The idea here is to unify our use of URLS or colon delimited ldap
keyserver specification. The requirement for percent escaping, for
example the bindname in an URLs, is cumbersome and prone to errors.
This we allow our classic colon delimited format as an alternative.
That format makes it also easy to specify flags to tell dirmngr
whether to use starttls or ldap-over-tls. The code is nearly 100%
compatible to existing specification. There is one ambiguity if the
hostname for CRL/X509 searches is just "ldap"; this can be solved by
prefixing it with "ldap:" (already implemented in gpgsm).

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.

* dirmngr/ks-engine-ldap.c (extract_attributes): Do not store the
pgpSignerID.
* g10/call-dirmngr.c (ks_put_inq_cb): Do not emit sig records.
--
The pgpSignerID has no use in the LDAP and thus don't store it.
David's idea back in 2004 was
/* This bit is really for the benefit of people who
store their keys in LDAP servers. It makes it easy
to do queries for things like "all keys signed by
Isabella". */
See-commit: 3ddd4410ae
I consider this dangerous because such a query is not able to validate
the signature, does not get revocation signatures, and also has no
information about the validity of the signatures. Further many keys
are spammed tehse days with faked signatures and it does not make
sense to blow up the LDAP with such garbage.

The old code simply did not use https for downloading of CRLS.
Instead it rewrote https to http under the assumption that the CRL
service was also available without encryption. Note that a CRL is
self-standing and thus it does not need to have extra authenticity as
provided by TLS. These days we should not use any unencrypted content
and thus this patch.
Be aware that cacert.org give a https CRL DP but that currently
redirects to to http! This is a downgrade attack which we detect and
don't allow. The outcome is that it is right now not possible to use
CAcert certificates.

This finalizes the feature to efficiently cache WKD checks. If a
standard WKD query returns no data, we queue a test to be run after
the end of the session (so that we do not delay the calling client).
This check tests whether the server responsible for the queried
address has WKD at all enabled. The test is done by checking whether
the "policy" file exists. We do not check the "submission-address"
file because that is not necessary for the web key operation. The
policy file is now required.

To better cope with round robin pooled A records like keys.gnupg.net
we need to keep some information on unresponsive hosts etc. What we
do now is to resolve the hostnames, remember them and select a random
one. If a host is dead it will be marked and a different one
selected. This is intended to solve the problem of long timeouts due
to unresponsive hosts.
The code is not yet finished but selection works.
The basic network code from http.c is used for finger. This keeps the
network related code at one place and we are able to use the somewhat
matured code form http.c. Unfortunately I had to enhance the http
code for more robustness and probably introduced new bugs.
Test this code using
gpg --fetch-key finger:wk@g10code.com
(I might be the last user of finger ;-)
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
