added new value_normalize() code
	need LDAPsyntaxes X- field support

Add needed syntaxes defs to schema_init.c

misc other clean up

Still need object classes for both of these.  Suspect we'll need
to assign "experimental" ones from our arc.

Add openldap.schema (currently empty except for a few comments) to
hold OpenLDAP specific schema items (such as for cn=monitor).

Minor schema file cleanup

former is a pseudo attribute type used internally by slapd to represent
the distinguished name of an entry and its existance should not be
visible.  The latter is an "abstract" attribute type that is not meant
to exist in practice except as supertype of other dn-valued types.
So, the definition of attribute type 2.5.4.49 has been changed to be
just distinguishedName.  Work on the OPENLDAP_DEVEL_SCHEMA branch will
treat pseudo attributes especially and will not be visible to the
clients.

Includes support for update referral for each replicated backend.
	Reworked replication test to use update referral.
Includes major rewrite of response encoding codes (result.c).
Includes reworked alias support and eliminates old suffix alias codes
(can be emulated using named alias).
Includes (untested) support for the Manage DSA IT control.
Works in LDAPv2 world.  Still testing in LDAPv3 world.
Added default referral (test009) test.

references to it for now.

Some definition reordering to satisfy dependencies.
