dirmngr: Support the new Active Directory schema

* dirmngr/ks-engine-ldap.c (SERVERINFO_): New constants.
(my_ldap_connect): Relace args pgpkeyattrp and real_ldapp by a new
serverinfo arg.  Set the new info flags.
(ks_ldap_get): Adjust for change.
(ks_ldap_search): Ditto.
(ks_ldap_put): Ditto.  Replace xmalloc by xtrymalloc.  Change the DN
for use with NTDS (aka Active Directory).
* doc/ldap/gnupg-ldap-init.ldif (pgpSoftware): Update definition of
pgpVersion.
* doc/ldap/gnupg-ldap-ad-init.ldif: New.
* doc/ldap/gnupg-ldap-ad-schema.ldif: New.
--

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
and storing the fingerprint.

#
# Schema for an OpenPGP LDAP keyserver. This is a slighly enhanced
# version of the original LDAP schema used for PGP keyservers as
# installed at quite some sites.
# Revision: 2020-12-08
# Some notes:
# - Backup your AD! It is not possible to revert changes of the schema.
# - Try it first on a test system.
# - To import the new attributes and classes use:
# ldifde -i -vv -f gnupg-ldap-ad-schema.ldif
# -c "DC=EXAMPLEDC" "DC=example,DC=org"
# (the above command is given as one line)
# - The schema does not get its own distingished name as done with OpenLDAP.
# - The first GUID we use is f406e7a5-a5ea-411e-9ddd-2e4e66899800
# and incremented for each attribute.
#
# - Some OIDs, oMSyntax, and original OIDs:
# 2.5.5.1 (127) Object (DS-DN) (1.3.6.1.4.1.1466.115.121.1.12)
# 2.5.5.3 (27) Case-sensitive string
# 2.5.5.9 (2) 32 bit signed integer
# 2.5.5.10 (4) Octet string (1.3.6.1.4.1.1466.115.121.1.26)
# 2.5.5.11 (23) UTC-Time string
# 2.5.5.12 (64) Case-insensitive Unicode string
# 2.5.5.12 (64) Directory String in UTF-8 (1.3.6.1.4.1.1466.115.121.1.15)
# 2.5.5.16 (65) 64 bit signed integer
# The base DN for the PGP key space by querying the
# pgpBaseKeySpaceDN attribute (This is normally
