This improves commit ec6a6779236a89d4784a6bb7de0def9cc0f9e8a4 to avoid
looping over all keypairinfos.  This way scdaemon does not need to
compute all the keypairinfos for all keys of a card.  This patch is
possible due the enhanced READKEY command in scdaemon.

We already have $AUTHKEYID to locate the keyref of the key to be used

--

The old algorithm limited the length of a bucket chain by purging the
last 50% or the entries.  Thus the first domains entered into the
cache were never purged.  The new algorithm is a bit better: It also
limits the chain length on overflow to 50% but tries to keep the
entries indicating that a WKD is available in the cache.  If there is
still space to keep more, those which clearly do not support WKD are
also kept.

Having the version of the yubikey is important to select which other

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

This prepares the support for OpenPGP v5 keys.  The new version 2 blob
format is needed for the longer fingerprints and we also use this
opportunity to prepare for storing the keygrip in the blob for faster
lookup by keygrip.  Right now this is not yet functional.
