The future tasklet API will no longer allow to pass an arbitrary "unsigned long" data parameter. The tasklet data structure will need to be embedded into a data structure that will be retrieved from the tasklet handler. Currently, there are no ways to get the sge data structure from a given "struct sched *". This commits adds a field to store the pointer of "the parent sge" into the context of each sched, so future tasklet handlers will retrieve the "struct sched *" of the corresponding tasklet and its "struct sge *".
