Added support for Novell LDAP SDK and standardized the SSL support across

the various LDAP SDKs.  Isolated the SSL functionality to mod_ldap rather than
speading it across mod_auth_ldap and mod_ldap.  Also added LDAPTrustedCA
and LDAPTrustedCAType directives to allow for a more common method of
specifying the SSL certificate.
