and make application be tolerant to the termination of input method.

Changes:

gdk/gdktypes.h:
 * Add new enum GdkICAttriburesType, and new struct GdkICAttr.

gdk/gdk.c:gdk_ic_new(), gdk_ic_set_attr (), gdk_ic_get_attr ()
 * Changes API from VaList based to Attribute structure based.
   Now gtk application may not clash when input method dies !!

gdk/gdk.c:gdk_ic_{set|get}_values()
 * removed.
   
gdk/gdk.c:gdk_event_get ()
 * Fix freeze related with redireciton of XFilterEvent.

gdk/gdk.c:gdk_event_translate ()
 * Suppress the "lookup reeveals NULL" message related with XIM.
 * Ignores the FocusIn/FocusOut event of which mode is Notify{Grab|Ungrab}
   for avoid to confuse ICFocus.

gtk/gtkeditable.h:
 * Add new member ic_attr.

gtk/gtkeditable.c: gtk_editable_finalize ()
 * remove this method. gdk_ic_destroy () must be called in more
   intimate widget, which knows the client_window and destroys ic exactly
   before client_window.

gtk/{gtkentry.c|gtktext.c}:gtk_*_unrealize ()
 * call gdk_ic_destroy in this method.

gtk/gtkentry.c:gtk_entry_draw_cursor_on_drawable ()
 * Check if widget has focus for cope with some IM.
   With this im, setting attributes to ic which does not have ic_focus caused
   problem.

gtk/gtkwidget.c:gtk_wiget_real_unrealize()
 * Unrealize child widget before parent.


KNOWN BUG:

 * If input method dies during processing XFilterEvent, it seems there is
   no way to prevent a application clashing.

 * If input method is not running when gtkeditable or it's descendant is
   realized, that widget can't use XIM. If you want to use XIM, you must
   destroy the widget and re-create it (e.g. close the window and open again).
 
 * If different IM starts and it's capability (i.e. supported style,
   required filter_events, etc) is differ than previous IM, result is
   unpredictable.
