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.

The Web Key Directory should carry only one key. However, some

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

out (section 11.2):
[...] 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
GnuPG-bug-id: 4392
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
don't have binding signatures.

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.
