* gdk/x11/gdkdnd-x11.c: Remove unused variable.
* gtk/gtkdnd.c: Encapsulate storing and retrieving info
structures in functions. Fixes bug where gtk_dataset_*
was accidentally still being used in one place, causing
every dest side event to be treated independently.
* gtk/gtkdnd.c: Remove last vestages of handling
::draw (fixes warning)
* gtk/gtkentry.[ch]: Add drag and drop support.
* gtk/gtkdnd.[ch] gtk/gtktextview.c gtk/gtkentry.c: Add
new function gtk_check_drag_threshhold() for checking
to check if (dx,dy) has exceeded the threshhold for starting
a drag and use it everywhere.
