EOF when reading only a pad (=)
character. The EOF actually starts after the pad.
* gpg.c (main): Make --export, --send-keys, --recv-keys,
--refresh-keys, and --fetch-keys follow their arguments from left to
right. Suggested by Peter Palfrader.

signatures for some backwards compatibility once we start generating DSA2
keys.
* sign.c (do_sign), sig-check.c (do_check): Change all callers.
* sign.c (do_sign): Enforce the 160-bit check for new signatures here

to come out once the standard for DSA2 is firmed up.

* getkey.c (get_pubkey_byname): Use the fingerprint of the key that we
actually fetched. This helps prevent problems where the key that we
fetched doesn't have the same name that we used to fetch it. In the
case of CERT and PKA, this is an actual security requirement as the
URL might point to a key put in by an attacker. By forcing the use of
the fingerprint, we won't use the attacker's key here.

Use it here for the various notation commands.

* options.h, gpg.c (main): Keep track of each keyserver registered so
we can match on them later.
* keyserver-internal.h, keyserver.c (cmp_keyserver_spec,
keyserver_match), gpgv.c: New. Find a keyserver that matches ours and
return its spec.
* getkey.c (get_pubkey_byname): Use it here to get the per-keyserver
options from an earlier keyserver.
(parse_keyserver_options): Moved from here. (parse_keyserver_uri): Use it
here so each keyserver can have some private options in addition to the
main keyserver-options (e.g. per-keyserver auth).

fingerprint we requested.

* pubkey-enc.c (get_session_key): Use it here to handle the case where a
passphrase happens to be correct for a secret key, but yet that key isn't
the anonymous recipient (i.e. the secret key could be decrypted, but not
the session key). This also handles the case where a secret key is
located on a card and a secret key with no passphrase. Note this does not
fix bug 594 (anonymous recipients on smartcard do not work) - it just
prevents the anonymous search from stopping when the card is encountered.

passing the *sk in, so change all callers. This is correct for today,

keygerver_getname): New keyserver_getname function to fetch keys by name.
* getkey.c (get_pubkey_byname): Call it here to enable locating keys by
full mailbox from a keyserver a la PKA. Try PKA first, though, as it is
likely to be faster.
keyserver_fetch): Set a flag to indicate that we're doing a direct URI
fetch so we can differentiate between a keyserver operation and a URI
fetch for protocols like LDAP that can do either.

location. Suggested by Patty A. Hardy.
so keyserver mangled keys with doubled user IDs can be properly

* import.c (parse_import_options), export.c (parse_export_options):
List "xxx-clean" before the longer options so we don't end up with a
partial match on the longer options.
* trustdb.c (clean_uids_from_key): Return proper number of cleaned
user IDs. Don't count user IDs as cleaned unless we actually delete
something.
keygen.c (make_backsig): Did some backsig interop testing with the PGP
folks. All is well, so I'm turning generation of backsigs on for new
keys. Checking for backsigs on verification is still off.
parse_attribute_subpkts): Make a number of warnings verbose items.
These fire on many slightly mangled keys in the field, so the
warning is becoming burdensome.

* keyedit.c (sign_uids): Don't request a signing key to make a
certification.
* keygen.c (do_add_key_flags): Force the certify flag on for all
primary keys, as the spec requires primary keys must be able to
certify (if nothing else, which key is going to issue the user ID
signature?) (print_key_flags): Show certify flag. (ask_key_flags,
ask_algo): Don't allow setting the C flag for subkeys.
* keyid.c (usagestr_from_pk), getkey.c (parse_key_usage): Distinguish
between a sign/certify key and a certify-only key.
* main.h, misc.c (path_access): New. Same as access() but does a PATH
search like execlp.
* keyserver.c (curl_can_handle): Removed. Replaced by...
(curl_cant_handle): We are now relying on curl as the handler of last
resort. This is necessary because PGP LDAP and curl LDAP are apples
and oranges. (keyserver_typemap): Only test for ldap and ldaps.
(keyserver_spawn): If a given handler is unusable (as determined by
path_access()) then try gpgkeys_curl.
to enable the uid walking when signing a key with no uids specified to
sign.
* keylist.c (list_keyblock_print): Fix silly typo. Noted by Greg

export-reset-subkey-passwd.
(do_export_stream): Implement it.
* misc.c (get_libexecdir): New.
* keyserver.c (keyserver_spawn): Use it
when compacting a uid. There is no reason to make an attacker's job
easier - this way they only have a revocation which is useless in
bringing the uid back.
* keydb.h, kbnode.c (undelete_kbnode): Removed. No longer needed.
* import.c (chk_self_sigs): Allow a uid revocation to be enough to
allow importing a particular uid (no self sig needed). This allows
importing compacted uids.
* options.h, import.c (parse_import_options, import_one): Add
import-clean-uids option to automatically compact unusable uids when
importing. Like import-clean-sigs, this may nodify the local keyring.
* trustdb.c (clean_uids_from_key): Only allow selfsigs to be a
candidate for re-inclusion.
import_one): Add import-clean-sigs option to automatically clean a key
when importing. Note that when importing a key that is already on the
local keyring, the clean applies to the merged key - i.e. existing
superceded or invalid signatures are removed.
