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.

1.3.6.1.4.1.11591.2.5.1 gpgNtds=1 (auth. with current user)

* dirmngr/ks-engine-ldap.c: Wrap some ldap calls.
--
The former gpgkeys_ldap module has once been ported to dirmngr but
unfortunately the dirmngr_ldap wrapper has not been used so that we
have internal LDAP calls with these problems:
- No usable timeouts.
- On non-Windows platforms a lot of extra libs and possibly even a
second copy of Libgcrypt is pulled in.
- Only one threads runs at a time.
This patch mitigates the last point.

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: 3ddd4410aef928827e1c8d4fb02c1ccd3f8eaea5
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.

but without changing all functions names to gpgrt. Instead we use
wrapper functions which, when building against old Libgpg-error
versions, are implemented in argparse.c using code from the current
libgpg-error. This allows to keep the dependency requirement at
libgpg-error 1.27 to support older distributions. Tested builds
against 1.27 and 1.40-beta.
Note that g13-syshelp does not anymore default to --verbose because
that can now be enabled in /etc/gnupg/g13-syshelp.conf.

With this change a http query will not follow a redirect unless the

the host and port is taken from the Location header and the original
path and query parts are kept.

* dirmngr/dirmngr.c (parse_ldapserver_file): Only print info
for ENOENT.
--
It is very common that there is no ldapserver file. In that
case users are confused by an error printed at dirmngr startup.
* dirmngr/server.c (proc_wkd_get): Tack the raw local address to the
request.
--
We append the raw non-canonicalized local address part to the hash.
Servers who serve the requests from static files will ignore the
parameters and a test with posteo shows that also services using a
database ignore the parameter. The general idea is that service
providers may use their own canonicalization rules. The problem is
that we currently filter the returned key for the full mail address
and thus we will never see a key if the service did a different
canonicalization than we. So consider this to be an experiment.

Without the rounding we saw in verbose mose

immediately without the expected one second delay. Waiting for the
next seconds did not work if nanosleep was used due to improper passed
parameters in gnupg_usleep.
Adding --debug-wait for dirmngr in daemon mode is required to test
this change.

There is no good reason to bind local port aggressively. It might be
some reason to do so, then, a user can specify it in /etc/resolv.conf
by the second argument of "interface" directive.
At least, it causes a problem on Windows. Binding a specified port in
user space can trigger the Firewall dialog on Windows. Since it can
be considered valid question, it is better not to bind with an
ephemeral port which is selected in user space, by default.

To reproduce an error, run:
./t-dns-stuff --debug --recursive-resolver www.gnupg.org
Then, it returns "No name" error. That's because there was only setup
for root servers, and no setup for recursive query in fact.

Since the migration from GNU Pth to nPth the ldap wrapper never worked

thing didn't fixed this either. The new code uses the portable
es_poll function and thus code which is tested at several other
places. It Should(tm) fix the Windows issues.

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.
