* New state callback signature (ca_statedata2)

* The new callback contains parameters for paging
   * Goal is to replace ca_statedata callback
* New plugin callback when lock/unlock occurs
  * Add `ca_lockdb` tro plugin init to use it.
* Fixed: Typing 'q' in CLI more paging did not properly quit output
  * Output continued but was not shown, for a very large file this could cause considerable delay
* Fixed: Lock was broken in first get get access
  * if the first netconf operation to a backend was lock;get;unlock, the lock was broken in the first get access.
