Merge branch dispatcher and broke out pagination callbacks to use it

Browse source 
* Merge branch 'dcornejo-master'
* Broke out pagination callback API from state data callbacks
  * New pagination callback API uses new dispatcher from netgate, thanks @dcornejo
   * Register callback with: `clixon_pagination_cb_register()`
   * Use accessor functions `pagination_offset()`, `pagination_limit()`, etc
 * Reverted state data callback API to pre-5.3 (see C/CLI API changes below)
