[PATCH RFC inputproto] Provide convenience defines for owner_events.

[Peter Hutterer]

No functional effect, just to improve readability of code.

It's not obvious what "True" or "False" stands for in a function with 11
arguments. Compare
    XIGrabButton(dpy, deviceid, button, grab_window, cursor,
                 GrabModeAsync, GrabModeSync, True,
                 event_mask, num_modifiers, &modifiers);
with
    XIGrabButton(dpy, deviceid, button, grab_window, cursor,
                 GrabModeAsync, GrabModeSync, XIOwnerEvents,
                 event_mask, num_modifiers, &modifiers);

Man, I bet I'll get a nobel price for that.
