    Subject[RFC 1/12][PATCH] Extended scheduling parameters structure added.
    An extended scheduling parameter structure, sched_param_ex, is defined in
    this commit, as the starting point for supporting task models more
    sophisticated than fixed-priority.

    One that is both popular and (hopefully!) general enough is the so-called
    sporadic task model, in which tasks' computation is divided into instances,
    each one with:
    * a (maximum/typical) execution time,
    * a minimum interval between the activation of two consecutive instances,
    * a time instant by which the computation of the instance must be completed.

    The new sched_param_ex reflects this model, and thus allows for better
    specification of time sensitive workloads typical, for example, in real-time,
    control and/or continuous media applications.
