In contrast to a search via keyserver_import_ntds the older
keyserver_import_name used a full match of the provided name despite
that it is only called with an addr-spec (mbox). Due to the mode the
pattern send to dirmngr was prefixed with a '=' and thus dirmngr used
an exact search;. This did only work for provided user ids like
"foo@example.org" but not for "<foo@example.org>" or
"Foo <foo@xample.org>". The old code dates back to 2010.

--
This change makes it easy to start working with gnupg: Just insert the
smartcard or token provided to you and the first time you sign a
message the public key associated with the current card will be
imported and everything is set without any configuration.
This works only with an LDAP directory because it can be expected that
the public key has been put into the LDAP during card personalization.
Of course an LDAP server needs to be configured; in a Windows AD
domain this can be a mere "keyserver ldap:///" in dirmngr.conf. Other
configured keyservers are ignored.
Requirements for the card driver: The $SIGNKEYID attribute must exists
and a query for the KEY-FPR attribute needs to return the OpenPGP
fingerprint for that key. This is currently supported for OpenPGP
cards and certain PKCS#15 cards.

PKA (Public Key Association) was a DNS based key discovery method
which looked up fingerprint by mail addresses in the DNS. This goes
back to the conference where DKIM was suggested to show that we
already had a better method for this available with PGP/MIME. PKA was
was later superseded by an experimental DANE method and is today not
anymore relevant. It is anyway doubtful whether PKA was ever widely
used.

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.

This generic caching module is better than the ad-hoc code we used in
getkey.c. More cleanup in getkey is still required but it is a
start. There is also a small performance increase with the new cache:
With a large keyring and --list-sigs I get these numbers:
| | before | after |
|------+------------+------------|
| real | 14m1.028s | 12m16.186s |
| user | 2m18.484s | 1m36.040s |
| sys | 11m42.420s | 10m40.044s |
Note the speedup in the user time which is due to the improved cache
algorithm. This is obvious, because the old cache was just a long
linked list; the new cache are two hash tables.

--
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.
