* add per-display gdk_x11_display_error_trap_push() (X11-specific because gdk_error_trap_push() probably should have been) * make gdk_error_trap_push() handle only GDK displays not displays opened without a GDK wrapper * make gdk_error_trap_pop() and gdk_x11_display_error_trap_pop() automatically sync only if needed, so manual gdk_flush() is not required * add gdk_error_trap_pop_ignored() which just asynchronously ignores errors, so never needs to sync * add G_GNUC_WARN_UNUSED_RESULT to plain pop(), because if you use plain pop() and don't need the return value, the async gdk_error_trap_pop_ignored() should be used instead. This results in lots of warnings to clean up in a later patch. The main objective here was to avoid the need to sync just to ignore an error. Now, syncing is automatic, and only happens when we need to know the error code. https://bugzilla.gnome.org/show_bug.cgi?id=629608
