I can be assumed that configured LDAP servers are somehow curated and
not affected by rogue key signatures as the HKP servers are.  Thus we
don't clean the key anymore so that key certifications are kept even
if the public key has not yet been imported.

Initial tests with this option are not very promising.  Importing
about 3000 real world keys with --use-keyboxd and full logging took:

   real    33m31.724s
   user    19m54.265s
   sys     2m49.662s

With bulk-import this saves a mere 12%:

   user    19m3.391s
   sys     2m46.728s

This is is the second part to support the new Key Block subpacket.
The idea is that after having received a signed mail, it is instantly
possible to reply encrypted - without the need for any centralized
infrastructure.

There is one case where this does not work: A signed mail is received
using a specified signer ID (e.g. using gpg --sender option) and the
key block with only that user ID is thus imported.  The next time a
mail is received using the same key but with a different user ID; the
signatures checks out using the key imported the last time.  However,
the new user id is not imported.  Now when trying to reply to that
last mail, no key will be found.  We need to see whether we can update
a key in such a case.

gpg: Set a limit of 5 to the number of keys imported from the WKD.
* g10/import.c (import): Limit the number of considered keys to 5.
(import_one): Return the first fingerprint in case of WKD.
--

The Web Key Directory should carry only one key.  However, some
providers like to put old or expired keys also into the WKD.  I don't
thunk that this is a good idea but I heard claims that this is needed
for them to migrate existing key data bases.

This patch puts a limit on 5 on it (we had none right now) and also
fixes the issue that gpg could not work immediately with the requested
key because the code uses the fingerprint of the key to use the
imported key.  Now the first key is used.  On a second try (w/o
accessing the WKD) the regular key selection mechanism would be in
effect.  I think this is the most conservative approach.  Let's see
whether it helps.

The PGP desktops exported secret keys are really stupid.  And they

  [...]  Implementations SHOULD include self-signatures on any user
  IDs and subkeys, as this allows for a complete public key to be
  automatically extracted from the transferable secret key.
  Implementations MAY choose to omit the self-signatures, especially
  if a transferable public key accompanies the transferable secret
  key.

Now if they would only put the public key before the secret
key. Anyway we now have a workaround for that ugliness.

When importing an invalid secret key ring for example without key
binding signatures or no UIDs, gpg used to let gpg-agent store the
secret keys anyway.  This is clearly a bug because the diagnostics
before claimed that for example the subkeys have been skipped.
Importing the secret key parameters then anyway is surprising in
particular because a gpg -k does not show the key.  After importing
the public key the secret keys suddenly showed up.

This changes the behaviour of

to me more consistent but is not a solution to the actual bug.

Caution: The ecc.scm test now fails because two of the sample keys

This prepares the support for OpenPGP v5 keys.  The new version 2 blob

make valgrind happy.  More serious was that we always passed
MAX_FINGERPRINT_LEN but we will need to support 20 and 32 octet
fingerprints and MAX_FINGERPRINT_LEN would be too large for a v4.

common: Prepare for parsing mail sub-addresses.
* common/mbox-util.c (mailbox_from_userid): Add arg subaddress and
implement.  Change all callers to pass false for it.

* common/t-mbox-util.c (run_mbox_no_sub_test): New.
(run_filter): Add arg no_sub.
(main): Call new test and add option --no-sub.
--

Some stats: In the about 5300000 keys on the SKS servers we found 3055
unique mailboxes with a '+' in it.  After removing leading and
trailing '+' as well as multiple '+' (e.g. "c++" or "foo+bar+baz")
2697 were left which seem to be valid sub-addresses.

To filter mailboxes out from a line delimited list with
user-ids (e.g. an SQL output), the command

   t-mbox-util --verbose --filter

can be used; to output w/o sub-addresses add --no-sub.

(get_pubkey_byname): Set it.
(only_expired_enc_subkeys): New.

A little drawback of that code is that if the WKD has no update for an
expired key each access of the key will trigger a WKD lookup (unless
cached by the dirmngr).  To avoid this we need to record the last time
we have checked for an update but that would in turn require that we
update the keyring for each check.  We defer this until we have a
better key database which allows for fast updates of meta data.

Testing the code is currently a bit cumbersome because it requires to
update a key in the WKD several times.  Eventually we we need a
network emulation layer to provide sample data for the regression
tests.

gpg: Print revocation reason for "rvs" records.
* g10/import.c (get_revocation_reason): New.

--

Note that this function extends the "rvs" field signature-class (field
11) with the revocation reason.  GPGME does not yet parse this but it
can be expected that the comma delimiter does not break other parsers.

A new field is added to the "rvs" (and in future also the "rev")
record to carry a record specific comment.  Hopefully all parsers
meanwhile learned the lesson from other new fields and don't bail out
on more fields than they know about.
