mk/org-fixup.el: Do not use toggle-read-only

* mk/org-fixup.el (org-make-org-version, org-make-org-loaddefs,
  org-make-local-mk, org-make-letterformat): Do not use
  `toggle-read-only' as it has been obsoleted in 24.4 and the
  replacement read-only-mode should not be used from Lisp in most
  cases. Bind `inhibit-read-only' to t instead.

ob-eval: Do not use read-only mode, switch to compilation mode only once

* lisp/ob-eval.el (org-babel-eval): Switch to compilation mode only if
  the current mode is not already (a derived mode of)
  compilation-mode.  Remove the read-only state from the buffer
  directly without using `read-only-mode'.
org-src: Fix idle auto-save feature

* lisp/org-src.el (org-edit-src-code): Fix regexp.
(org-edit-src-exit): Do not remove auto-save timer.  This is
handled by the timer itself.

`org-edit-src-save' calls `org-edit-src-exit', which then clears the
auto-save timer, thus preventing any further auto-saves before the
next `org-edit-src-code' call.

Thanks to Adriaan Sticker for reporting it.
