dix: add touch event history helper functions
If touch client has not registered for ownership events and a grab above
that client is rejected, the client needs to receive the complete event
history.
The history currently doesn't really do fancy overflow handling. We assume
that the first TOUCH_HISTORY_SIZE events are the important ones and anything
after that is dropped. If that is a problem, fix the client that takes > 100
event to decide whether to accept or reject.
Events marked with TOUCH_CLIENT_ID or TOUCH_REPLAYING must not be stored in
the history, they are events created by the DIX to comply with the protocol.
Any such event should already be in the history anyway.
A fixme in this patch: we don't have a function to actually deliver the
event yet.
