dirmngr: Support new gpgNtds parameter in LDAP keyserver URLs.
* dirmngr/ldap-parse-uri.c (ldap_parse_uri): Support a new gpgNtds
extension.
* dirmngr/ks-engine-ldap.c (my_ldap_connect): Do ldap_init always with
hostname - which is NULL and thus the same if not given.  Fix minor
error in error code handling.
--

Note that "gpgNtds" is per RFC-4512 case insensitive and has not yet
been officially regisetered.  Thus for correctness the OID can be
used:

  1.3.6.1.4.1.11591.2.5          LDAP URL extensions
  1.3.6.1.4.1.11591.2.5.1          gpgNtds=1 (auth. with current user)

Note that the value must be 1; all other values won't enable AD
authentication and are resevered for future use.

This has been cherry-picked from the 2.2 branch,
commit 55f46b33df

dirmngr: Do not block threads in LDAP keyserver calls.
* 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.

This is a first take on better Active Directory support.  The main
change for NTDS in the code is that the an top-RDN of CN is used
instead of the old pgpCertID.  More changes to come; for example using

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.

dirmngr: Fix adding keys to an LDAP server.
* dirmngr/ks-engine-ldap.c (ks_ldap_put): Extract attribites into

--

The code used the wrong list which resulting in adding attributes
marked for deletion.  In particular Active Directory does not accept
such an data and rejects them.  The bug was introduced into 2.1 while
porting the code from the old keyserver helpers to dirmngr.

dirmngr: Rework of the LDAP code, part 1.
* dirmngr/http.h (struct parsed_uri_s): Add flag is_ldap.
* dirmngr/http.c (do_parse_uri): Set flag.  Do not error out for a
missing slashes in an http scheme if NO_SCHEME_CHECK is active.
* dirmngr/t-http.c (main): Print new flag.
* dirmngr/ks-engine-ldap.c (ks_ldap_help): Use flag instead of

* dirmngr/ldap-parse-uri.c (ldap_uri_p): Re-implement using
http_parse_uri.
* dirmngr/t-ldap-parse-uri.c (main): Add option --verbose.
--

This patch merely remove the separate parser for checking for an LDAP
scheme.  It is better to let our generic URI parser handle this.  Also
fixes this bug
       || url[4] == 'i' || url[4] == 'i')
to make the rarely used ldapi scheme case-insensitive.

More changes to the LDAP code are planned.

kbx: Unify the fingerprint search modes.

(KEYDB_SEARCH_MODE_FPR20, KEYDB_SEARCH_MODE_FPR32): Remove.  Switch
all users to KEYDB_SEARCH_MODE_FPR along with the fprlen value.
--

These search modes were added over time and there has until recently
be no incentive to remove the cruft.  With the change for v5 keys I
finally went over all places and allowed the generic fingerprint mode
along with a given length of the fingerprint at all places.
Consequently the other modes can now be removed.
