From now on, the state computation will be done in the middle hook call, with a
priority higher than default. We will define this priority as PRIO_STATE,
-defined to -10.

-If state has to be computed, lttv_process_traceset_begin is called to add state
-hooks to the context. Then, the state seek_closest will have to be used to
-restore the nearest state, plus a process_traceset with no hooks present other

-real time seeked.

computation is needed.

position. We keep information about number of tracefiles for extra integrity

We modify lttv_process_traceset_middle so that it takes as arguments :

LttTime end,
-unsigned num_events,
+unsigned nb_events,
const LttvTracesetContextPosition *end_position)
-This new version of process traceset middle will call the middle hooks for
-events until the first criterion is fulfilled : either the end time is passed,
-the number of events requested is passed or the end position is reached. When
-this function ends, the end position can be extracted from the context, the end
-event is set as described below and the number of events read is returned.
