skeleton of ldap_str2nd/dn2str; works with most of the simple cases, but there's much to do with unicode, I think

use of BerkeleyDB's Concurrent DB API.

Compile with -DLDAP_CONNECTIONLESS to use this code.
For slapd, use "-h cldap://" to listen on UDP.
For ldapsearch, use "-H cldap://" to query on UDP.
Client-side support is very minimal:
  no automatic timeout/retries
  no basedn wildcard expansion on results
  no support for specifying multiple servers at once.

This should be tunable...

Remove lint

The old monitoring stuff has been removed; the new backend is
enabled by using --enable-monitor at configure time and requires

	database monitor

in slapd.conf to be activated.  At present it implements a subset
of the old monitoring options, and it should be extendable to
a number of different subsystems.  The search operation has been
implementd; it does not honor abandon or size/time limits, though.
The compare and the abandon operations are planned.

don't use tmpnam()

  - librewrite, for string rewriting; it may be used in back-ldap
    by configuring with '--enable-rewrite'. It must be used in
    back-meta. There's a text file, 'libraries/librewrite/RATIONALE',
    that explains the usage and the features. More comprehensive
    documentation will follow.
  - enhancements of back-ldap (ITS#989,ITS#998,ITS#1002,ITS#1054 and ITS#1137)
    including dn rewriting, a fix to group acl matching and so
  - back-meta: a new backend that proxies a set of remote servers
    by spawning queries. It uses portions of back-ldap and the rewrite
    capabilities of librewrite. It can be compiled by configuring
    with `--enable-ldap --enable-rewrite --enable-meta'.
    There's a text file, 'servers/slapd/back-meta/Documentation', that
    describes the main features and config statements.

Note: someone (Kurt?) should run 'autoconf' and commit 'configure' as
my autoconf version must be different: my configures contain a number
of differences and I didn't feel comfortable in adding them :)
