dirmngr: Change the default keyserver.
* configure.ac (DIRMNGR_DEFAULT_KEYSERVER): Change to
keyserver.ubuntu.com.

* dirmngr/certcache.c (cert_cache_init): Disable default pool cert.
* dirmngr/http-ntbtls.c (gnupg_http_tls_verify_cb): Ditto.
* dirmngr/http.c (http_session_new): Ditto.

* dirmngr/server.c (make_keyserver_item): Use a different mapping for
the gnupg.net names.
--

Due to the unfortunate shutdown of the keyserver pool, the long term
defaults won't work anymore.  Thus it is better to change them.

For https access keyserver.ubuntu.com is now used because it can be
expected that this server can stand the load from newer gnupg LTS
versions.

For http based access the Dutch Surfnet keyserver is used.  However
due to a non-standard TLS certificate this server can not easily be
made the default for https.

Note: that the default server will be changed again as soon as a new
connected keyserver infrastructure has been established.

dirmngr: Fix regression in KS_GET for mail address pattern.
* dirmngr/ks-engine-hkp.c (ks_hkp_search): Munge mail address pattern.

-

Before the keyserver changes in 2.2.28 gpg passed dirmngr a pail

the mail address is detected gpg gpg and we see for example
"<foo@example.org>".  This patch fixes this to turn a mail address
into an exact match again.

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).

For background see these comments from gpgme:

/* The format is:

   pub:<keyid>:<algo>:<keylen>:<creationdate>:<expirationdate>:<flags>

   as defined in 5.2. Machine Readable Indexes of the OpenPGP
   HTTP Keyserver Protocol (draft).  Modern versions of the SKS
   keyserver return the fingerprint instead of the keyid.  We
   detect this here and use the v4 fingerprint format to convert
   it to a key id.

   We want:
   pub:o<flags>:<keylen>:<algo>:<keyid>:<creatdate>:<expdate>::::::::
*/

Regarding the freeing of values: I was not able to find a
specification stating it is okay to pass NULL to ldap_value_free, thus
the new wrapper.  Also add robustness measures in case ldap_get_value
returns an empty array.

dirmngr: LDAP search by a mailbox now ignores revoked keys.
* dirmngr/ks-engine-ldap.c (keyspec_to_ldap_filter): Ignore revoked
and disable keys in mail mode.
--

The LDAP schema has a revoked and a disabled flag.  The former will be
set if a revoked key is uploaded; the latter can be set by other
means.   With this change a search by mailbox does not anymore return
keys with these LDAP attributes set.  This allows to better maintain a
directory with multiple keys per mailbox.

Doing the same for expired keys could also be done but requires more
effort.

--

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.

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.

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.

gpgconf: Also print revision of libksba.
* dirmngr/dirmngr.c (get_revision_from_blurb): Fix detection of empty
string.
(gpgconf_versions): Print ksba revision.

The latest Libksba version support retrieving of the revision (commit)
id.  We now use that or print a question mark.

w32: Support Unicode also for config files etc.
* common/sysutils.c (gnupg_fopen) [W32]: Use _wfopen if needed.   Use
new function in most places where fopen is used.
--

The config files in 2.2 are still read using fopen - we need to change
this to allow Unicode directory names.  There is also one case where
files are written using the old fopen.  The new option parser in 2.3
does not have this problem but at some places fopen is also still used.

This is required to correctly handle non-ascii filenames on Windows.

gpg-connect-agent: Catch signals so that SIGPIPE is ignored.
* dirmngr/server.c (cmd_killdirmngr): Return 0.
* tools/gpg-connect-agent.c (main): Catch signals.
--

And we also print nicer diagnostics.  The reason we need this is that
for example "gpgconf --kill dirmngr" uses gpg-connect-agent to send a
command to dirmngr.  This may results in a SIGPIPE which in turn leads
to an annoying error message from gpgconf.

* dirmngr/http.c (http_session_new) <gnutls>: Use only the special

--

The gnutls version uses a different strategy than the ntbtls version
on when to use the special SKS pool certificate.  This patch aligns it
so that we don't need to wonder about different kind of bug reports.
In short the special cert is now the only cert use with the default
keyserver.
