It is easier to have a generic flags arg instead of adding more and
more dedicated args.  verbose and debug are kept as they are because
they are not boolean.

We now rely on the dirmngr to parse the keyserver specs.  Thus a bad
specification will not be caught immediately.  However, even before
that dirmngr had stricter tests.

--

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was later superseded by an experimental DANE method and is today not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.

dirmngr: Do not store the useless pgpSignerID in the LDAP.
* 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.

  gpg: Note: server uses an invalid certificate
  gpg: (further info: bad cert for 'posteo.net': \
                      Hostname does not match the certificate)
  gpg: error retrieving 'dd9jn@posteo.net' via WKD: Wrong name
  gpg: error reading key: Wrong name

(without -v the "further info" line is not shown).  Note that even
after years Posteo is not able to provide a valid certificate for
their .net addresses.  Anyway, this help to show the feature.

The Web Key Directory is an experimental feature to retrieve a key via
https.  It is similar to OpenPGP DANE but also uses an encryption to
reveal less information about a key lookup.

For example the URI to lookup the key for Joe.Doe@Example.ORG is:

    https://example.org/.well-known/openpgpkey/
    hu/example.org/iy9q119eutrkn8s1mk4r39qejnbu3n5q

(line has been wrapped for rendering purposes).  The hash is a
z-Base-32 encoded SHA-1 hash of the mail address' local-part.  The
address wk@gnupg.org can be used for testing.

Along with the corresponding dirmngr change this option allows to

configurations will continue to work.  However, GUIs using gpgconf
now the keyserver option under the dirmngr (aka Key Acquirer) tab
unless they are in export mode in which the keyserver option is also
show for gpg.

gpg: Report a conflict between honor-keyserver-url and TOR.
* g10/call-dirmngr.c (create_context): Send option and print a verbose
error.
--

It is in general a bad idea to use honor-keyserver-url but if Dirmngr
is running in TOR mode we should not allow this option at all.  We let
Dirmngr know about the use of this option and let Dirmngr tell use
whether TOR mode is active so that we can print a hint to disable that
keyserver option.

A future extension in gpgconf may disable that option directly but a
user may still override that and thus we better check.

With this patch gpg does not do any network access itself but uses

the logging code and because we need TCP for our socket emulation
under Windows.  Probably also required for Solaris etc.

Note that refreshing all keys still requires way to much memory
because we build an in-memory list of all keys first.  It is required
to first get a list of all keys to avoid conflicts while updating the
key store in the process of receiving keys.  A better strategy would
be a background process and tracking the last update in the key store.

It has often been requested that the actually used IP of a keyservers

the keyserver is actually a pool of keyservers.  This patch does this.
