possible clarification of EXPORT_FUNCTIONS for user manual

["Robert P. J. Day" <rpjday@crashcourse.ca>]

  so, just to make sure i'm understanding this correctly, in section
3.4.5 of BB user manual, discussion of EXPORT_FUNCTIONS talks about
the general concept of exporting *functions*, but the entire section
uses exclusively "do_" examples, which might mislead the reader into
thinking it's good only for *tasks*.

  i decided to look through the oe-core layer for examples of
exporting an actual function, and i found all of one example -- in
meta/classes/debian.bbclass:

  python debian_package_name_hook () {
      ... snip ...
  }
  ...
  EXPORT_FUNCTIONS package_name_hook

which seems like a valid example of exporting a function, except i
can't find a single example of this function being used anywhere else.
am i missing something?

  anyway, i guess my point is that that section could be tweaked to
emphasize that exporting works for both functions and tasks, although
the only function example i found seems unused. thoughts?
