Flag Day: no
Doc impact: no

This patch includes
- replacing the entrydn index with the entryrdn index
- replacing a full DN in each entry in the DB with an RDN
- extending Slapi_Entry, entry2str, and str2entry to absorb the changes
  made on the entry
- adding DN/RDN helper functions
- adding DN cache
- adding a utility and a migration script to convert the DN format database
  to the RDN format
- extending a database dump utility dbscan to support the entryrdn
- slapi_dn_syntax_check by nkinder@redhat.com is added to check the dn before
  modify operations
- big fix for 171338 - Enhancement: winsync modrdn not synced

In addition to the above, compile warnings and memory leaks found in testing
the new feature are fixed.

This adds support for the newly proposed LDAP Dereference feature (not to
be confused with alias dereferencing).  The details of the proposed feature
can be found here:
http://www.openldap.org/devel/cvsweb.cgi/~checkout~/doc/drafts/draft-masarati-ldap-deref-xx.txt
This adds a new deref plugin to the directory server.  This is a pre op search
plugin.  In order to allow the plugin to rewrite the controls sent back with
each entry, I changed the way pre-search and pre-entry plugins work.  They now
have the ability to alter the entry and controls just before being sent back
to the client.
This plugin does not currently support internal operations.  It should be easy
to add a call to register the plugin for internal ops if we need to do that.
The code supports real, computed (e.g. memberOf), and virtual attributes
both as the attibute to dereference and in the list of attributes to return
from each dereferenced entry.  This will allow us to use attributes such as
nsRole as the derefattr.
Tested on RHEL5 x86_64 with various openldap 2.4.15+ and Net::LDAP clients.
valgrind output is clean

A change was also made to Makefile.am to avoid library versioning
for our C++ plug-in libraries.  This change should allow us to use
autogen.sh on recent platforms without running into issues during
build-time.

Summary: Add support for 64-bit counters (phase 1).

Summary: Add CLI for dynamic reload schema file task

Summary: Added CLI for creating memberOf fix-up task entry.
