Subject: js: Extract pagination model.

* js/utils.js (guix.clamp): New function.
* js/controller/packages.js (guix.packages.controller): Remove 'pages',
  'currentPageIndex', and 'pageSize' properties.  Add 'pager' prop.
  Delete 'paginate', 'currentPage', 'isFirstPage', 'isLastPage', and
  'isCurrentPage' methods.
* js/model/packages.js (guix.packages.Pager): New function.
* js/view/packages.js (guix.packages.view): Use new Pager API.
