Configuration sync optimization for Oracle

For Zabbix installations with Oracle, it is now possible to manually change item and item preprocessing database field types from nclob to nvarchar2 by applying a database patch.

Patch application may increase the speed of configuration sync in environments with large number of items and item preprocessing steps, but will reduce the maximum field size limit from 65535 bytes to 4000 bytes for some item parameters. See Known issues for details.
