Allow modrdn to move subtree and rename non-leaf node

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.

    http://directory.fedoraproject.org/wiki/Subtree_Rename
