unifying ob-process-params and ob-expand-variables

* lisp/ob-exp.el (org-babel-exp-results): replaced old function call

* lisp/ob-lob.el (org-babel-lob-execute): replaced old function call

* lisp/ob-ref.el (org-babel-ref-parse): removed obsolete optional
  params argument, also no longer chokes when handed an
  already-resolved reference

  (org-babel-ref-resolve): removed obsolete optional params argument

* lisp/ob.el (org-babel-ref-parse): updated function declaration
  (org-babel-get-src-block-info): replaced old function call
  (org-babel-header-arg-names): indentation
  (org-babel-execute-src-block): now expanding all parameters using
  the newly combined org-babel-process-params
  (org-babel-switch-to-session-with-code): indentation
  (org-mode-hook): indentation
  (org-babel-process-params): now packages all results into the
  parameter alist and does variable expansion, this should no longer
  be called from inside of language functions
  (org-babel-expand-noweb-references): updated function call for newly
  removed obsolete function parameter
