Auto-fill shouldn't insert new items

* lisp/org-list.el (org-list-in-valid-context-p): renamed from
  org-list-in-valid-block-p.
  (org-at-item-p,org-list-search-generic): use renamed function.

* lisp/org.el (org-fill-item-nobreak-p): new function.
  (org-set-autofill-regexps): modify `fill-nobreak-predicate' to
  prevent auto-fill from breaking line just before an item regexp.
