commit f5bc1c6681d6fd91d5c9f804b1dc7be7be9b4d68
Author: Sébastien Wilmet <swilmet gnome org>
Date: Mon Apr 25 15:39:52 2016 +0200
gtef: add utils functions
- copy gedit-utils
- remove deprecated macros and functions
- remove gedit_warning() since it takes a variable number of arguments
(it would be a bit more work for gedit_warning() to call
gtef_warningv()).
- replace gedit_debug_message() by a g_warning(), to not depend on
gedit-debug.
- rename gedit -> gtef
