Improve `org-promote' and `org-demote'

* lisp/org.el (org-promote, org-demote): Fix docstring.  Small
  refactoring.  Ignore narrowing.
(org-fixup-indentation): Smarter indentation: handle inlinetasks and
footnote definitions.

* testing/lisp/test-org.el (test-org/demote, test-org/promote): New
  test.

`org-called-with-limited-levels' check is removed when promoting
a top-level headline.  The motivation behind it in this particular
case wasn't clear (see 10aba6b1261a47a2aa4862b7222f87814af7ba31) and
I couldn't find a good reason to keep it.

org-plot: Reset gnuplot process instead of killing it

org-plot.el (org-plot/gnuplot): Do not kill the gnuplot process. just
jump to end of buffer and rely on command to do the resetting job.

Without this patch, the gnuplot process associated to the gnuplot
buffer is killed before each batch of instructions from orgmode to
gnuplot.  With or without this patch, Org mode sends a reset
instruction to the gnuplot process as first instruction.

org-plot: Correction in callback registration

org-plot.el (org-plot/gnuplot): Correct the callback for the and
register it as soon as possible.

The data-file variable is not in the scope of the callback, one needs
to grab its value while registering the callback.  With this patch the
timer is set as soon as the file is created.  Without this patch the
timer is set at the end of a let-block, if anything goes wrong in the
let-block before the timer is set, the file will not be removed.
