[devhelp] Better #includes in the app to access the libdevhelp

[Sébastien Wilmet <swilmet src gnome org>]

commit 34e76f0ff7d6b0d015d78e37b20295f03f08debc
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Thu Feb 22 18:31:04 2018 +0100

    Better #includes in the app to access the libdevhelp
    
    - For public/installed libdevhelp headers, #include <devhelp/devhelp.h>
      only.
    - For semi-private/non-installed/problematic libdevhelp headers,
      #include "devhelp/dh-something.h".
    
    When the libdevhelp git repo will be created, it will no longer be
    possible to #include in the app the non-installed libdevhelp headers.
    
    So the two problematic headers in devhelp/ are:
    - dh-setting.h
    - dh-util.h
