[PATCH RFC inputproto] specs: Don't allow for early acceptance/rejection

Definition of early acceptance/rejection: If supported, a client may accept
or reject a touch sequence before it becomes the current owner of the
sequence. In some cases, this can speed up touch processing as it removes
one ore more clients from the listeners and thus reduce the number of events
to send and process client-side.
Unfortunately, we likely won't have time to implement early
acceptance/rejection for XI 2.2 so drop it from the protocol. This can
easily be added in XI 2.3 if we get the time to implement it.

I'm going to hold this patch back until we really can't get the patches
into the server anymore but I really doubt we'll get this feature in time.
It's quite easy to add to XI 2.3 (reverting this patch) once we have the
implementation in place.
Meanwhile, a heads up, this part will likely be dropped from 2.2
