New state plugin callback for pagination.

Browse source 
* You need to change all statedata plugin callback for the new pagination feature
  * If you dont use pagination you can ignore the values of the new parameters
  * See [User manual pagination](https://clixon-docs.readthedocs.io/en/latest/misc.html#pagination)
  * The updated callback signature is as follows:
  ```
  int statedata(clicon_handle     h,
                cvec             *nsc,
	        char             *xpath,
	        pagination_mode_t pagmode,   // NEW
	        uint32_t          offset,    // NEW
	        uint32_t          limit,     // NEW
	        uint32_t         *remaining, // NEW
	        cxobj            *xstate)
  ```
