Remove lint

Added the suffix=<dn> parameter to replica config directive
to allow selective replication of subtrees of a single database.
Multiple occurrences allow the same replica to handle different
subtrees

Now operations that set the status of an entry to CREATING (add.c, modrdn.c)
need to set it to COMMIT, by calling cache_entry_commit, before returning
the entry itself, otherwise the entry is removed from the cache
and its private data is freed.
Should fix crashes due to add failures as in ITS#1245

Reworked API of nextid; e_private gets destroyed separately from the entry in case add fails (should fix ITS#1245)

Unicode cannonical normalization

dbsync configuration is in use, which was preventing the performance
gains of this mode.

slapadd core-dumps when destroying db's env (Sleepycat 3.2.9) (ITS#1239)
Only call ldbm_shutdown_env if the database has been opened, ie. when
li->li_dbenv != NULL.  Would appear any time a shutdown occurred and
not all LDBM databases were opened.

UTF8 normalization must be done before we compute number of keys since
string length might increase.

be applied to substrings assertions as well.

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.

added function cache_find_entry_ndn2id that avoids an unnecessary call to dn_normalize; now dn2id calls this function, while the original function has been left as a wrapper

OpenLDAP 2.x is supported.

and ldap_next_attribute if using newer interface.  Current test for this
is an #if LDAP_API_VERSION >= 2004.

reworked rdn_attrs to use ldap_explode_rdn; maybe we should remove escapes "\" from parts directly in ldap_explode_rdn

by slapd/tools/*; slap_mods_free is needed by ldbm_back_modrdn after
fixing ITS#1184 (at present -DMULTIATTRVAL_RDN is needed when compiling
back-ldbm/modrdn.c to trigger the compilation of new code).
