OpenLDAP supportcleanup

These changes allow the server to be built with OpenLDAP (2.4.17+). A brief summary of the changes:
* #defines not provided by OpenLDAP were copied into slapi-plugin.h and protected with #ifndef blocks
* where it made sense, I created slapi wrapper functions for things like URL and LDIF processing to abstract way the differences in the APIs
* I created a new file utf8.c which contains the UTF8 functions from MozLDAP - this is only compiled when using OpenLDAP
* I tried to clean up the code - use the _ext versions of LDAP functions everywhere since the older versions should be considered deprecated
* I removed some unused code
NOTE that this should still be considered a work in progress since it depends on functionality not yet present in a released version of OpenLDAP, for NSS crypto and for the LDIF public API.
